Sea to Summit Breeze Lightweight Sleeping Bag Liner

The Sea to Summit Breeze Lightweight Sleeping Bag Liner is a 278 g mummy-shaped liner in breathable COOLMAX/Tencel fabric, built to be used either inside a sleeping bag for a hygienic, slightly warmer layer, or on its own in hot conditions where a full bag is overkill. The stretchy fit moves with you and the drawcord footbox seals off draughts around the feet. Without any insect treatment, it's a straightforward warm-weather liner rather than the bug-protection version in the same range - fine for most trips, but hikers heading somewhere mosquito-heavy may prefer the Insect Shield variant instead. At 278 g it's the lightest of the Breeze/Reactor liners covered here.
