Product Details

The Sea to Summit Breeze Lightweight Sleeping Bag Liner is built for warm nights when moisture management and airflow matter more than added insulation. The breathable blend of COOLMAX® EcoMade and biobased Tencel Lyocell fibers wicks moisture to help keep you cool and comfortable, whether you’re using it inside a sleeping bag or sleeping in it on its own.

In real use, what stands out is how easy it is to live with. The stretchy knit fabric moves well if you tend to roll around, and the mummy version adds arm openings and a drawcord footbox for better ventilation and freedom of movement. It dries quickly, washes easily, and HeiQ Fresh odor control helps it stay fresher on longer trips. Just as important, it helps cut down on how often you need to wash your sleeping bag, which is a practical way to preserve loft and extend its lifespan over time.
