Nemo - Tracer Endless Promise Sleeping Bag Liner

from $69.95

Overview

If you’re looking to extend the life or temperature range of your favorite sleeping bag, Tracer™ has you covered. Patterned to match our 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.

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, this gear can be sent back to NEMO for recycling through our take-back program at the end of its usable life.

Key Benefits

  • Adds versatile comfort and modest warmth while keeping your sleeping bag cleaner, fresher, and longer‑lasting.

  • Designed to reduce washing frequency, helping maintain your bag’s loft and overall performance over time.

  • Shaped specifically to fit Classic Spoon® sleeping bags, it adds warmth, cleanliness, and comfort without excess bulk.

  • An Endless Promise® product, this gear is carefully engineered for recyclability, designed with easily removable hardware, and accepted by strategic recycling partners.
