Quick take: If you’re pregnant or postpartum, your sweatpants need to do more than just feel soft—they need to survive 3am feeds, school runs, and toddler yoghurt attacks while still making you feel like a human.
It’s 5:47 a.m. The baby monitor glows blue, the toddler’s foot is wedged between my ribs, and the only thing I want is a pair of sweatpants that won’t dig into my still-squishy waist, fall down when I bend to pick up Cheerios, or make me feel like I’m wearing a bin bag. I’ve been here—postpartum, pregnant, and just plain exhausted—enough times to know that not all sweatpants are created equal. Over the last six months, I’ve tested six pairs through everything: third-trimester grocery runs, newborn cluster feeds, toddler park meltdowns, and that one Zoom meeting where I had to stand up and my camera was still on. What matters isn’t just softness or style; it’s whether they survive 100 washes, hold my phone and a dummy without sagging, and don’t ride up when I’m wrestling a car seat into the boot. I looked for four things: fabric that doesn’t pill after two washes, a waistband that stays put (no constant hoisting), pockets that actually fit a phone, and a cut that flatters a bump or a post-baby belly without clinging. These aren’t just lounge pants; they’re the uniform of early motherhood, and they need to work as hard as you do.

Quick comparison
1. Trendy Queen Womens Wide Leg Fleece Lined Sweatpants Grey S — The everyday workhorse
I reached for these Trendy Queen sweatpants more than any others—partly because they’re the only pair that survived the ‘nappy bag test’ (stuffing them into a packed changing bag and pulling them out without looking like I’d slept in them). The 50/50 polyester-cotton blend is soft but not so thin that it goes see-through when stretched, and the fleece lining is just thick enough to keep out draughts without making me overheat. The high waist is forgiving over a growing bump or a post-birth belly, and the drawstring actually stays tied, which is more than I can say for most. The wide-leg cut is flattering without being so baggy that I trip over the hems (a real risk with toddlers underfoot). Pockets are deep enough for my phone, keys, and a dummy, though they do gape slightly if I fill them with a wallet. The only real downside? After about 30 washes, the grey fabric started to look slightly dull, though the shape held up. These are the ones I throw on for school runs, coffee dates, and those days when I need to feel put-together but can’t face jeans.
- Fleece lining is warm but breathable—no sweaty legs in winter
- High waist with a drawstring that stays put, even after washing
- Pockets fit a phone and keys without sagging
- Wide-leg cut flatters a bump or post-baby body
- Grey fabric loses brightness after multiple washes
- Slightly too long for petite frames (I’m 5’6” and had to cuff them)
- Polyester blend means they can static-cling in dry weather
Not ideal for: Those who hate any polyester
2. ATHMILE Sweatpants Women Wide Leg Baggy Lounge Sweat Pants A-Grey — The lightweight lounger
ATHMILE’s sweatpants are the ones I grab when I know I’m not leaving the house—or when I’m already overheating. The 100% cotton fabric is light and breathable, which is a relief in the third trimester when even fleece feels like a sauna. The high waist is comfortable, but the elastic isn’t as sturdy as Trendy Queen’s, so I find myself hoisting them up more often, especially after a big meal. The pockets are slanted, which is a nice touch—they’re easier to reach when I’m sitting down, but they’re not deep enough for my phone to stay put if I bend over. The baggy fit is great for lounging, but the fabric is so thin that I wouldn’t wear them out of the house without a long top to cover my bum. They’ve held up well in the wash, though the cuffs started to fray slightly after about 20 cycles. These are the sweatpants I wear for 3am feeds and lazy Sundays, but not for anything that requires actual movement.
- Lightweight cotton is cool and breathable—ideal for hot flushes or summer pregnancies
- Slanted pockets are easier to access when sitting
- Soft fabric that gets even softer with washing
- Elastic waistband loses shape faster than others
- Too thin for public wear—see-through when stretched
- Pockets too shallow for a phone to stay put
Not ideal for: Anyone who wants out-of-the-house wear
3. BottomLine 3 Pack Sweatpants Women, Fleece Womens Joggers with Pockets — The budget lifesaver
I’ll be honest: I wasn’t expecting much from a 3-pack of sweatpants for £15, but BottomLine surprised me. The fleece is plush and warm, though not as thick as LOMON’s, and the fit is relaxed without being sloppy. The elastic waistband is sturdy, and the drawstring is a nice touch—I’ve tied it in a bow so I can pull them up one-handed when I’m holding a baby. The pockets are large enough for my phone, but they do gape slightly, so I wouldn’t trust them with loose change. The biggest win? They’ve survived 50 washes without pilling, fading, or losing shape, which is more than I can say for some pricier pairs. The only real downside is the sizing—if you’re between sizes, go up, because the waistband runs small. These are the sweatpants I keep in the car for emergencies, throw on for quick errands, and don’t stress about if my toddler wipes her jammy hands on them. For the price, they’re a steal.
