Whether you're heading for the heights of the Himalaya or planning a polar expedition, the Positron Pro is a down-filled jacket with zoned construction to optimise warmth and mobility while minimising bulk, so you can endure prolonged exposure to very cold conditions.
Lightweight | Warm | Water-repellent | Mountain & Expedition
Designed for mountain and expedition use up to 6000m, the Positron Pro Jacket uses a Pertex Quantum Pro shell to provide protection from the weather and is filled with the highest quality 800FP down. Boxwall construction on the torso, hood and upper arms provides extra insulation on more exposed areas. Stitch-through construction on the underarms and side panels allows for increased mobility while reducing bulk, weight and packsize.
A two-way front zip with synthetic insulated baffle behind provides maximum warmth, and helmet compatible down filled hood has wired peak and face baffle. Concealed hood adjusters are easy to use with gloved hands. The Positron Pro is optimised to offer the perfect balance of mobility, comfort and protection in very cold conditions.
