High Peak Outdoors Cascade -40 Degree Sleeping Bag | 4-Season Cold Weather Mummy

Overview

The Cascade -40 Degree Sleeping Bag from High Peak Outdoors is built for cold-weather adventures without a premium price tag. This four-season mummy bag emphasizes warmth, compact packing, and flexible setup for winter camping, alpine trips, or basecamp stays.

With a long, roomy body and a tapered silhouette, it aims to balance comfort and efficiency. The bag measures 86 inches in length and 34 inches across the shoulders, narrowing toward the feet to about 22 inches, helping reduce drafts while keeping essential space for movement.

Thoughtful details you can feel on the trail include a snug hood with a drawstring closure and a barrel lock to seal in warmth, a thermal collar to limit heat loss, and a robust #8 two-way zipper for easy entry and ventilation control. An included compression stuff sack makes packing straightforward for backpackers and car campers alike.
