CMP Boy's Ski Trousers Review: budget-friendly salopettes that keep kids warm and visible on the slopes

I bought these CMP boy's ski trousers (size 12 years) for a week in the Alps with my son, mainly because I didn’t want to spend a fortune on something he’ll outgrow in a year. I went in with pretty low expectations: they’re polyester, made in China, not a big fancy brand, and the price was reasonable compared to the big ski names. After a full week of daily use – lifts, falls, snowball fights, and the usual kid chaos – I’ve got a pretty clear idea of what they do well and where they’re just okay.

The first thing I noticed is that they feel like proper ski trousers, not those thin “snow pants” you get from supermarkets. The fabric has a medium weight, feels tough enough, and the salopette/brace-style top really helps keep them up, which is good because the waist fit is not perfect. My kid is fairly slim, and like one of the Amazon reviews said, they were a bit loose at the waist but stayed in place thanks to the braces. So straight away: not tailored, but practical.

On the slopes, they handled typical family-ski conditions: a mix of cold mornings, a couple of wet-snow afternoons, and a lot of sitting on lifts and in the snow. The 5,000 mm waterproof rating is not high-end, but for a kid who’s not skiing hardcore off-piste, it was enough. He didn’t come back soaked, even after rolling around in the snow and spending time in the beginner area where they sit a lot. Breathability is listed as 5,000 g/m²/24 h; I can’t measure that, but he never complained about being sweaty or sticky, even when the sun came out.

In short, these trousers are solid mid-range gear: not premium, not junk. They get the job done for regular family skiing or playing in the snow. If you’re expecting pro-level waterproofing or a super tailored fit, you’ll be a bit underwhelmed. But if you want something that keeps a kid warm, dry, and easy to spot on the slopes without blowing the budget, they make sense. The rest of this review goes into the details: design, materials, comfort, performance, durability, and whether I think they’re good value for money.

For me, the main reason to buy these CMP ski trousers instead of a big-brand pair was price versus usage. My kid skis maybe one week a year, plus a few days of local snow play if we’re lucky. Dropping a lot of money on premium trousers for that level of use just doesn’t make sense. These CMP pants sit in that middle price bracket: more expensive than bargain-basement supermarket snow pants, but clearly cheaper than top-end ski brands. For what they offer, I think the value is good, not mind-blowing but solid.

Here’s what you’re paying for that feels worth it: proper waterproofing with taped seams, real insulation that keeps them warm, braces that stop them sliding down, snow gaiters, and edge protection. All the basics for a proper ski trip are there. You’re not paying for branding, flashy design, or advanced tech that your kid probably won’t fully use. And given the 4.6/5 rating from over 10,000 reviews on Amazon, it’s not just my experience – a lot of parents seem to think they hit the right balance.

On the downside, there are a few things that remind you this is mid-range gear: the 5,000 mm waterproof rating is fine but not top-tier, the fabric is all polyester with no fancy membrane, and the fit is a bit generic. If you need trousers that can handle very wet conditions or super-active kids who ski hard all season, you might want to invest more. But for standard holiday skiing, these do enough for the price.

Overall, I’d say the value is strongest if:

• Your kid skis 1–2 weeks a year max
• You want something better than supermarket snow pants but don’t want to pay premium-brand prices
• You’re okay with a straightforward, practical design

Design-wise, these CMP trousers are very much function first, style second, which I actually prefer for kids’ gear. The salopette style (with braces) is a big plus: kids bend, fall, and crawl in the snow, and normal waist-only trousers tend to slip down or expose a gap between jacket and pants. With these, my son never had that cold strip of skin at the back, even when he was sitting on the snow messing around with friends. The braces are adjustable and stayed in place all week – no annoying slipping.

The trousers have a flat front, straight leg cut. Nothing trendy or slim-fit here, but that’s probably better for layering and movement. At the bottom of the legs you get snow gaiters that hook over the boots and stop snow from getting in. These gaiters actually worked well: after a few falls and some off-piste messing about, his socks stayed dry, which is all I care about. There’s also edge protection on the inner cuffs – a tougher fabric area designed to resist cuts from ski edges. After a week, I could see a few scuffs but no tears, so that part seems to do its job.

