Whether you're a hardcore skier or a casual enthusiast, kitting yourself out properly to hit the slopes is essential. Jeans or everyday trousers simply aren't suited to effective sport performance.
You may feel overwhelmed by the options when choosing your next pair of ski trousers. Check out our selection guide to find out the key criteria and parameters to look for in your next purchase.
Choosing your ski trousers based on materials
Your ski trousers are primarily designed to protect you from the cold and moisture of the snow. But they must also allow you to move freely and comfortably without 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 high-performance technologies that vary by manufacturer and brand. Very often, Softshell fabrics lined with fleece (to provide cosy warmth) are used. They have the particular advantage of being highly breathable, which is a clear benefit for managing perspiration during hours on the slopes.
What level of waterproofing do you need to stay dry?
The waterproofing 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-moisture conditions.
- Between 5,000 and 10,000 mm: Good protection against snow and moderate moisture — ideal for occasional skiers.
- 10,000 mm and above: Excellent waterproofing to handle tough conditions (snow, rain, wind).
For intensive use and optimal protection, it is recommended to choose trousers with a waterproofing rating of 10,000 mm. Some technical models can reach 20,000 mm, offering outstanding resistance to the harshest weather conditions.
Bear in mind that Softshell fabrics cannot be seam-sealed. Water may therefore seep slightly through the seams, but not snow. This makes them an excellent option for skiing, combining warmth and waterproofing.
Key features to look for based on your discipline
Each ski discipline has specific equipment requirements. Your choice of trousers must match your activity to guarantee comfort and performance.
Alpine skiing: prioritising thermal insulation and protection
Alpine skiing is typically practised on groomed pistes, where temperatures can be very 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 leg to protect the fabric from friction against ski shoes.
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 trousers that are lightweight, stretchy and breathable to efficiently manage perspiration. A model with side ventilation zips is recommended to better regulate body temperature. Opt for softshell fabrics with good water repellency and a windproof membrane, rather than a heavily insulating pair of trousers that risks overheating you during the effort.
Cross-country skiing: freedom of movement
Cross-country skiing is an endurance sport that places heavy demands on the lower body. Your trousers must therefore be highly stretchy and breathable to ensure optimal comfort. Softshell fabric models with a windproof front panel and a more breathable back panel 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.

Ski freeride: waterproofing and durability first
Freeride is practised off-piste, often in challenging conditions with deep snow and variable weather. For optimal protection, opt for trousers with a waterproof membrane, breathable and with a fabric resistant to abrasion. 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, getting the right garment size is crucial. Too tight and you'll be uncomfortable, restricted in breathing and movement. Too loose and you'll constantly be adjusting your trousers and suffer significant heat loss, or even moisture ingress. Your trousers should feel like they're not there when you're out on the mountain.
As a general rule, choose a size slightly larger than you would for everyday trousers and, above all, opt for trousers with an adjustable belt. The ideal option 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 inevitably ugly and badly cut are long gone. Today, reputable manufacturers pay 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.
And don't be afraid to stand out: we spend far too much time in grey skies not to treat ourselves to a colour that will pop against a snowy backdrop. It's also a great way to be seen and stay safe on the mountain!
Other parameters and accessories not to overlook
There are of course many construction details today that can make a real difference in day-to-day use. Below, we'll highlight what we consider the essentials — the ones 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 inevitably when you ski, you fall sooner or later! So don't hesitate to choose trousers with reinforcements in strategic areas. Many models today incorporate padding on the seat, shins and pre-shaped knees. This is a clear advantage and will also extend the longevity of your trousers by making them more resistant.
- Pockets: always go for zipped pockets… it'll stop you losing important items in the powder! And having a few extra pockets is always handy. Make sure you choose a garment that has plenty of 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 damp calves or wet feet after an hour or two of skiing.
- Vents: some trousers, designed more for intense skiing in fair weather, feature vents that optimise the breathability of your garment. Depending on your activity, this can be an interesting option to consider.
- Safety beacons: some manufacturers now equip their garments with safety beacons that make it easier to locate a person in distress. These small details are always extremely useful in an emergency. And they come at a very modest cost relative to the protection they provide!
Caring for your ski trousers to extend their lifespan
Proper care is essential to maintain the performance of your ski trousers season after season. Here are some practical tips:
Before washing
- Empty all pockets and close zips, velcro and buttons.
- Shake the trousers to remove any accumulated snow, mud or debris.
Washing
- Use a specialist waterproof membrane detergent and absolutely avoid fabric softener, which degrades the breathability of the fabric.
- Select a synthetic cycle at 30°C with a gentle spin.
- If your trousers are heavily stained, do 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 sunlight.
Re-waterproofing
- After several washes, the fabric's water repellency may diminish. To restore it, use a specific waterproofing spray.
- Spray the product over the entire surface of the trousers and leave to air dry or tumble dry on a low heat setting if the care label permits.
Repair
In the event of a small tear or abrasion, a waterproof and resistant repair patch can be used — ideal for extending the life of your kit.
Finally, match your budget to your level of use. You don't buy the same ski trousers for one relaxed ski week a year as you do for skiing every weekend for 4 months at a champion's intensity. There are now very wide ranges available, suited to all uses and meeting many different needs. CimAlp illustrates this perfectly, offering an extensive selection of ski trousers, all meeting the essential criteria we've outlined.
