Hmlyn Hearth Rectangular Sleeping Bag

Rated for a typical UK summer campsite rather than a winter bivvy, the Hearth trades extreme warmth-to-weight for roomy comfort and a lower price point — ideal for a family trip where everyone needs a bag, not just the keenest hiker. The full-length zip opens flat to double as a duvet on warm nights, and a machine-washable liner keeps it fresh trip after trip.
