Ski and mountaineering pants Millet Trilogy Icon GTX Pro PT — waterproof breathable membrane, size L, black

Millet Trilogy Icon GTX Pro PT are technical ski and mountaineering pants engineered for alpine environments. Constructed with a waterproof, breathable membrane, these black size L pants are designed to protect against wind, snow and light rain while allowing moisture vapor to escape. The articulated cut supports freedom of movement during climbing, skinning or steep descents, and the design accommodates layering for variable conditions and prolonged use at altitude.

Advantages

These pants combine membrane waterproofing with breathability to maintain comfort during high-exertion activities. Reinforced areas and a tailored, articulated fit increase durability and mobility where it is needed most. The trousers are compatible with ski boots and mountaineering footwear, and their technical construction reduces bulk while preserving thermal performance when layered. The simple black finish offers low-visibility and easy pairing with technical outerwear.

Suitable for

• Ski touring and backcountry skiing
• Alpine mountaineering and glacier travel
• Winter hiking and approach routes
• Rope teams and mixed climbing where weather protection is required

Key specifications

• Waterproof, breathable membrane construction
• Articulated cut for enhanced mobility
• Layering-friendly fit compatible with insulating mid-layers
• Reinforced lower legs and high-wear zones
• Integrated gaiter-compatible openings at the hem
• Black technical fabric with matte finish
• Available in size L

How to use

Put the pants on over base and insulating layers to create an effective clothing system for alpine conditions. Adjust fit at the waist and secure leg hem closures before engaging in uphill travel or descents to prevent snow ingress. Use them together with a waterproof shell or insulated jacket depending on temperature and activity intensity. After exposure to wet or salty conditions, rinse and dry according to care instructions to maintain membrane performance.

Usage recommendations

For sustained high-output activities choose minimal insulation underneath to maximise breathability; for cold or static periods add an insulating mid-layer. Regularly check and clean reinforcements and hem areas to prolong service life, and pair the pants with compatible gaiters or boot interfaces when traversing deep snow or glaciers.
