Extremely compressible and lightweight, this minimally featured alpine jacket serves as a superior emergency shell. GORE-TEX® Paclite® fabrication provides extreme breathability with waterproof and wind-resistance with minimum weight and pack volume. Designed with a specific GORE-TEX® membrane with a protective internal layer made of an oil-hating/carbon hybrid, no separate lining is required – making this shell lighter, smaller, and easier to pack away.
