Booster Add 5
The One Planet Booster is designed to add warmth to your existing sleeping bag, or can be used on its own for camping and travelling in warm conditions. This lightweight number has V-baffles filled with 750+ duck down and uses 15-denier Vapour Vent fabric, giving high warmth for weight. It makes an excellent companion when your sleeping bag is in need of a few extra degrees, or you can add another layer of clothing and take your Booster on an ultralight adventure.

For something so good, it's deceptively simple: there's not even a hood to weigh you down. It's just a tapered sack which zips open to form a luxurious comforter. (However, we’ve still included features like our famous V-baffles.)

The Booster is filled with our 750+ loft duck down, which has excellent compactability and loft recovery, with a long user life. Available in regular and large sizes.
