UltraLite Down Sleeping Bag

About the Western Mountaineering UltraLite

For over 30 years Western Mountaineering has honed and perfected its design to bring you a range of sleeping bags built to meet the demands of the outdoors, from summer hikes to winter expeditions.

Forming part of the ExtremeLite Series the UltraLite delivers a lightweight, compressible down sleeping bag ideal for backpacking at higher elevations and climbing trips. With insulation powered by an ethically sourced 850+ goose down and a DWR-treated ripstop shell the UltraLite resists temperatures down to -7° C (20° F) while keeping you dry and comfortable against moisture ingress.

The tapered shape features a hooded design with a full-down collar and continuous baffle construction to lock in the loft for maximum thermal efficiency. The bag features a full-length zip and weighs in at 820g giving it a great weight-to-warmth ratio for colder nights on the trail.

The UltraLite Sleeping Bag from Western Mountaineering gives you a great piece of kit for alpine camping and trekking from the warmer months through summer and well into the cooler autumn season. Light, warm, and durable backed by Western Mountaineering’s highest-quality construction.
