Adventure Ready: Ultralight Backpacking Sleeping Bag – Alplive T400
The Alplive T400 ultralight backpacking sleeping bag brings a cozy, quilt-like feel to your outdoor adventures without weighing you down. Crafted for hikers and mountaineers who demand both warmth and packability, it features premium 650-fill power goose down inside a 20D ripstop nylon shell treated with durable water repellant. Weighing just 27 oz and compressing to an 11″ × 6.7″ stuff sack, the T400 delivers a comfort range of 32–50 °F—ideal for three-season use.

Even at full unzip, one bag easily covers two people as a duvet.

- 🛏️ Spacious Feel: Roomy footbox and wider shoulders give you freedom to shift without cold spots.
- 🔗 Double-Bag Function: Zip two Alplive T400 bags together for a cozy couple’s sleep system.

Premium Insulation & Weather Protection
At the heart of this bag is 650-fill power goose down, known for its outstanding warmth-to-weight ratio and loft. A durable water-repellent (DWR) finish on the shell fabric wards off light moisture, while the down itself is treated to resist clumping.
