We turned to professional guides, athletes and devoted backcountry recreationalists when designing the Sopris Pro 30. Made from Osprey's NanoFly (UHMWP) fabric, this best-in-class avalanche airbag pack is exceptionally durable and lightweight, making the grind up a skin track as painless as possible. Women's-specific sizing and fit is both efficient and safer when moving in the mountains. The included Alpride E1 electronic avalanche airbag outperforms in weight, ease of use and is non-hazardous travel ready.