In terms of features, it’s pretty minimal:

• 2 front zip pockets (no back pockets)
• Pull-on style with side adjustments and braces
• No vents, no fancy zips down the sides, no integrated belt

The colour options are a nice touch. The bright colours (like the neon orange mentioned in reviews) are practical for visibility – you can actually find your kid from a distance on a busy slope. My Black/Blue version is more low-key but still fine. If I had to nitpick, the rise is marked as “low rise,” which is a bit weird for kids’ ski gear. With the braces, it’s not really an issue, but if your kid hates wearing braces, the waist alone might feel a bit low for deep snow days.

From a comfort point of view, my son had no real complaints, which is already a good sign. He wore these trousers every day for a week, usually from about 9 a.m. to 3–4 p.m., with just a thermal base layer underneath. He could bend, sit, and fall without feeling restricted. The straight leg and standard fit give enough room to move without feeling like a balloon. There’s no inner scratchy seams or weird rubbing points that he mentioned, which is important when kids are in them for hours.

The braces are the real comfort win here. Because the waist is a bit loose (like several reviews noted), the braces do all the work of holding the trousers up. That means no constant pulling them up and no cold gap between trousers and jacket. The inside of the waistband is fairly plain – no plush fleece or anything – but he never complained about itching. The trousers are also not heavy; at around 0.5 kg, they’re light enough that kids don’t feel weighed down.

Temperature-wise, they hit a good middle ground. On the colder days (around -5°C with some wind), he was fine with a single thermal layer underneath. On the warmer day (slightly above 0°C and sunny), he did say he felt a bit warm in the afternoon, but not to the point of wanting to take them off. There are no ventilation zips, so you rely on just opening the jacket and moving slower if they overheat. For most family trips, I think that’s acceptable, but if your kid runs hot or skis very actively, that could be a minor downside.

The only real comfort downside is the fit inconsistency. If your kid is slim, expect the waist to be loose. If they’re tall for their age, you might need to size up for length, at the risk of even looser waist. It’s manageable with the braces, but it’s not a tailored fit. Overall, though, once you get the right size, day-to-day comfort is pretty solid, and my son never asked to change out of them early, which says a lot.

The trousers are 100% polyester inside and out: shell, lining, and insulation. That’s pretty standard for this price range. You’re not getting any fancy membranes like Gore-Tex here, but CMP uses their own Clima Protect technology, which basically means a waterproof, breathable layer built into the fabric. On paper, you get 5,000 mm waterproofing and 5,000 g/m²/24 h breathability. In practice, that puts them in the “okay for normal use” category, not for heavy, wet snow all day long.

During our week in the Alps, we had one day of wetter snow and mild temperatures. After a few hours of sitting on lifts and kneeling in slushy snow, my son’s legs were still dry. I checked the base layer at lunch and at the end of the day: no obvious damp patches. That tells me the taped seams and fabric coating are doing their job, at least for typical family skiing. I wouldn’t trust them for spring skiing in constant rain, but for normal winter conditions, they’re fine.

The insulation is also polyester and classed as medium weight. It’s not super puffy, so don’t expect ultra-warm, Arctic-level insulation. But with a thermal layer underneath, my kid never complained of cold legs, even in minus temperatures and wind on the chairlifts. If anything, I’d say CMP struck a decent balance: warm enough without turning into a sauna when the sun comes out. Also, the fabric has medium stretch listed, but in reality it feels more like standard non-stretch polyester. Movement is more about the cut than the stretchiness of the fabric.

One thing to keep in mind: polyester like this will not age as nicely as high-end technical fabrics. It can get a bit shiny and scuffed over time. After one week, ours still look good – just a couple of light marks near the ankles where the skis rubbed. For a kids’ piece that will probably be outgrown in one or two seasons, I think the material choice is sensible, not fancy. If you want premium materials that last years and years, you’re looking at a very different price point.

Durability is always tricky with kids’ gear because they grow out of it so fast. After one full week in the Alps plus a couple of sledging days back home, these CMP trousers still look in good shape. The stitching is intact, the zips work smoothly, and the braces haven’t stretched out or twisted. The fabric at the knees and seat – the usual high-wear zones – shows no obvious thinning or pilling so far.

