A soft, spacious liner that boosts warmth and extends your bags range without compromising comfort or packability.\nNemo says:\nOur 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.\n\nOur Verdict\nThe updated Tracer Blaze takes what was already a solid design and adds real performance gains. The switch to thicker Thermolite EcoMade fabric noticeably improves thermal efficiency, and the Spoon shape offers more room to shift positions without bunching or twisting. Yet, it manages to come in lighter than the previous version. Its warm enough to bump up your bags lower limit by a few degrees, but breathable enough that it doesnt trap clammy moisture on milder nights.\nThe Polygiene finish helps reduce odour build-up on extended trips, and the smooth interior feels comfortable against skin. Its also far easier to wash a dirty liner than a sleeping bag. At 351g (Regular), its not the lightest liner around, but the durability and packed size are spot on for multi-day use.\n- Reviewed by Ultralight Outdoor Gear\n\nFeatures\n\nHardware-free for head-to-toe comfort.\nMade with 100% recycled yarns.\nOptimized for Ultralight Spoon sleeping bags but can be layered inside any bag.\nPacks into a tidy stuff sack equipped with drawstring and webbing handle for easy carry.\nPOLYGENE antimicrobial finish extends time between laundering, increasing sleeping bag longevity and reduces\nmicro-plastics in the environment.\nPOLYGENE Odor Control antimicrobial finish is bluesign approved.\nProtected by the NEMO Lifetime Warranty.\nReduced washing saves water, energy, and detergent waste.\nTHERMOLITE EcoMade fabric with hollow core fibers offers unmatched warmth-to-weight heat retention.\n\n\nSpecifications\nRegular\n\nWeight: 351g\nPaked Size: 7.0 x 3.0 x 3.0 in / 18 x 8 x 8 cm\nFits Up To: 6′ / 183 cm\n\nLong\n\nWeight: 383g\nPaked Size: 7.0 x 3.0 x 3.0 in / 18 x 8 x 8 cm\nFits Up To: 6’6\
