The Sea to Summit Breeze Mummy Sleeping Bag Liner keeps the bugs out and the comfort in
What Our Gearhead® Experts Are Saying:
"The Sea to Summit Breeze Mummy Sleeping Bag Liner has become a permanent part of my kit for both backcountry trips and travel. The Insect Shield treatment gave me real peace of mind on a trip through a notoriously buggy river valley, and the Coolmax and Lyocell blend kept things genuinely comfortable on warm nights when I was using it as a standalone layer rather than inside a bag."
A sleeping bag liner earns its place in the kit by solving multiple problems at once, and the Sea to Summit Breeze Mummy Sleeping Bag Liner does exactly that. The stretch-knit blend of 70% Coolmax EcoMade polyester and 30% biobased Tencel Lyocell wicks moisture efficiently in humid conditions to prevent that clammy, restless feeling that turns a warm night into a long one, while the stretch construction moves naturally with the body rather than fighting every shift and turn through the night.
Insect Shield treatment repels certain bugs directly through the fabric, adding a layer of protection in environments where the alternative is lying awake listening to the situation worsen. The mummy shape with a drawcord base keeps the liner in place inside a sleeping bag or works as a standalone layer on warmer nights, and the whole thing compresses into a storage case measuring just 5.9 x 2.8 x 4.3 inches at 10 ounces. Whether the bed is a tent, a hut, or a hostel bunk, this liner delivers a clean, comfortable, and protected sleep environment wherever the trip takes you.