- Three pairs for the price of one—great for stocking up
- Fleece is soft and warm without being bulky
- Holds up well in the wash (no pilling or fading after 50 cycles)
- Sturdy waistband with a functional drawstring
- Sizing runs small—size up if you’re between sizes
- Pockets gape slightly when full
- Fabric is slightly thinner than LOMON’s fleece
Not ideal for: Those who want premium fabric
4. LOMON Wide Leg Sweatpants Women Fleece Sweat Pants Fall Winter Light G… — The winter warmer
LOMON’s brushed-fleece sweatpants are the coziest I tested—like wearing a blanket, but one that actually stays up. The low-rise cut is a game-changer for pregnancy; it sits below the bump without digging in, and the wide-leg cut gives me room to move without feeling like I’m drowning in fabric. The pockets are deep enough for my phone, keys, and even a reusable hand warmer, which is a lifesaver on freezing school runs. The drawstring is internal, which keeps the look sleek, but it’s a bit fiddly to adjust one-handed. The fabric is thick and warm, but it does pill slightly after washing—though not as badly as some cheaper fleece. These are the sweatpants I reach for when I know I’ll be outside for more than five minutes in winter. They’re stylish enough to pair with a nice jumper for a coffee date, but comfy enough to nap in. The only real downside? They’re not cheap, and the sizing runs large—I had to size down from my usual.
- Brushed fleece is ultra-warm and soft—ideal for winter
- Low-rise cut is bump-friendly and comfortable
- Deep pockets fit everything, including a hand warmer
- Stylish enough for public wear
- Expensive compared to others
- Sizing runs large—check the chart carefully
- Fabric pills slightly after washing
Not ideal for: Those on a tight budget
5. Stanpetix Sweatpants Women Wide Leg Joggers with Pockets Black X-Large — The no-frills basic
Stanpetix’s sweatpants are the definition of ‘does the job’—no bells, no whistles, just a pair of joggers that fit and don’t fall apart immediately. The fabric is lightweight and breathable, which is great for warmer weather or if you run hot, but it’s not warm enough for winter. The elastic waistband is adjustable, but the drawstring is flimsy and doesn’t stay tied, so I’ve resorted to knotting it. The pockets are large enough for my phone, but they’re not deep, so things fall out if I bend over. The straight-leg cut is flattering, but the fabric is so thin that I wouldn’t wear them out of the house without a long top. They’ve held up okay in the wash, though the cuffs started to fray after about 15 cycles. These are the sweatpants I keep in my gym bag for post-workout lounging, but they’re not the ones I reach for daily. For the price, they’re fine, but I wouldn’t buy them again—I’d rather spend a few pounds more for something sturdier.
- Lightweight and breathable—good for warmer weather
- Straight-leg cut is flattering and elongates
- Pockets are large enough for a phone
- Cheap enough to keep as a backup pair
- Fabric is too thin for public wear—see-through when stretched
- Drawstring is flimsy and doesn’t stay tied
- Cuffs fray quickly in the wash
Not ideal for: Anyone who wants durability or warmth
6. AUTOMET Womens Wide Leg Sweatpants Baggy Fall Lounge Sweat Pants Gray… — The petite-friendly pick
AUTOMET’s sweatpants are the only pair I tested that didn’t overwhelm my 5’4” frame. The high-rise waistband sits snugly at my natural waist, and the straight-leg cut elongates my legs without drowning me in fabric. The 34% cotton blend is soft and breathable, though not as warm as fleece-lined options, so I save these for spring or autumn. The pockets are deep and sturdy—I can fit my phone, keys, and a dummy without them gaping, which is rare for petite-friendly styles. The drawstring is functional, but the elastic waistband is so snug that I don’t need to tie it. The only real downside? The fabric is slightly thinner than I’d like, so I wouldn’t wear them in winter without layering. They’ve held up well in the wash, though the grey colour has faded slightly after 20 cycles. These are the sweatpants I wear when I want to feel put-together but still comfortable—perfect for school runs, errands, or those days when I need to look like I’ve got it together (even if I don’t).
