A reliable shelter, the Alpha parka jacket from outdoor experts Arc'teryx is designed for weather conditions that push you to your limits. Packable, in case the conditions shift, it utilises innovative GORE-TEX INFINIUM™ technology with ripstop grid panels, resisting abrasion and blocking out the rain and wind, while a generous down fill keeps you warm on the move. All the performance functionally is there, with a helmet compatible hood and dual hem adjusters to lock out the chill.
