BUERTS Down Sleeping Bag: Ultra-Light, Cold-Weather Comfort for Backpacking

For adult backpacking trips where every ounce matters, BUERTS delivers a compact, warm sleeping solution that fits cleanly in a lightweight pack. This mummy-style bag blends minimalist design with thoughtful details to support multi-season adventures without weighing you down.

Smart warmth with responsible down

Core warmth comes from 14.1 oz of 620FP, RDS-certified down. The lofted down traps heat efficiently while remaining traceable to ethical sourcing, so you can feel confident in the warmth you bring to the tent or bivy.

• Comfort temperature around 60°F for cool-to-mild nights
• Limit temperature near 44°F and extreme rating around 35°F for layered conditions
• Shell and fill designed for wind resistance and breathable warmth

Roomy, ergonomic sleep on the trail

A spacious interior—roughly 86.6 by 31.5 inches—lets you shift, roll, and settle in without feeling cramped. The ergonomic shape supports natural movement so you can rest more comfortably after a long day on the trail.

Weather-ready durability you can trust

Built with 400T 20D nylon, the bag blends a soft touch with wear-resistance. The fabric is water-repellent and designed to handle damp mornings, light rain, or chilly wind while staying breathable against your skin.

• Water-repellent and windproof for unsettled conditions
• Soft, durable fabric that remains comfortable after night exposure

Ultra-lightweight, pack-friendly design

Weighing just 1.72 lbs and compressing to about 11x6.3 inches, the BUERTS bag is built to slip into tight packs or travel smarts where space matters most.

Practical features for real-world trips

Thoughtful touches add convenience on the go. An inner pocket helps secure small valuables, and robust zippers allow you to connect this bag to another BUERTS bag for a double-wide setup when traveling with a partner or family.

• Inner pocket keeps phones, keys, or small items safe
• Zipper compatibility enables pairing two bags for extra space

Every trip, a potential fit for your plan

Whether you’re trekking alpine routes, camping at a lakeside site, or climbing to a high-altitude trailhead, this sleeping bag provides a flexible warmth-and-weight balance that can adapt to a range of cool-to-mild nights. It’s a practical option designed to support your outdoor goals without promising guarantees, just possibilities.