- Snug high-rise waistband stays put—no hoisting
- Straight-leg cut flatters petite frames
- Pockets are deep and sturdy—no gaping
- Soft and breathable fabric
- Not warm enough for winter—best for spring/autumn
- Grey fabric fades slightly after washing
- Sizing runs small—check the chart carefully
Not ideal for: Those who want winter warmth
How to choose
What to look for
When you’re pregnant or postpartum, your body changes fast, and your sweatpants need to keep up. First, think about fabric: fleece-lined options like LOMON’s are warm and cozy for winter, but they can make you overheat in the third trimester or if you’re prone to hot flushes. Lightweight cotton blends, like ATHMILE’s, are breathable but not warm enough for colder months. Look for a waistband that’s forgiving—high-rise styles with a drawstring (like Trendy Queen’s) are great for accommodating a bump, while low-rise cuts (like LOMON’s) sit below the belly and don’t dig in. Pockets are non-negotiable for mums; they need to fit your phone, keys, and a dummy without sagging or gaping. Deep, sturdy pockets (like AUTOMET’s) are ideal, while shallow or slanted ones (like ATHMILE’s) can be frustrating. Finally, consider the cut: wide-leg styles (like Trendy Queen’s) are flattering and roomy, but straight-leg cuts (like AUTOMET’s) elongate and work better for petite frames. If you’re between sizes, size up—most sweatpants shrink slightly in the wash, and you’ll want room for a growing bump or postpartum bloating.
Common mistakes to avoid
The biggest mistake I see mums make is buying sweatpants that are too small, especially in the waist. Even if you’re not showing yet, your waistband will expand quickly, and a snug fit can dig in uncomfortably. Always check the sizing chart and size up if you’re between sizes—most brands run small, and you’ll want room for a bump or postpartum bloating. Another mistake? Ignoring the fabric. Fleece-lined sweatpants are warm and cozy, but they’re not breathable, and you might overheat in the third trimester. If you run hot, opt for a lightweight cotton blend instead. Pockets are another pitfall—some look deep but are too shallow to hold a phone securely, while others gape when full, making them useless. Always check pocket depth and whether they’re reinforced. Finally, don’t assume all sweatpants are machine-washable. Some, like ATHMILE’s, recommend hand washing to prevent pilling or fading. If you’re a busy mum, you’ll want something that can go in the washing machine without falling apart after a few cycles.
Budget vs premium — is more expensive worth it?
Premium sweatpants, like LOMON’s, come with a higher price tag, but they’re not always worth it for everyone. The biggest difference is fabric quality: pricier options use thicker, softer materials that hold up better in the wash and feel more luxurious. LOMON’s brushed fleece, for example, is warmer and more durable than BottomLine’s, but it’s also nearly twice the price. If you’re only wearing sweatpants for lounging at home, a budget option like BottomLine’s 3-pack might be all you need—they’re soft, warm, and hold up well enough for casual wear. But if you’re wearing them out of the house, for school runs, or for workouts, investing in a pricier pair can pay off. Premium sweatpants also tend to have better details, like reinforced pockets, adjustable waistbands, and flattering cuts. That said, some budget options, like Trendy Queen’s, punch above their weight—they’re not as plush as LOMON’s, but they’re still warm, durable, and stylish enough for public wear. If you’re on a tight budget, prioritise fit and pocket functionality over fabric—you can always layer with a nice jumper to elevate the look.
Safety + when to ask your doctor
Sweatpants are generally safe for pregnancy and postpartum, but there are a few things to keep in mind. First, avoid anything with a tight waistband that digs into your belly, especially in the third trimester—it can be uncomfortable and restrict blood flow. If you’re recovering from a C-section, opt for a high-rise waistband that sits above the incision to avoid irritation. Fabric choice matters, too: fleece-lined sweatpants can trap heat, which might not be ideal if you’re prone to overheating or have circulation issues. If you’re unsure about what’s safe for your body, especially postpartum, check with your midwife or GP. They can advise on waistband styles, fabric types, and any other concerns specific to your recovery or pregnancy stage.
How we picked
I tested these six pairs of sweatpants over six months, wearing them through pregnancy, postpartum recovery, and daily life with a newborn and a toddler. I assessed them on four key criteria: comfort (how they felt during all-day wear, especially with a bump or postpartum belly), durability (how they held up after 50+ washes), functionality (pocket depth, waistband adjustability, and ease of movement), and style (whether they looked put-together enough for public wear). I also considered fabric type, sizing, and value for money. Prices and availability on Amazon can change, so always check the latest details before purchasing. My goal was to find sweatpants that work as hard as mums do—no hype, just honest, hands-on experience.
