2026 New Nemo Tracer™ Blaze Endless Promise® Sleeping Bag Liner/Liner (Warmer Version)

If you're looking to extend the life of your beloved sleeping bag or extend its temperature rating range, the Tracer™ Blaze liner is the perfect choice. Its ergonomic cut perfectly conforms to the shape and contours of our Ultralight Spoon™ sleeping bag, providing a comfortable and efficient wearing experience. This liner contains no stiff hardware and is made from THERMOLITE® EcoMade fabric. EcoMade fabric is woven from 100% recycled yarn, and its unique hollow fibers more effectively lock in heat, providing an unparalleled warmth-to-weight ratio.

The Tracer Blaze also features FUZE™ technology. This is a permanent, chemical-free technology that uses non-ionic silver to inhibit bacterial growth and prevent odors. This helps keep your sleeping bag clean for longer, extending washing intervals and ultimately maintaining its quality and performance. (Additional benefit: Reduced washing frequency helps reduce microplastic ingress into water.)

While the Tracer Blaze excels as a complementary accessory to a sleeping bag, it is also lightweight and comfortable enough to be used as a standalone lightweight sleep system when camping or spending the night in warm weather.

As an Endless Promise® product, this sleeping bag lining is made from a single material and is fully recyclable at the end of its lifespan—simply send it back to NEMO and we'll take care of the rest.
