The Norrona Men's Trollveggen Flex1 Pants are designed to be your ultimate companion for demanding mountaineering and alpine adventures. These versatile, high-performance pants are perfect for a range of activities, from intense ski touring and mountaineering to trekking and general outdoor explorations.

Constructed from a 199 gr/m² flex1 softshell fabric, these pants combine superior stretch, durability, and windproofing with impressive breathability. The 90D 4-way stretch double weave in recycled nylon offers excellent movement and durability, while the additional robust flex1 fabric in the thighs, seat, and lower legs ensures extra protection where you need it most. Both fabrics feature a PFC-free DWR treatment for enhanced water resistance.

Key features include a Custom-fit waist system with velcro adjustment for a personalized fit, two zippered hand-warming pockets, and two thigh pockets with bellows—one equipped with a mobile pocket. The 3/4 side zips provide adjustable ventilation, while the gusseted lower legs and bootlace hook with eyelets ensure a secure fit over boots. The pants are also compatible with suspenders and a mountaineering zip-in bib for added versatility.

Performance:

• Windproofness (5/6): 100% windproof, these pants offer excellent protection against the wind in most conditions. They are slightly lighter and less rugged than the most extreme category, making them ideal for a range of alpine environments.
• Waterproofness (2/6): Treated with durable water repellent, these pants can handle small amounts of rain and light moisture but are not fully waterproof. They are designed to resist moisture but will require additional layering or re-impregnation for extended exposure.
• Insulation (1/6): These pants have no inherent insulating properties but work effectively over insulation layers to provide wind protection and maintain warmth in combination with base layers.
• Breathability (5/6): Designed for high-intensity activities, these pants offer excellent moisture transportation, quick-drying properties, and effective ventilation to keep you comfortable during strenuous climbs and treks.
• Durability (6/6): Built to last, these pants are made with extremely durable fabrics that withstand extensive use. They are designed for prolonged exposure to demanding conditions and can handle 150 days of active use.
• Lightweight (4/6): Balancing lightweight design with durability, these pants are ideal for those seeking protection without unnecessary bulk.
