Experience a warmer, fresher sleep on your next camping trip with the NEMO Liner Tracer Sleeping Bag. Constructed from lightweight THERMOLITE EcoMade fabric, this liner efficiently traps heat, moderately extending your sleeping bag's temperature range for those chillier nights in the great outdoors. The POLYGENE Odor Control antimicrobial finish actively fights against odor-causing bacteria, ensuring you wake up feeling fresh each morning. As a responsible choice, the bluesign approved finish reduces micro-plastic shedding into water streams. This liner is optimized for Classic Spoon style sleeping bags, but its versatile design fits any shape bag. Plus, its hardware-free design provides full head-to-toe comfort, making it an ideal addition to your hiking and camping gear.
