Our newest accessory, the Tracer Blaze sleeping bag liner, is incredibly soft and patterned to match our Ultralight Spoon™ shape contours for extra comfort and significant warmth on any overnight adventure. Tracer Blaze is made with thicker THERMOLITE® EcoMade fabric, a material woven from 100% recycled yarns with hollow core fibers. These hollow fibers efficiently trap heat to extend the temperature range of your sleeping bag without adding bulk or excess weight to your pack.

In addition to providing a physical layer that shields your bag from oils and sweat, Tracer is treated with Polygiene® Odor Control Technology, an antimicrobial finish that inhibits odor-causing bacteria. By allowing users to extend the time between laundering, this bluesign® approved odor-free finish protects a sleeping bag’s performance and longevity while also reducing micro-plastic shedding into the water stream. Though Tracer is optimized for NEMO Ultralight Spoon bags (Riff™), it can be used as a light yet warm layer inside any sleeping bag, from rectangle to mummy style.
