Gore-Tex Pro is a totally waterproof & highly breathable fabric which still maintains its strength & durability. The Beta LT has a hip length & ergonomic 3D patterning which provides an enhanced level of articulation & movement in a trim, athletic fit & is designed for all mountain activities where you need ultimate protection, maneuverability & minimum weight. This superb all-rounder is made with a very durable yet supple plain weave nylon N40p-X 3 layer construction for high tenacity with a soft feel. The Beta LT features the Arcteryx Storm Hood which is helmet compatible yet can be cinched down to fit your head without restricting vision & mobility.
