Norrøna Bitihorn Alpha Hoodie Shirt (M)
The idea for the Bitihorn Alpha Hoodie Shirt from Norrona is to give multiple functionality in one product, developed in collaboration with mountain guide Giuliano Bordoni for use in high intensity activities from trail running, through to mountaineering. It could be an outer layer in the right conditions, but functions perfectly as a mid-layer or a base layer.
It’s a mixture of a lot of different fabrics, with a PFC-free DWR treated wind shell on the front made of recycled Pertex with breathable Polartech Alpha active insulation inside for exceptional breathability, compressibility and dry times via high loft fibers. Polartec Power Dry, a very lightweight grid polyester that dries out really quickly is in the hood, back and sleeves, wicking moisture vapour away from the inside and reduces the overall fabric mass and weight. Norrona have used a stretch fabric in the arms and cuffs to give unrestricted mobility and Polartech Powerwool, a baselayer fabric which contains wool, under the arms so it dries really quickly and has low smell.
Features include a built-in facemask for full-face protection, a hood for when it gets really cold and and windy, a deep two-way front zip with venting possibilities, one zippered chest pocket and stretch cuffs with thumb loops to act as hand gaiters. And the hem is made in two layers like a gaiter or snow skirt to tuck inside pants to keep snow out and to prevent the hem from riding up when active or under a harness. The logo on the chest is reflective to keep you visible in the dark.
Perfect for early mornings trekking down in the valley, biking or running in the foothills, climbing and hiking in the mountains, providing protection no matter what the conditions.

Bluesign Certified Fabric
A highly efficient insulation fabric, which is based on the Polartec® Thermal Pro® High Loft technology platform. This technology is uniquely suited to create warmth without weight, and exceptional breathability, compressibility and dry times via high loft fibers in a low density knit. Current market synthetic insulating materials are not breathable enough to handle the ”go” phases of most backcountry pursuits so additional layers need to be carried when resting or temperature drops. Polartec® Alpha excels at providing comfort for users on the move.
Polartec® Power Wool™
A design breakthrough for combining the distinct advantages of natural and synthetic fibers in a bi-component fabric. By isolating a merino wool interior and a synthetic fiber exterior Polartec® developed a hybrid fabric to optimize wicking, breathability, odor resistance and durability.
Incredibly fine yarns, precisely woven to provide a very lightweight yet strong and durable fabric. Its softness allows synthetic insulation to fully loft, while preventing leak through the face. The fabric is windproof.
Polartec® Power Grid™
By constructing a symmetrical grid pattern Polartec were able to not only increase thermal warmth and mechanical wicking capabilities, but actually reduce the overall fabric mass and weight. Benefits of products using the Polartec® Power Grid® are fast drying, great breathability, lightweight and easy care.
