Whether you're a dedicated skier or an occasional one, it's essential to kit yourself out properly to tackle the slopes. Jeans or everyday trousers simply aren't suited to effective sport performance.
You may well feel overwhelmed by the options available when choosing your next ski trousers. Check out our selection guide to find out which criteria and parameters to look out for when making your next purchase.
Choosing your ski trousers based on materials
Your ski trousers are primarily designed to protect you from the cold and moisture from the snow. But they must also allow you to move freely and comfortably without any restriction.
That's why it's essential to choose a material that is warm, waterproof, breathable, resistant and flexible. To achieve this, ski clothing specialists have developed highly effective technologies that vary by manufacturer or brand. More often than not, fleece-lined Softshell fabrics are used (to provide cosy warmth). Their key advantage is being highly breathable, which is a real asset for wicking away perspiration during hours on the slopes.
What level of waterproofness do you need to stay dry?
The waterproofness of ski trousers is determined by their Schmerber rating, which measures the fabric's resistance to a column of water expressed in millimetres.
- Below 5,000 mm: Limited protection, suited to dry or low-humidity conditions.
- Between 5,000 and 10,000 mm: Good protection against snow and moderate moisture, ideal for occasional skiers.
- From 10,000 mm upwards: Excellent waterproofness for tackling tough conditions (snow, rain, wind).
For intensive use and optimal protection, it is recommended to opt for trousers with a waterproofness rating of 10,000 mm. Some technical models can reach 20,000 mm, offering exceptional resistance to the harshest weather conditions.
Bear in mind that Softshell fabrics cannot be seam-sealed. Water may therefore seep in slightly through the seams, but snow cannot. They are therefore an excellent option for skiing to combine warmth and waterproofness.
Key features to look for based on your discipline
Each skiing discipline has specific equipment requirements. Your choice of trousers must match your activity to guarantee comfort and performance.
Alpine skiing: prioritise thermal insulation and protection
Alpine skiing is often practised on groomed runs, with temperatures that can be extremely low, especially at altitude. For optimal protection against the cold, choose ski trousers well insulated with a windproof and waterproof membrane. The ideal option is a model with a fleece lining that provides good thermal insulation while remaining breathable. Also consider reinforcements at the lower legs to protect the fabric from friction with ski boots.
Ski touring: lightweight and breathability first
Ski touring is a demanding discipline that requires intense physical effort on the ascent. It's therefore essential to choose lightweight, stretchy and breathable trousers to effectively wick away perspiration. A model with side ventilation zips is recommended for better regulation of body temperature. Opt for softshell fabrics with good water repellency paired with a windproof membrane, rather than a highly insulating pair of trousers that risks overheating you during exertion.
Cross-country skiing: freedom of movement
Cross-country skiing is an endurance sport that puts enormous strain on the lower body. Your trousers must therefore be highly stretchy and breathable to ensure optimal comfort. Softshell fabric models with a windproof face at the front and a more breathable face at the back are ideal for this discipline. It is also preferable to opt for close-fitting trousers or thermal tights so as not to restrict your movement.

Freeride skiing: waterproofness and robustness first
Freeride is practised off-piste, often in challenging conditions with deep snow and variable weather. For optimal protection, go for trousers with a waterproof membrane and breathable fabric and a friction-resistant fabric. A 3-layer pair of trousers with sealed seams and integrated gaiters will be perfect for tackling powder and extreme conditions.
Choosing the right size of ski trousers
When it comes to sport, choosing the right garment size is crucial. Too tight and you'll be uncomfortable, restricted in your breathing and movement. Too loose and you'll constantly be readjusting your trousers and risk significant heat loss, or even moisture getting in. Your trousers should feel like a second skin when you're out on the mountain.
As a general rule, choose a slightly larger size than you would for everyday trousers and, most importantly, opt for trousers with an adjustable belt. The ideal is an open belt with velcro: it allows for easy, quick and secure adjustment.
Style and colour
Treat yourself! The days of sports trousers being unavoidably ugly and badly cut are long gone. Today, any manufacturer worth their salt pays close attention to the style and cut of their garments. Without going full fashionista, it's important to feel good and project a positive image of yourself.
Don't be afraid to stand out: we spend far too much time in grey conditions not to treat ourselves to a colour that pops against a snowy backdrop. It's also a great way to be seen and boost your safety on the mountain!
Other parameters and accessories not to be underestimated
There are of course many construction details today that can make a real difference in day-to-day use. Below, we'll highlight those we consider essential and that should guide your choices. Then it's up to you to decide based on your own preferences and priorities!
- Reinforcements: it won't surprise anyone, but falling is an inevitable part of skiing sooner or later! Don't hesitate to choose trousers with reinforcements in strategic areas. Many models today feature padding on the seat, shins and pre-shaped knees. This is a real bonus and will also ensure the longevity of your trousers by making them more resistant.
- Pockets: always opt for zipped pockets… It'll stop you losing anything important in the powder! And it's always handy to have a few extra pockets. Make sure you choose a garment that's well equipped with them.
- Waterproof gaiters: gaiters provide an optimal seal at the bottom of your trousers and prevent moisture from creeping up. This is not a detail to overlook — there's nothing worse than ending up with a damp calf or wet feet after an hour or two of skiing.
- Ventilation: some trousers, designed more for intense skiing in fine weather, feature vents that optimise the breathability of your garment. Depending on your style of skiing, this can be a worthwhile option to consider.
- Safety beacons: some manufacturers now equip their garments with safety beacons to aid location in the event of an emergency. These small extras are always invaluable when you're in distress. And their cost is minimal compared to the peace of mind they provide!
Caring for your ski trousers to extend their lifespan
Proper care is essential to preserve the performance of your ski trousers season after season. Here are some practical tips:
Before washing
- Empty all pockets and fasten zips, velcro and buttons.
- Shake the trousers to remove any snow, mud or accumulated residue.
Washing
- Use a specialist waterproof membrane detergent and avoid fabric softener at all costs, as it damages the breathability of the fabric.
- Use a synthetic programme at 30°C with a gentle spin cycle.
- If your trousers are heavily stained, carry out a pre-soak with a mild soap.
Drying
- Avoid the tumble dryer, which can damage the technical membrane.
- Hang your trousers on a hanger and leave them to dry in the open air, away from direct heat sources such as radiators or direct sunlight.
Re-waterproofing
- After several washes, the fabric's water repellency may diminish. To restore it, use a specialist waterproofing spray.
- Spray the product over the entire surface of the trousers and leave to dry in the open air or at low temperature in a tumble dryer if the care label permits.
Repair
In the event of a small tear or abrasion, you can use a waterproof and resistant repair patch, ideal for extending the lifespan of your kit.
Finally, calibrate your budget according to how you ski. You wouldn't buy the same ski trousers for a relaxed week on the slopes once a year as you would for skiing every weekend for four months at a champion's intensity. Today there are very wide ranges, suited to every use and meeting a multitude of needs. You'll find a perfect example with CimAlp, which offers an impressive selection of ski trousers, all meeting the essential criteria we've outlined.
