Apache StormShield™ – Ultralight 15°F Weather Proof Sleeping Bag for Alpine and Backcountry Use
Engineered for serious mountain pursuits, the Apache StormShield™ blends ultralight performance with durable and protective shell creating an award winning weather proof sleeping bag. Comfort rated to 15°F (-9°C) and weighing in at just 2 lb 2 oz (936 g), this premium mummy-style sleeping bag is designed for alpine climbers, ski mountaineers, and fast-packers pushing into cold, wet environments.
The Apache is filled with 850+ fill power ethically sourced goose down, providing exceptional warmth-to-weight performance and long-lasting loft. Its StormShield™ shell fabric is both windproof and water-resistant, making it ideal for summer mountaineering in the High Sierra, shoulder-season climbs in the Cascades, or exposed bivies on snowy ridgelines. The water resistant shell not only sheds moisture but also breathes well—crucial for managing condensation during multi-night trips in variable conditions.
The bag’s efficient cut minimizes dead air space while maintaining enough room for comfortable rest, even with extra base layers. A full-length draft tube and down-filled collar add thermal efficiency where it counts.
Whether you’re seeking a lightweight weather proof sleeping bag for glacier travel, a weather-resistant bag for sub-freezing bivouacs, or a packable option for backcountry missions where weight matters, the Apache StormShield™ delivers.
