A lightweight, packable liner that balances comfort, warmth and sustainability for all-season versatility.\nNemo says:\nOur newest accessory, the Tracer sleeping bag liner, is incredibly soft and patterned to match our Classic Spoon shape contours for extra comfort and light warmth on any overnight adventure. The physical layer helps shield your bag from oils and sweat, and Tracer is also 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.\nTracer is made with lightweight THERMOLITE EcoMade fabric, a material woven from 100% recycled yarns with hollow core fibers. These hollow fibers efficiently trap heat to moderately extend the temperature range of your sleeping bag without adding bulk or excess weight to your pack. Though Tracer is optimized for NEMO Classic Spoon bags (Disco, Forte), it can be used as a layer inside any sleeping bag, from rectangle to mummy style.\n\nOur Verdict\nThe updated Tracer blends thoughtful design with functional updates. The use of recycled Thermolite EcoMade fabric provides a soft feel with decent thermal performance, helping to raise the lower limit of your bag while remaining breathable on warmer nights. At 258g (Regular), it packs down small but adds meaningful comfort.\nThe Spoon shape provides extra space around the knees and elbows, making it less restrictive than most liners. The structured footbox is a welcome addition. Treated with an antimicrobial finish, it stays fresher for longer. It also means your sleeping bag stays cleaner, which is especially useful with down bags. \n- Reviewed by Ultralight Outdoor Gear\n\nFeatures\n\nHardware-free for head-to-toe comfort.\nMade with 100% recycled yarns.\nOptimized for Classic 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: 258g\nPaked Size: 6.5 x 3.0 x 3.0 in / 16.5 x 8 x 8 cm\nFits Up To: 6′ / 183 cm\n\nLong\n\nWeight: 279g\nPaked Size: 6.5 x 3.0 x 3.0 in / 16.5 x 8 x 8 cm\nFits Up To: 6’6\
