NEMO Tracer™ Blaze Endless Promise® Sleeping Bag Liner

The NEMO Tracer Blaze Endless Promise Sleeping Bag Liner is a 356 g sleeping bag liner cut to NEMO's Spoon shape - the same wider-at-the-elbows-and-knees profile as NEMO's Spoon-shaped sleeping bags, rather than a straight mummy taper. It's hardware-free, with no zippers or snaps to fumble with in the dark or dig into you while you sleep. The fill is THERMOLITE EcoMade, a recycled synthetic insulation, treated with FUZE antimicrobial finish to control odour on multi-day trips between washes. It works two ways: on its own in warm weather as a lightweight sleep layer, or slipped inside a three-season bag to add warmth on colder nights without buying a heavier bag. At 356 g it suits hikers who want one liner that stretches across a range of temperatures rather than a dedicated warm-weather-only or winter-only piece.
