Alpha Direct Fleece Sleeping Bag Liner, by Big Agnes, is a sleeping bag liner designed to optimize your sleep whether bivouacking, in a mountain hut, or camping.
It adds a touch of warmth and comfort without ever weighing down your pack.
Its Polartec® Alpha™ Direct fabric, widely used in the outdoor industry for its exceptional warmth-to-weight ratio, delivers a soft, enveloping feel after a long day of hiking or adventure. Highly breathable and ultra-fast drying, it effectively regulates temperature while eliminating the clammy sensation often experienced with traditional sleeping bag liners.
Slipped inside a sleeping bag, it improves thermal comfort by approximately +3 °C and protects your down or synthetic fill from dirt, odors, and body oils, extending its lifespan. In a mountain hut, a hostel, or on a warm night under the stars, it can be used alone as a lightweight and comfortable layer. Its micro-fleece feel provides true comfort the moment you slip inside.
It features a minimalist drawcord hood for one-handed heat adjustment, smooth seams that prevent irritation, and a reversible construction that adapts to either side of a sleeping bag zipper. Compact and compressible, it easily fits into a small 20 × 13 × 8 cm stuff sack, making it ideal for ultralight hiking, self-supported trekking, or van life.
Versatile, lightweight, and naturally breathable, the Alpha Direct Fleece Liner significantly improves nighttime comfort without compromising mobility — an essential piece of kit for staying warm and maintaining hygiene during your nights outdoors.
