Tracer Arctic

Tracer, from the brand Nemo, is a sleeping bag liner that extends the lifespan or the temperature range of your favourite sleeping bag.

Designed to perfectly match the shape of our Classic Spoon™ sleeping bag and provide optimal comfort, this sleeping bag liner is zipperless and made from Thermolite® EcoMade fabric. This fabric is woven from 100% recycled yarns and hollow fibres for superior thermal insulation and an exceptional warmth-to-weight ratio.

This sleeping bag liner also benefits from Fuze™ treatment, a permanent, chemical-free technology that uses non-ionic silver to inhibit bacterial growth and prevent odours. Your sleeping bag stays fresher for longer, allowing you to wash it less frequently and preserve its quality and performance. (Bonus: fewer washes means less microplastics released into the water.)

While the Tracer is an excellent addition to your sleeping bag, it is also lightweight and comfortable enough to be used on its own, making it a great alternative sleep system for camping and warm-weather bivouac nights.

Made from a single type of material, this Endless Promise® sleeping bag liner is fully recyclable at the end of its life: simply send it back to Nemo, and we'll take care of the rest.
