Hotcore Rectangular Sleeping Bag Liner

Versatile Thermal Protection and Travel Sheet for Backcountry and Camino Routes

Best For: Camino de Santiago pilgrimages, fastpacking camp setups, hostel travel, and extending the life of your synthetic or down sleeping bag.

Protect your sleeping bag from trail grime, sweat, and body oils without taking on a heavy weight penalty. Crafted from ultra-soft polyester pongee fabric, this Hotcore liner acts as a hygienic barrier whether crashing in albergues on the Camino de Santiago or fastpacking coastal routes. It washes easily after long journeys so your technical gear stays fresh season after season.

Add extra thermal warmth on chilly coastal evenings or use it standalone as a breathable sheet during humid summer nights. The roomier rectangular cut lets you stretch out naturally without feeling constricted inside your tent or hostel bed. An integrated pillow pocket secures a folded fleece or travel pillow right where you need it.

Pack it effortlessly into your backcountry haul bag or travel carry-on using the included stuff sack. Weighing just 360 grams, it is an essential, budget-friendly sheet for multi-week pilgrimages or weekend fastpacking trips along the South Shore. It stows neatly alongside your morning coffee kit for seamless, grab-and-go travel.
