The Therm-a-Rest Boost 650 32F/0C sleeping bag is the ideal companion for adventurers seeking comfort, warmth and modularity.

Designed for three seasons, it is filled with RDS-certified 650 cuin hydrophobic duck down, guaranteeing lightness and optimal thermal insulation.

Its innovative design distributes the down strategically for maximum warmth, with a comfort temperature of 5°C.

This unique model offers great versatility thanks to its WarmZip system, which allows you to switch from a mummy shape, for extra warmth, to a semi-rectangular shape, for added comfort.

The double-slider closure allows you to adapt the fit to your preferences: tighter around the body or looser around the feet.

Designed for adventure, it features two zipped arm openings for reading, cooking or relaxing without leaving the bag.

Its fully recycled ripstop nylon fabric offers a soft, hard-wearing feel. The adjustable hood and anti-cold collar further enhance insulation on cooler nights.

As an added bonus, an inside pocket keeps small essentials close at hand.

Supplied with a storage net and compression bag, the Therm-a-Rest Boost 650 32F/0C is the perfect choice for those who want to combine comfort and lightness when hiking.

Warmth, lightness and freedom of movement! The Therm-a-Rest Boost 650 32F/0C adapts to your nights for tailor-made comfort in all seasons.
