Mountain Warehouse Cloud Kids Snowsuit Review: a practical one-piece for real winter play

I bought the Mountain Warehouse Cloud Kids Snowsuit in light purple (printed) for a 7-year-old who spends a lot of time outside in winter – school runs, sledging, and the odd ski day. I wasn’t looking for something fancy, just something that kept her dry and warm without falling apart after two weekends. After a few weeks of use in cold, wet weather, I’ve got a decent idea of its strengths and weak points.

The first thing I noticed is that it feels like proper ski gear, not a flimsy costume-style suit. It’s reasonably light in the hand but not thin, and the fleece lining in the upper body gives a bit of immediate warmth when you put it on. We’ve used it in temps around 0°C down to about -6°C with wind, plus the usual British slush and wet snow, so it’s had a fair test already.

In day-to-day use, the main advantage is simply not having to worry all the time. She can roll in snow, sit on wet slides, crawl around making snowmen, and I don’t end up with a soaked, shivering kid after 20 minutes. The one-piece design helps a lot with that – no gap between jacket and trousers, no snow going down the waistband when they inevitably fall over.

It’s not perfect though. It takes a bit more effort to get on and off compared to separate jacket and pants, and toilet breaks are clearly less convenient. Also, while the waterproofing is good, this isn’t some extreme Arctic expedition suit – if your kid stands or kneels in slush for ages, you can eventually feel the cold get through. But overall, for normal winter use, it does the job pretty well.

On value, I’d put this snowsuit in the “good but not dirt-cheap” category. It’s clearly more expensive than the basic supermarket or discount store snowsuits, but you can also see and feel where the extra money goes: proper taped seams, reinforced knees, snow gaiters, and a decent fleece lining. You’re getting something closer to real ski gear rather than just a padded, water-resistant overall.

Compared to higher-end ski brands, you’re paying less, and of course you’re not getting all the extra features and top-level fabrics. But for a child who will outgrow it in one or two winters, I don’t see the point in spending top-tier prices unless you live in extreme conditions or ski every weekend. This strikes a sensible middle ground: the kid stays warm and dry, and you don’t wince every time they slide over gravelly snow.

If you only need a suit for one short ski trip or a couple of snow days per year, it might feel like overkill compared to a very cheap option. But if your kid is outside a lot in winter – school runs, forest walks, sledging, random playground time in slush – then the extra durability and waterproofing pay off. You’re less likely to end up buying a replacement mid-season because the first one leaked or tore.

Overall, I’d say it’s good value for money for active kids in regular winter use. Not a bargain-bin steal, but you get a proper functional snowsuit that actually does its job and seems built to last at least a full season of abuse, probably more. If your budget is tight and the child barely sees snow, you could go cheaper. If you care about them being genuinely dry and comfortable outside for hours, this is a sensible spend.

Design-wise, it’s a mix of kid-friendly and parent-practical. The light purple printed version looks fun without being too loud. My kid liked the pattern straight away, which honestly matters, because if they hate the look, they’ll fight you every morning. It’s not overly bulky, and the elasticated waist gives it a bit of shape so it doesn’t hang like a sack. From a parent’s side, the key design elements are the full front zip, elastic cuffs and ankles, and the hood that actually stays on reasonably well.

The hood is fleece-lined and big enough to go over a beanie, but not so huge that it keeps falling over the eyes. It doesn’t have a ton of adjustment, but for a kids’ suit it’s fine. The cuffs are elastic and work well with gloves – we tuck the gloves under the sleeves and snow doesn’t get in easily. The leg cuffs with inner snow gaiters are one of the better bits of the design: once they’re in place over boots, they hold well and really help keep feet and socks dry.

There are reinforced panels on the knees, which is important because kids don’t walk in snow, they kneel and crawl. After several sledging sessions and a lot of kneeling to build snowmen, the fabric on the knees still looks fine, no obvious wear or snagging. That’s a good sign, because cheaper suits often start to look tired there very quickly. The placement of the two front pockets is practical – high enough that snow doesn’t constantly pack into them, but low enough for small hands to reach easily.