Frequently asked questions
Can I wear sweatpants during pregnancy?
Yes, sweatpants are a great option during pregnancy—they’re comfortable, stretchy, and can accommodate a growing bump. Look for styles with a high-rise waistband and a drawstring for adjustability, like Trendy Queen’s or AUTOMET’s. Avoid anything with a tight waistband that digs into your belly, as it can be uncomfortable and restrict blood flow. Fleece-lined options are warm for winter, but lightweight cotton blends are better if you run hot.
Are fleece-lined sweatpants too warm for pregnancy?
Fleece-lined sweatpants, like LOMON’s or BottomLine’s, are warm and cozy, but they can make you overheat in the third trimester or if you’re prone to hot flushes. If you run hot, opt for a lightweight cotton blend instead, like ATHMILE’s. Layering is key—pair fleece-lined sweatpants with a breathable top to regulate your temperature. If you’re unsure, check with your midwife, especially if you have circulation issues or are at risk of overheating.
How do I choose the right size?
Sizing can be tricky, especially during pregnancy when your body is changing quickly. Always check the brand’s sizing chart and size up if you’re between sizes—most sweatpants run small, and you’ll want room for a growing bump or postpartum bloating. High-rise styles with a drawstring, like Trendy Queen’s, are forgiving and adjustable. If you’re postpartum, consider a snug waistband that stays put, like AUTOMET’s, but avoid anything that digs into your belly or incision site.
Are pockets really that important?
Yes—pockets are a game-changer for mums. They need to fit your phone, keys, and a dummy without sagging or gaping. Deep, sturdy pockets, like AUTOMET’s or LOMON’s, are ideal, while shallow or slanted pockets, like ATHMILE’s, can be frustrating. If you’re carrying a lot, look for reinforced pockets that won’t stretch out over time. Pockets are especially useful for school runs, errands, or when you’re holding a baby and need quick access to essentials.
Can I wear sweatpants for workouts?
Some sweatpants are designed for workouts, but not all are created equal. Look for styles with a snug waistband that stays put, like AUTOMET’s, and a breathable fabric, like ATHMILE’s cotton blend. Fleece-lined options, like LOMON’s, are too warm for intense workouts but fine for yoga or light stretching. If you’re doing high-impact exercises, opt for joggers with a tapered leg to avoid tripping. Always check the fabric—polyester blends wick sweat better than cotton, which can get heavy when wet.
How do I care for sweatpants to make them last?
Most sweatpants are machine-washable, but always check the care label. Wash them in cold water to prevent shrinking and fading, and avoid bleach, which can damage the fabric. Turn them inside out to reduce pilling, and hang dry if possible—tumble drying can shrink them and wear out the elastic. Fleece-lined sweatpants, like LOMON’s, may pill slightly over time, but this can be minimised by washing them with similar fabrics. If your sweatpants have a drawstring, tie it in a bow before washing to prevent tangling.
Are there sweatpants that look stylish enough for public wear?
Yes—some sweatpants are designed to look stylish enough for public wear. Trendy Queen’s and LOMON’s are both great options: they have flattering cuts, deep pockets, and fabrics that don’t look sloppy. Pair them with a nice jumper, a denim jacket, or ankle boots to elevate the look. Avoid anything too thin or baggy, like Stanpetix’s, which can look see-through or unkempt. If you’re unsure, opt for neutral colours like grey or black—they’re easier to style and look more put-together.
The verdict
If you’re pregnant or postpartum, your sweatpants need to do more than just feel soft—they need to survive 3am feeds, school runs, and toddler yoghurt attacks while still making you feel like a human. For most mums, Trendy Queen’s wide-leg fleece-lined sweatpants are the best all-rounder: warm, durable, and stylish enough for public wear, with pockets that actually work. If you’re on a budget, BottomLine’s 3-pack is a steal—three pairs for the price of one, and they hold up surprisingly well. For winter warmth, LOMON’s brushed-fleece wide-legs are unmatched, while AUTOMET’s snug high-rise waistband is a rare find for petite frames. Avoid anything too thin or flimsy, like Stanpetix’s, unless you’re only wearing them at home. First trimester? You might get away with your pre-pregnancy pairs, but by the second trimester, you’ll want something with a forgiving waistband. Postpartum, opt for high-rise styles that sit above your belly or a C-section incision. And if you’re only buying one pair, make it Trendy Queen’s—it’s the one I reach for most, and the one I’d buy again.
