Grand Trunk are on to a winner with this innovative piece of kit. Rather than getting into your sleeping bag and then the hammock, the Hammock Compatible Sleeping Bagwraps around the hammock (with you in it). This avoids compressing the bag and thus losing insulation and instead creates a cosy, hanging cocoon. The slots at the end of the bag that pull together around the hammock strings can be sealed up, making it usable as a normal sleeping bag too! Rated to 0ºC and with all the usual zips and pockets, you really can keep your sleeping bag collection to a minimum.
