AlpinLite – Wide Three-Season Sleeping Bag

The AlpinLite is a wide three-season sleeping bag designed for backpackers who want more room without sacrificing ultralight performance. It delivers the same award-winning warmth and features as the UltraLite, but with a roomier cut for added comfort.

At just 1 lb 15 oz, the AlpinLite provides premium warmth with excellent packability. It’s ideal for side sleepers, larger users, or anyone who prefers extra space while sleeping outdoors.

The bag is insulated with 850+ fill power ethically sourced goose down. This high-loft insulation offers excellent warmth-to-weight performance across spring, summer, and fall conditions.

The ExtremeLite™ shell fabric is lightweight, wind-resistant, and breathable. It protects the down from condensation and drafts while allowing moisture to escape.

The efficient mummy shape retains body heat while offering more shoulder and hip girth than standard bags. A full-length draft tube and down-filled collar help trap warmth and eliminate cold spots.

The full-length #5 YKK zipper allows easy ventilation and adjustable comfort. When conditions change, you can open the bag for airflow or zip it tight for maximum insulation.

Whether you’re hiking the Sierra, camping in alpine basins, or trekking through the Rockies, the AlpinLite delivers versatile comfort and serious backcountry performance.

Proudly made in the USA, the AlpinLite is built for lightweight missions where comfort, space, and warmth are equally essential. If you need more room and fewer compromises, this is your bag.
