The women's one-piece ski suit is back: how to choose yours
The one-piece ski suit never quite left the slopes, but it has returned in force. A women's ski suit gives a single clean line from neck to boot, and it seals the gap where snow usually gets in: the waist. Below: why the all-in-one is back, how one-piece and detachable suits differ, what to check before you buy and how to size one, followed by four of our women's one-piece ski suits with the figures from their data sheets. To see the full range, browse women's ski overalls.
Why the women's ski suit is back
Two reasons: style and warmth. The style comes from the 1980s, when bright, fitted all-in-one ski suits ruled the Alps. Today's versions keep the confidence of that look but swap shiny nylon for stretch fabrics and slimmer, 3D cuts.
The warmth is practical. A ski jacket and pant always leave a junction at the waist. When you fall, sit in powder or bend to fix a binding, snow finds its way in. A one-piece ski suit has no gap. It also traps warm air around the lower back and stomach, which is where many skiers feel the cold first on a chairlift.
One-piece ski suit or two pieces that detach?
Not every women's ski suit is a true one-piece. Some separate at the waist, so you can wear the top and bottom on their own. That changes how you use them.
- True one-piece. The cleanest line and the best seal against snow. You put it on in one go, so look for long zips and easy toilet access. Cloud Active, Cloud Fashion and Cloud Warm 2L sit here.
- Detachable at the waist. Looks like an all-in-one, but the top and bottom separate. Easier to put on, easier in the bathroom and more versatile: the top can go to lunch on its own. The Cloud Warm Down works this way.
What to look for in a women's one-piece ski suit
- Waterproof rating (mm). All four suits in this guide are rated 5,000 mm. That suits groomed runs, holiday weeks and drier snow. If you ski often in wet, heavy snow, a jacket and pant at 20,000 mm protect more: see our guide to matching a women's ski set.
- Breathability. A one-piece holds more heat than two pieces, so moisture needs to escape. Look for side vents or cuff zips, and for the breathability figure in g/m²/24h.
- Insulation. Goose down gives the most warmth for its weight and suits cold, dry days. Synthetic fills and fleece linings cope better with damp.
- Zips. A double front zip lets you vent from the bottom or the top. A split zip at the foot opening helps the leg pass over a ski boot.
- Toilet access. The first question everyone asks. Look for a hip release zip, a waist zip or a top that detaches. If a suit has none, you will need to unzip the front and slip out of the top half.
- Snow seals. Inner cuff stoppers, a snow skirt at the hem and thumb loops keep snow out at the wrists and ankles.

For the coldest days: Cloud Warm Down Ski Overall
Our down ski suit. The Cloud Warm Down is filled with 90% white goose down and 10% feather at 750 fill power, under a Microflash stretch shell (74% polyamide, 26% elastane; 5,000 mm, 5,000 g/m²/24h, JIS). A double front zip helps you vent, YKK zips close it and the top and bottom detach at the waist. Slim, ergonomic 3D cut, XXS to XL: the widest range for petite skiers. White, Black and Beige.
Warm and practical: Cloud Warm 2L Insulated Ski Overall
The Cloud Warm 2L places down padding at the front chest over a rocker fleece lining, in a WARMFLEX four-way stretch shell rated 5,000 mm and 5,000 g/m²/24h. A hip release zip makes toilet stops simple, a FIDLOCK waist adjusts the fit and cuff zips add airflow. Slim fit, XS to L, in Purple, White and Black.
Sculpted tailoring: Cloud Fashion Ski Overall
The Cloud Fashion follows the body with 3D tailoring and a magnetic waist buckle belt. The WARMFLEX shell is rated 5,000 mm and 5,000 g/m²/24h (JIS), with a fleece-lined interior, a detachable waist zip for easier dressing, a windproof skirt at the hem and thumbhole cuffs. XS to XL, in Blue and Red.
The most breathable: Cloud Active Ski Overall
The Cloud Active has the highest breathability of the four: 10,000 g/m²/24h, with 5,000 mm waterproofing (JIS), in soft WARMFLEX stretch. A Velcro waist and 3D fishbone support shape the waist, and a high neck with a large lapel blocks the wind. Leg and sleeve pockets, a built-in snow skirt and a split zip at the foot opening complete it. No dedicated toilet zip is described. Slim fit, XS to XL, in Black, Blue Surf and Lavender Purple.
Sizing a one-piece ski suit: height and torso
A women's ski suit must fit two lengths at once: your legs and your torso. A pant that fits at the waist can still pull at the shoulders if your torso is long.
- Check height first, then chest and hips. Compare all three with the size chart on each product page.
- Do the reach test. Raise both arms and bend forward. If the crotch pulls up or the shoulders feel tight, try the next size or a model that detaches at the waist.
- Sit down. On a chairlift the suit stretches over the seat and knees. Four-way stretch helps, but it should not feel tight when seated.
- Petite or tall. Size ranges differ: XXS to XL on the Cloud Warm Down, XS to L on the Cloud Warm 2L, XS to XL on the Cloud Fashion and Cloud Active.
If you are between sizes, ask us before ordering.
Women's ski suit or ski set: pros and cons
| One-piece ski suit | Ski set (jacket + pant) | |
|---|---|---|
| Snow at the waist | None: no gap | Possible, unless you wear a snow skirt or bib |
| Warmth around the lower back | Highest | Good, better with a bib |
| Toilet stops | Need a hip or waist zip, or a detachable top | Easy |
| Versatility | One look (unless it detaches) | Jacket and pant can be worn apart |
| Waterproofing in our range | 5,000 mm | Up to 20,000 mm |
| Sizing | Must fit legs and torso at once | Top and bottom sized separately |
Prefer two pieces with extra coverage? A bib pant is the middle ground: read ski bibs vs ski pants or browse women's ski pants and bibs. For two-piece suits sold as one, see women's ski suits.
Women's one-piece ski suits: frequently asked questions
How do you go to the toilet in a one-piece ski suit?
It depends on the suit. Look for a hip release zip (Cloud Warm 2L), a waist zip (Cloud Fashion) or a top that detaches at the waist (Cloud Warm Down). Without one of these, you unzip the front and slip out of the top half.
Is a one-piece ski suit warmer than a jacket and pants?
Usually, yes. A one-piece has no gap at the waist, so snow cannot get in and warm air stays around your lower back and stomach. The fill matters too: goose down is warmest for its weight on cold, dry days.
Are women's one-piece ski suits waterproof?
Ours are rated 5,000 mm, which suits groomed runs, holiday weeks and drier snow. For frequent skiing in wet snow, a jacket and pant rated 20,000 mm offer more protection.
What size one-piece ski suit should I buy?
Check your height, chest and hips against the size chart, then do a reach and sit test. If the suit pulls at the crotch or shoulders, go up a size or choose a model that detaches at the waist. Petite skiers can start with the Cloud Warm Down, which comes in XXS.
Can I wear a one-piece ski suit for après-ski?
Yes. Slim suits such as the Cloud Fashion and Cloud Active are designed to look good off the slopes too. A detachable suit lets you take off the top half and add a jumper or a light down jacket.
