Therm-a-Rest Boost 650 20F/-6C Regular Wide (183 cm) Sleeping Bag - Morning Blue

The Therm-a-Rest Boost 650 sleeping bag is a high-performance mummy bag designed for backpackers who demand warmth without excess weight. Featuring 650 fill Nikwax Hydrophobic Down, this bag offers excellent insulation even in damp conditions. The regular wide cut provides extra comfort for side sleepers, while the box baffled construction eliminates cold spots. With a temperature rating of 20°F (-6°C) limit and 32°F (0°C) comfort, it's ideal for three-season adventures.

Advantages

Nikwax Hydrophobic Down treatment repels moisture and dries faster than untreated down. SynergyLink Connectors integrate the bag with your sleeping pad for stability. Zoned Insulation places more fill where you need it most, and the Toe-asis Foot Warmer provides extra space for your feet.
