Made for alpine travel and mountain realities, the Beta SL Jacket – our lightest Beta – is carefully designed to deliver complete waterproof, windproof, breathable protection without sacrificing features or packability. Its next-generation GORETEX ePE membrane is light, thin, 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.
This product is free of intentionally added PFAS.
The new ePE membrane technology is lighter and thinner, but just as strong and durable as the materials we used before. You may notice the face fabric “wetting out” slightly faster in products with ePE membranes, but rest assured this does not affect the waterproofing of the membrane itself. If you notice the fabric wetting out faster than you’d like, simply wash the jacket and dry it to remove the oil contamination and bring the DWR back to its full power.
Our trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably under outer layers.

Cut loosely through the waist, hip, and thigh for a casual fit.
Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