The only visible wear I can see is around the inner ankle area, where the ski edges sometimes rub. The reinforced edge protection fabric there has a few light scuffs, but nothing close to a cut or tear. That’s actually better than some cheap snow pants I’ve bought in the past, which started to fray badly after just a few days. So while the material is clearly mid-range polyester, the way CMP has reinforced the critical zones feels thought-through enough for normal use.

I can’t speak for multi-season durability yet, but based on what I’ve seen, I’d expect these trousers to last at least two ski trips for a single child, and probably still be in good enough condition to pass down to a younger sibling or cousin – assuming the sizing still works. They’re not the type of item you’ll keep in perfect condition for five years, but kids’ legs grow faster than the fabric will fail, which is the main point here.

If you compare them to more expensive brands, you’ll probably get better long-term durability and more resistant materials at the higher price points. But for the money, I’d say durability on these is honestly decent. They’re not fragile, nothing feels like it’s about to fall apart, and they cope well with the normal abuse a kid gives them: sitting on rough snow, falling, dragging skis, and general rough play.

In actual use on the slopes, these CMP trousers are reliable enough for typical kids’ skiing. The waterproofing held up against regular falls, sitting on snowy chairs, and general messing about in the snow park area. By the end of each day, when we took off his boots and layers, his legs were warm and dry. No soggy base layers, no complaints about cold thighs, even when the wind picked up higher on the mountain. For a 5,000 mm rating, that’s roughly what I expected: solid for snow, not for heavy rain.

Breathability is harder to judge, but I’ll say this: my son is not a pro racer, but he’s not just standing around either. He skis, he runs, he plays, and he never came back drenched in sweat. The lining doesn’t feel clammy, and when we hung them up overnight in the hotel room, they dried quickly. So for a kid-level activity level, the 5,000 g/m²/24 h spec seems enough. If you were doing intense ski touring, it would be another story, but that’s not what these are for.

In terms of movement and handling falls, the trousers did well. The edge protection on the inner cuffs took a few hits from the skis. I saw some scuffing but no holes, which is all I can really ask for after a week. The snow gaiters at the bottom worked properly – no snow sneaking into the boots, even after a couple of proper wipeouts in deeper snow. The straight leg fits over standard ski boots without a fight, and the fabric doesn’t cling or get stiff in the cold.

If I compare them to higher-end kids’ ski trousers from big brands I’ve tried before, you can feel the difference in technical performance. Those usually have better waterproof ratings, more breathable membranes, and extra features like vents or more pockets. But for the price bracket CMP is in, I’d say performance is better than basic supermarket gear and good enough for one or two ski trips a year plus some sledging days at home. They’re not built for season-long use by ski-club kids, but they’re fine for casual family use.

Out of the bag, these CMP boy’s ski trousers look like classic salopette-style ski pants: full-length legs, built-in braces, and a fairly simple, no-frills design. Mine are the Black/Blue combo, which is more practical than flashy, but the line also has brighter colours like neon orange, which matches what several Amazon reviews mention about kids being easy to spot. They arrive folded in a plastic bag, nothing fancy in terms of packaging, but honestly that’s fine – you’re paying for function, not unboxing theatre.

The model is called Kid Salopette 3W15994, and the label says 100% polyester for the shell, lining, and padding. There are two slit pockets on the front with zips, enough for a lift pass, a tissue, or a snack bar, but don’t expect tons of storage. The cut is straight leg, low-rise, with a standard fit, so it’s not super baggy but not tight either. My son could easily wear a thermal base layer and a thin fleece underneath without feeling squeezed.

One thing that’s worth noting: the size system is a bit confusing. The listing shows ages (like 12 years), but the physical label uses height in centimeters (e.g., 152). Several reviews mention sizing quirks – some say they run a bit small in length, others that waist is loose. In our case, the length for 12 years was fine for a 150 cm kid, with a bit of room to grow, but the waist was on the generous side. Luckily, the braces and side adjustments help, but if your kid is at the top of one size range, I’d consider going up.

Overall, in terms of presentation, it’s straightforward and practical: you get a pair of insulated, waterproof, bib-style ski trousers, with taped seams, snow gaiters at the bottom of the legs, and some reinforcement at the cuffs for edge protection. No fancy branding all over the place, no hidden gadgets. It looks and feels like solid mid-range gear meant for actual use, not for Instagram photos.
