Our take on the Grand Trunk 360 ThermaQuilt

The Grand Trunk 360 ThermaQuilt is a quilted hammock underquilt and top blanket in one, made to wrap around a gathered-end hammock and seal out drafts with a cinch-lock cord tunnel. It uses 20D ripstop nylon with a DWR finish and weighs 29 oz, so it packs small and suits three-season hammock camping down to about 40°F. Unlike a dedicated underquilt, it doubles as a camp blanket, but it is not a sleeping bag and adds no structure of its own. Owners like the versatility and packability; the main complaints are fiddly adjustment and warmth limits in real cold.
