Polygon Helios Hooded Jacket

Polygon Helios is an insulated belay jacket built to preserve body heat in severe alpine environments, whether you’re standing still to belay or enduring long rest in deep winter conditions.

Insulated with our original high-performance FINEPOLYGON®, it maintains loft and performance even when wet. Six layers are packed into the body and four into the sleeves, delivering generous warmth that resists heat loss from snow, ice, and prolonged inactivity.

The outer fabric is a supple yet durable 15-denier stretch nylon with water-repellent finish, allowing freedom of movement and easy layering over an outer shell. Every detail is designed for use with thick gloves, from the oversized zipper pulls to the wide cuffs that make on-off quick and simple.

Despite its robust insulation, Polygon Helios weighs only 450 g, keeping it light and packable. Ideal as a dependable belay parka, it also doubles as a cold-weather outer layer for winter tent camping or snow cave bivouacs.
