Tracer Arctic Sleeping Bag Liner

If you’re looking to extend the life or temperature range of your favorite sleeping bag, Tracer has you covered. Patterned to match the Classic Spoon shape contours for a comfortable, efficient fit, this sleeping bag liner is hardware-free and made with THERMOLITE EcoMade fabric. EcoMade is woven from 100% recycled yarns with hollow core fibers to better trap heat and offer an unmatched warmth-to-weight ratio.

Tracer is also treated with FUZE, a permanent, chemical-free technology that uses non-ionic silver to inhibit bacteria growth and prevent odors. This helps keep your sleeping bag cleaner longer, so you can extend the time between laundering and ultimately maintain your bag’s quality and performance. (Bonus: Less washing reduces micro-plastic shedding into the water stream.)

While Tracer works great as an addition to your bag, it’s also lightweight and comfortable on its own, making it a great alternative sleep system for warm weather camping and overnights.

An Endless Promise product manufactured from a single type of material, this sleeping bag liner is fully recyclable at the end of its life — just send it back to NEMO, and we’ll handle the rest.
