In this article you'll find all the key features to consider when choosing your ski trousers. Ski trousers are designed to keep you warm and, above all, dry throughout your day on the slopes. In direct contact with the snow, they must be waterproof and breathable while providing comfort through their thermal insulation, which will keep you warm. Softshell-type trousers can be a good option if you're looking for comfort or greater freedom of movement. This two-dimensional weaving technique provides thermal insulation and a windproof effect while retaining flexibility and excellent breathability.
Choosing waterproof and breathable ski trousers
Waterproofing is measured in mm Schmerber: the higher the mm rating, the more effective the membrane. Look for a rating of 10,000 mm or above to stay dry in all conditions. The trousers must also have fully taped seams.
The breathability of a garment is essential: you start to feel cold when you're wet. Perspiration must therefore be efficiently wicked away. Breathability is measured in g/m²/24h: the higher the figure, the better the moisture transfer. Look for a rating of 8,000 g/m²/24h or above.

Optimal insulation for ski trousers
The Thinsulate™ Insulation material is used in the lining of trousers. It is made from very dense synthetic fibres, providing superior insulation.
The PrimaLoft® technology, featured on many products, delivers lightweight, breathable and warm garments. PrimaLoft® is a lightweight, warm, water-repellent synthetic fabric that retains all its technical performance even when exposed to moisture.
The small details for choosing your ski trousers wisely
Ventilation zips
To regulate airflow during exertion, it is advisable to choose ski trousers fitted with ventilation zips. Positioned on the sides of the thighs, they will help you maintain the right temperature at all times.
Snow gaiters
Integrated snow gaiters sit beneath your trousers. These are specially designed to prevent snow from getting inside your trousers, particularly during off-piste use in powder snow.
Reinforcements
For beginners and freeriders, a few strategically placed reinforcements at the seat, knees or lower legs can make all the difference in a fall.
Safety beacons
Off-piste enthusiasts can boost their safety by choosing ski trousers fitted with a RECCO-type locating beacon. These are beacons sewn inside the garment. They reflect the signal from rescue transponders at the resort, allowing you to be located more quickly if you are caught in an avalanche.
Matching your ski trousers to your discipline
For ALPINE SKIING
If you spend your days on the slopes, you'll need waterproof and breathable trousers. During this activity, there will be moments when you cool down — particularly on chairlifts. A pair of warm, well-fitted trousers is therefore recommended.
For FREERIDE SKIING
You'll need a thoroughly waterproof pair of trousers to keep you protected even when you spend your days in the snow. A resistant component and knee reinforcement will also be important to withstand abrasion from external elements (roots, branches, rocks, etc.). In terms of cut, go for a fairly relaxed fit to allow a full range of movement while skiing. For waterproofing, opt for a rating of at least 20,000 mm. For off-piste enthusiasts, if safety is a priority, you can choose ski trousers fitted with a RECCO-type locating beacon.
For SKI TOURING
Ski touring involves a great deal of effort on the ascent and somewhat less on the descent. That's why your trousers need to offer both good waterproofing and a very high level of breathability. On the other hand, they should not be too insulating. Due to the climbing phases, your ski touring trousers should not keep you too warm. A windproof component protects you from wind and the elements, especially on the descent. We also recommend external openings for ski touring, as they allow for better ventilation.
For SNOWBOARDING
At first, you'll spend quite a bit of time on your seat and knees. You therefore need trousers with reinforcement at those points to stay dry. And of course, your trousers need to be warm and waterproof. For powder enthusiasts, integrated gaiters are a welcome addition. They prevent snow from getting in during a fall, keeping you nice and warm throughout the day.
For CROSS-COUNTRY SKIING
Cross-country skiing is an endurance sport with significant fluctuations in body temperature. To avoid overheating or getting too cold while maintaining freedom of movement, opt for tights, which will keep you warm at the start of a session and then wick away perspiration during effort.
On sizing, beyond the standard men's or women's sizes, some brands offer different leg lengths to suit your height.
