What Our Gearhead® Experts Are Saying: "I love this liner for warm-weather trips and hostel travel because it feels incredibly soft and keeps me dry through the night. The pillow sleeve is a game changer—it keeps everything in place so I’m not chasing my pillow around. It packs small, washes easily, and makes my sleep setup feel instantly upgraded." We turn to the Sea to Summit Breeze Lightweight Liner when we want a fresh, comfortable sleep environment without adding bulk to our pack. The blend of COOLMAX EcoMade and bio-based TENCEL lyocell creates a moisture-managing, silky-smooth fabric that keeps us dry and comfortable from the first trailhead nap to multi-night backpacking trips. Its rectangular cut gives us room to move, and the integrated pillow sleeve anchors our headrest in place for consistent comfort. Odor-resistant HeiQ Fresh technology helps the liner stay pleasant through extended use, making it a reliable companion for everything from warm-climate backpacking to global travel. Whether used inside a sleeping bag or on its own in hot conditions, the Breeze liner elevates our rest with breathable softness and packable convenience.
