What Our Gearhead® Experts Are Saying:"This drawcord-base liner is my choice for warm, sticky nights on the trail. The stretch-knit fabric feels soft, moves with me, and wicks moisture fast so I never wake up clammy. It fits easily inside any sleeping bag and adds comfort without extra bulk."We bring the Sea to Summit Breeze Liner with Drawcord when humid weather threatens our sleep system. Its blend of COOLMAX EcoMade and TENCEL lyocell manages moisture exceptionally well, keeping us dry and comfortable when temperatures rise and the air feels heavy. The stretch-knit construction offers impressive freedom of movement, adapting to our sleeping position and the interior shape of any sleeping bag. Designed for outdoor users who want breathable comfort without added weight, the mummy-style liner cinches neatly at the base to retain warmth on cooler nights while remaining airy enough for warm conditions. Lightweight, compact, and hygienic, it creates a soft and refreshing barrier wherever we settle in for the night.
