Thermarest Boost 650 32F/0C

The Boost 650 32F/0C from Thermarest is a 3-season down sleeping bag. It is extremely comfortable, modular and lightweight. The RDS-certified 650 cuin hydrophobic duck down filling provides lightness and warmth. For greater efficiency, the down is distributed in key areas: close to the body, on the shoulders and on top. The comfort temperature is 5°C, and the WarmZip system allows you to gain a few degrees.

This sleeping bag has a semi-rectangular or mummy shape. It's easy to switch from one to the other, thanks to the large central zip that can be fully closed. This WarmZip does not open the sleeping bag, but rather modifies its shape. In mummy form, it will be closer to the body and warmer than in semi-rectangular form, where comfort takes precedence. The double-zip slider allows you to adjust the sleeping bag to your needs: close to the body with more room for the feet, or vice versa.

Two zippered openings let you pass your arms through. Practical for reading, playing cards or eating while keeping warm. These armholes can also be used to ventilate in hot weather.

The inner and outer fabric is the same, an entirely recycled ripstop nylon. It offers a particularly soft, pleasant feel. The Boost 650 32F/0C features a double-zipper closure on the entire left side. The hood is adjustable and there's an anti-cold collar. Inside pocket.
