The Rab Positron Jacket has a hybrid construction with both boxwall and stitch through construction. The boxwall provides optimal warmth and is used through the torso, back and hood while stitch through is used in the arms and sides of the jacket, though still providing warmth it is used principally so movement is not restricted. Filled throughout with high lofting and warm 800 fill power European goose down the Positron is a superb choice for cold conditions where you need to be able to move. The Positron has a superb adjustable helmet compatible hood that incorporates a high face baffle for additional protection. The water resistant front zip is backed with an insulated baffle preventing heat loss.
Pertex Endurance fabric offers high levels of weather resistance with a hydrostatic of 1000mm ensuring snow and spindrift are easily shed. The internal Nylon ripstop is a lighter fabric, this allows the down to loft to its full potential providing maximum insulation.
Hydrophobic down is used to provide better performance in damp conditions. This is achieved by washing in a Nikwax coating in the early stages of production. This down is NOT waterproof, but will retain its loft for longer if it gets damp, and will dry faster.