If I had to nitpick the design, I’d say it could use a bit more reflective detailing for dark winter afternoons – there is some, but I wouldn’t mind more. Also, there’s no separate pass pocket or inner pocket, which matters more if you take them skiing, less so for everyday use. Overall though, the design is pretty straightforward: not flashy, but thought through from a “real child rolling in snow” point of view.

Comfort-wise, my test subject (7-year-old, average build) didn’t complain much, which is already a good sign. The suit in size 7–8 fits as expected: there’s a bit of room for layering, but it doesn’t drown her. The elasticated waist helps keep the bulk under control so she can still move easily. She can run, climb on sledges, and crouch without feeling restricted. The fabric has a bit of give, not stiff like some cheaper waterproof gear.

The fleece lining in the upper body makes it nicer to put on when it’s cold – no icy-feeling fabric on bare necks. She wears a long-sleeve base layer and sometimes a thin sweatshirt underneath. With that setup, she’s been comfortable down to around -5/-6°C while being active. If she’s standing still for a long time, you start to notice the cold a bit, but that’s more about layering than the suit itself. The legs are not fleece-lined, but with thermal leggings and ski socks, she hasn’t complained about cold legs.

One thing to keep in mind: like all one-piece suits, bathroom breaks are annoying. You have to unzip and basically half undress the child, which is not ideal in cold toilets or when they leave it to the last second. That’s not a fault of this specific model, just a reality of one-piece designs. Zips do move smoothly though, so you’re not fighting the suit on top of that.

She also likes that it’s not too heavy. Some bulkier suits make kids feel like they’re wearing armor; this one seems to hit a decent balance between warmth and freedom of movement. No rubbing or chafing spots so far, even around the neck and underarms. The cuffs and ankles are snug but not tight, and the hood doesn’t dig in or pull oddly when she turns her head. Overall, from a comfort and fit angle, it’s pretty solid for everyday winter use.

The snowsuit is 100% polyester, both outer and lining, which is standard for this type of gear. The outer fabric has that typical slightly textured ski-jacket feel, not the shiny shell you get on really cheap rainwear. It’s listed as waterproof with taped seams and a breathable membrane. In practice, that means we’ve had no leaks in normal use: snow, slush, and a bit of drizzle just bead off. I’ve checked the inside after wet play and the inner layers stay dry, including around the seams.

The fleece lining on the hood, collar, and upper body is soft and reasonably thick without being sweaty. It’s not the thickest fleece ever, but for an active kid it’s enough – they generate their own heat pretty fast. The lower part (legs and lower torso) is a smooth polyester lining, which is easier to slide over base layers and doesn’t trap moisture the same way fleece would if it got damp. For insulation, it’s more of a medium-weight suit. You still need proper base layers and warm socks on very cold days, but that’s normal.

Stitching and finishing are better than I expected for the price. Seams are neat, no loose threads hanging everywhere, and the taped seams inside are tidy. The zippers feel solid and haven’t snagged so far, even with a kid yanking them up and down. The leg zips are especially useful for getting the suit over bulkier boots. The elastic at the waist, wrists, and ankles is strong enough to hold but not so tight it leaves marks on the skin.

The care instructions are a bit fussy – 30° delicate wash, no softener, use re-proofer, tumble dry low. That’s fairly standard for waterproof gear, but you do have to actually follow it if you want the waterproofing to last. After the first wash (following the instructions), the fabric behaved the same, no obvious loss of water beading. Overall, the materials feel like proper outdoor gear, not toy-level fancy dress. There are more high-end fabrics on the market, but for kids who outgrow things in one or two seasons, this level is more than enough.

Durability is always a big question with kids’ gear, because they’re not gentle. After a few weeks of fairly heavy use – playgrounds, sledging hills, rolling in icy patches, and sliding on their knees – the snowsuit is holding up well. The reinforced knees are doing their job: no thinning, no scuffs deep enough to worry about, and the stitching around that area still looks solid. That’s usually the first area to go on cheaper suits, so it’s a good sign.

