The Beta Lightweight Jacket – our lightest Beta – is built for mountain realities. Highly versatile, it’s carefully designed to deliver complete waterproof, windproof, breathable protection without sacrificing lightweight packability. Its innovative GORETEX ePE membrane is light, strong, and PFC free. C-KNIT backer technology improves comfort and breathability. The helmet-compatible StormHood protects without compromising vision, pit zippers ventilate, and a RECCO reflector can aid in search situations.
