W-Series Alpine Suit
The W-Series pants/suit for alpinism in extreme high-altitude activities. Ready for the cold? Our W-Series Alpine Suit pants feature an insulated bottom/legs and a top made from Polar Stretch Grid® fabric in the form of overalls, providing you with extra warmth. The top has two pockets, which, when combined with other pieces from the W-Series collection, allow you to keep everything accessible in the chest area, protected from the cold even while wearing a harness. The Kevlar fabric on the knees, lower legs, and back ensures durability against abrasions from rock/ice.
The outer fabric offers excellent wind and rain resistance (PFC-Free), and when combined with the Sorona® bio-synthetic fill panels (160 gr/m2), it guarantees thermal protection and optimal breathability. Pair it with other items from the W-Series collection to discover the lightest and most functional way to tackle the mountains. Ideal to wear over the W-Series Merino Base Layer t-shirt. Combine it with the W-Series Waterproof Shell Pants for the perfect combination of cold protection and waterproofing. Designed for very high-altitude activities in extremely cold temperatures.

Technology
The STORMFLEECE™ PRO fabric uses a patented technology from Singtex® to create a single-layer fabric (without a membrane) that is capable of withstanding wind and rain, while also offering excellent thermal insulation, high breathability, durability, and a very soft touch. STORMFLEECE™ PRO fabric is made by combining techniques and its innovative construction allows the fabric to leverage the strength and flexibility of the fibers while significantly reducing material consumption. Its densely woven structure minimizes fiber and thread waste, resulting in a unique fabric with a resistant exterior feel and a soft interior.
The OS2O FAST&LIGHT line powered by STORMFLEECE™ PRO enables the development of lightweight, durable, and technical single-layer products. Fabric developed under the BLUESIGN® System Partner.