The bum area, which gets a lot of abuse from sitting in wet snow and on rough sledges, also looks fine. No obvious wear or fading yet. Zippers are still smooth and haven’t started catching or losing teeth. The pull tabs feel decent, and my kid can manage them herself with gloves on most of the time. Elastic at the cuffs and waist hasn’t stretched out or gone baggy after repeated use and one wash.

Speaking of washing, we followed the care instructions: 30°C delicate, no softener, low tumble dry. After that, the fabric didn’t shrink or warp, and the waterproofing still seemed to work – water still beads on the surface. You probably will need to use a re-proofer spray after a season or two if you’re using it a lot, but that’s standard for any waterproof garment, not a drawback of this one in particular.

Obviously, I can’t speak to multi-year use yet, but based on the build quality and first weeks of wear, I’d expect it to last at least through one full winter of regular use, probably two, assuming the child doesn’t outgrow it first. If you’re passing it down to a younger sibling, I think it would still be in usable shape, especially because of those reinforced high-wear areas. It’s not bulletproof, but it feels tougher than the budget supermarket suits we’ve tried before.

This snowsuit is a one-piece, full-length kids’ ski-style outfit with a hood, long sleeves, and cuffed legs. The model I picked is the light purple printed version in size 7–8 years. Out of the bag, it looks like standard mid-range ski gear: not cheap and flimsy, but also not heavy-duty mountaineering kit. The weight is around 0.8 kg, so it’s not a brick, and my kid could carry it herself easily.

On the practical side, it has a front zipper that goes down far enough to get in and out without a wrestling match, plus two zipped pockets at the front. Those pockets are actually usable – big enough for gloves, a snack, or a small toy, and the zips feel solid. There’s an elasticated waist built in, which is meant to stop it looking like a big bag and keep the warmth in. There are also zips on the lower legs to get them over ski boots or chunky snow boots, and inner snow gaiters that cling to the boots so snow doesn’t go up the leg.

The brand pushes the waterproof and breathable angle, with taped seams and a membrane. In real life, that just means you can send the kid out into wet snow and light rain without panicking. The upper body and hood are fleece-lined, while the lower part is just a normal smooth lining, which makes sense since the legs tend to get wetter and you don’t want fleece soaking up water inside.

For the price point (it often sits well below high-end ski brands), the overall package is pretty solid: proper taped seams, snow gaiters, reinforced knees, and a tested rating down to -10°C. I’d say it feels like a mid-range ski shop item rather than a supermarket budget suit. You’re not getting bells and whistles like fancy ventilation zips or high-tech insulation, but you’re getting the basics that matter for kids: warmth, dryness, and enough adjustability to last a season or two.

In terms of doing what it’s supposed to do – keeping a kid warm and dry – this snowsuit does a good job. We’ve used it in wet snow, light rain, and dry cold conditions. The waterproofing is the standout part: snow just slides off, and I haven’t seen any obvious soaking through on the shoulders, bum, or knees, even after sitting on a wet sled for a while. Taped seams help here, and you can tell it’s not just “water-resistant” marketing talk.

For warmth, I’d call it medium to warm. The brand mentions thermal testing down to -10°C, but that’s in a lab and assumes decent activity and layers. In real life, with base layers and the kid running around, it’s perfectly fine around -5°C to 0°C. Below that, you’d want to make sure they have good thermals and maybe a thicker mid-layer on the coldest days. It’s not a super thick, bulky suit, which I actually prefer because kids overheat quickly when they’re active.

Breathability is always tricky with kids because they sweat a lot when they move. After an hour of solid sledging and running uphill, she was warm and a bit sweaty, but not soaked inside. When I checked her base layer at home, it was damp but not dripping, which is about what I’d expect from a mid-range waterproof suit. No obvious condensation build-up inside the fabric, and she didn’t complain about feeling clammy while wearing it.

Snow gaiters and the one-piece design really help with overall effectiveness. We had no snow going up the back, no icy patches around the waistband, and socks stayed dry most of the time thanks to the gaiters gripping the boots. Compared to using a separate jacket and salopettes combo we had before, there were fewer “Mum, I’ve got snow in my pants” moments. So in practice, it’s effective enough that you can relax a bit while they thrash around in the snow.
