Our newest accessory, the Tracer sleeping bag liner, is incredibly soft and patterned to match our Spoon™ shape contours for extra comfort and warmth on any overnight adventure. Made of 100% recycled yarns with hollow core fibers, the THERMOLITE® EcoMade fabric is unmatched in its warmth-to-weight ratio and efficiently traps more heat to extend the temperature range of your sleeping bag. Tracer is also treated with Polygiene® Odor Control Technology, an antimicrobial finish that inhibits odor-causing bacteria. Allowing users to extend the time between laundering their sleep systems, this bluesign® approved odor-free finish protects your sleeping bag’s performance and longevity while also reducing micro-plastic shedding into the water stream.
