How to choose the right snowboard trousers

Every session on the slopes deserves kit that lives up to your ambitions. Often playing second fiddle to the board itself, snowboard trousers are actually a key component of your setup. They directly dictate your comfort, your protection against the elements, and your freedom of movement.

Constantly exposed to snow, wind, and wet conditions, they must remain waterproof while wicking away the sweat generated by your effort. A poorly chosen pair quickly leads to discomfort or restricted mobility. Conversely, the right trousers allow you to stay dry, maintain the right temperature, and stay fully focused on your riding.

Understanding the 3 essential technical criteria

Three technical factors determine the efficiency of snowboard trousers: waterproofing, breathability, and insulation. Finding the right balance between them ensures comfort depending on the conditions and the intensity of your riding.

Waterproofing: lasting protection against snow Waterproofing, expressed in millimetres of water column, indicates the fabric’s resistance to moisture penetration.

• 5,000 mm: Sufficient for dry weather and occasional riding.
• 10,000 to 15,000 mm: A versatile level, suitable for frequent falls and long days on the hill.
• 20,000 mm and above: Recommended for backcountry missions and harsh weather conditions.
• Technical membranes (like Gore-Tex or proprietary equivalents) ensure durable waterproofing over time.

Breathability: avoiding internal moisture Breathability measures the fabric’s ability to let sweat escape (measured in g/m²/24h).

• 5,000 g: The minimum acceptable for moderate riding.
• 10,000 g and above: Recommended for intensive riding or milder temperatures.
• 20,000 to 25,000 g: Ideal for splitboarding, park laps, or spring sessions.
• Good breathability maintains a stable internal climate and prevents overheating.

Insulation: adjusting warmth to your riding Insulation depends on the type of trousers and your personal sensitivity to the cold.

• Shell (uninsulated): Highly versatile as you can adjust warmth with base layers.
• Light insulation (40–80 g): A good compromise for the majority of riders.
• Heavy insulation (100 g+): Suited for intense cold or long periods of inactivity.
• Excessive insulation can actually hinder comfort by causing you to overheat rapidly.

Which fit suits your riding style?

The “Regular” fit

The regular cut offers the perfect balance between a tailored look and ease of movement. It follows the body’s lines without being restrictive and suits the majority of body shapes.

• Versatile: Perfect for piste cruising, carving, and your first powder runs.
• Roomy: Offers enough space for impact protection and base layers.
• The “Go-To” Choice: Ideal as a single pair of trousers for varied use across the mountain.

The “Slim” fit

The slim cut sits closer to the body, focusing on style and precision.

• Adapted to: Carving and piste freestyle.
• Streamlined: Offers an increased feeling of control and less wind drag.
• Comfort check: Best chosen with stretch panels at the knees and hips.
• Tip: Check the fit with your protection on to ensure your movement isn’t restricted.

The “Relaxed” / “Baggy” fit

The loose cut prioritises comfort and total freedom of movement.

Safety tip: Look for a tapered cut at the ankles (or elasticated cuffs) to prevent the fabric from snagging on your bindings.e fuselée aux chevilles afin de ne pas accrocher les fixations.

Excellent for: Freeride and deep powder.

Layering friendly: Compatible with bulky protection and multiple layers.

Airflow: Naturally more breathable due to increased air circulation.

The details that make the difference on the slopes

Taped seams: the ultimate leak protection

Seams are the most vulnerable points for water entry. Technical models use heat-sealed (taped) seams to completely block water from seeping through the stitching holes.

• Simple check: The tape should be firmly glued down, without bubbles or peeling edges.
• Critical zones: Always protected on the crotch, knees, and seat (bum).
• High-end models: Feature fully taped seams for total waterproofing.

Ventilation zips: regulating your temperature

Ventilation openings transform your trousers into a personal air-conditioning system. These strategically placed zips allow you to dump excess heat rapidly without having to take your kit off.

• Most effective placement: Inner thighs (inseam).
• Ideal length: 15 to 20 cm.
• On technical models: Look for waterproof zips to maintain the shell’s integrity.
• Essential: For splitboarding, hiking the park, or riding on mild spring days.

Snow gaiters: an essential barrier

Gaiters prevent snow from working its way up inside your boots, even in deep powder.

• Fit: A good gaiter should sit high on the boot shaft.
• Integrated gaiters: Offer maximum protection and a continuous seal.
• Removable gaiters: Provide more versatility, but check the fastenings are secure.

Jacket-to-trouser connection system: stronger together

Connection systems link your jacket to your trousers to prevent snow from getting in at the waist, effectively creating a onesie seal.

• Compatibility check: Be careful if mixing brands, as zips and loops may not match.
• Fastenings: Zips, poppers (snaps), or loops depending on the brand.
• Best for: Deep powder days and high winds.
