Therm-a-Rest Boost 650 32F Sleeping Bag | Ultra-Comfy, Customizable Warmth for Three-Season Adventures
The Therm-a-Rest Boost 650 32F Sleeping Bag is built for backpackers and campers who want maximum comfort and adaptability. Featuring 650-fill RDS-certified hydrophobic down with Zoned Insulation, this bag delivers plush warmth exactly where you need it. Its innovative WarmZip™ Technology allows you to customize the bag’s shape and internal space, switching between a roomy semi-rectangular fit and a heat-efficient mummy-style design with just a zip—boosting warmth by up to 10°F (6°C).
Designed for versatility, this sleeping bag includes multi-use arm holes for enhanced livability, letting you adjust the WarmZip, read a book, or play cards without leaving your cozy cocoon. The YKK anti-snag zippers, cinchable hood, puffed draft collar, and zipper draft tube all work together to seal in warmth on chilly nights. Built with sustainability in mind, the GRS-certified 100% recycled nylon shell and liner are PFAS-free, offering an eco-friendly solution without compromising durability.
