Protect your bag from grime, and add one more layer to your sleep system
The NEMO Tracer™ is a 230g sleeping bag liner used inside your bag.
Its main job is to take the sweat and body oils that would otherwise go straight onto your bag, making it easier to keep the bag itself clean. Paired with a down bag that is hard to wash often, it lets you cut down how often the bag needs laundering.
Adding a single thin liner also works to top up the warmth of your sleep system. Beyond tent camping, it slots easily into mountain hut nights and travel — anywhere you want one layer between you and the bedding.
Lightweight THERMOLITE® EcoMade
The fabric is THERMOLITE® EcoMade. Hollow-core fibre made from 100% PCR polyester holds air inside the fibre, adding warmth while keeping weight down.
Weight is 230g and packed size is 16.5 × 8 × 8cm. As something you add on top of a sleeping bag it is easy to carry, and it packs down small enough to bring along on a tent night where you want a little more temperature range.
A spoon shape that lets you turn over
The pattern follows the spoon shape used in NEMO's sleeping bags.
It keeps room to move at the shoulders and knees, so rolling onto your side or turning over is less restricted. It is a shape that suits people who find narrow liners cramped.
The hardware-free construction uses no zippers or other metal parts, so nothing extra presses against you inside the bag.
FUZE® antimicrobial treatment for repeated use
The 2026 model uses FUZE® antimicrobial treatment. Based on non-ionic silver, it is intended to hold down bacterial growth and the odour that comes with it.
Through sweaty seasons and multi-night trips, it helps keep the liner usable and clean. It pairs naturally with a liner's core job of keeping the bag itself from getting dirty.
An option to use it on its own in warm weather
The Tracer™ is meant not only as a bag liner but also as a simple sleep system on its own when temperatures are high.
Summer camping, mountain huts, travel — in conditions where a normal sleeping bag would be too warm, you can sleep under this alone. Note that the Tracer™ itself has no temperature rating like a sleeping bag, so combine it with appropriate bags and insulation for the conditions.
The 2026 model drops to 230g
The fabric and antimicrobial treatment have changed from the previous Tracer™. FUZE® replaces the Polygiene® Odor Control used before, and weight goes from 261g to 230g.
The core role of protecting your sleeping bag stays the same, with packability and fabric make-up revisited in this new Tracer™.
Endless Promise® — thinking past the end of the product's life
The Tracer™ is an Endless Promise® product. Built around a single material, it is designed with recycling in mind once its service life ends.
