Whether on trekking tours and in tents as an extra layer of warmth or as a hygienic layer in hostels: The Breeze Liner Mummy Liner from Sea to Summit ensures dry, fresh sleeping comfort. The stretchy and incredibly soft Coolmax EcoMade knit material made from synthetic fibers and TENCEL offers maximum freedom of movement and efficiently wicks away moisture. This means you can enjoy a dry sleeping experience even in high humidity, and thanks to HeiQ-Fresh technology, the liner remains odor-free even after extended use. The foot box with drawstring can be opened or closed as needed; the upper entry is comfortably accessible with snap buttons. This also creates two armholes, allowing you to sit in the tent while "wearing" the liner and enjoy your morning muesli with an extra layer of warmth. For gram counters, this liner might be a bit too large and heavy, but for those who want to indulge in extra comfort while traveling and backpacking, the Breeze Liner Mummy Liner is an essential accessory.
