The Silk Tioga fabric is soft and breathable, while woven with ample density to help protect you from the questionable bedding in a sketchy motel room. The materials feel nice against the skin, adds a touch of warmth, and won’t latch onto other fabrics when used inside a sleeping bag or under some blankets in the loft of a winter cabin. These liners pack small enough to take along anywhere you travel, and using them in a sleeping bag will help to keep your bag lining material cleaner on extended backcountry outings. \nThe mummy and taper liners are designed for maximum efficiency, while the rectangular liner provides a bit of additional room for those who need it. \nFeatures:\n\nSoft lightweight silk\nPerfect for cold or warm weather\nBreathable and moisture-wicking fabric\nDrawcord closure (except Rectangular model)\nAttached stuff sack for easy storage \nLight and compact\n\n_______________________________________________\nSpecs\nSizing: \n\n\n\nSize\nMummy Regular\nMummy Long\nRectangular Regular\nTaper Regular\nTaper Long\n\n\nLength\n74\" | 188cm\n\n80\" | 203cm\n\n78\" | 198cm\n\n70\" | 178cm\n\n76\" | 193cm\n\n\nShoulder Girth\n\n60\" | 453cm\n\n64\" | 163cm\n64\" | 163cm\n60\" | 153cm\n64\" | 163cm\n\n\nHip Girth\n48\" | 123cm\n52\" | 132cm\n64\" | 163cm\n48\" | 123cm\n52\" | 132cm\n\n\nFoot Girth\n40\" | 92cm\n\n44\" | 112cm\n\n64\" | 163cm\n38\" | 97\n42\" | 107cm\n\n\n Stuffed Size\n\n2.25\" x 4.5\" |\n6 x 11cm\n\n\n2.25\" x 5\" |\n6 x 12cm\n\n\n2.25\" x 4.5\" |\n6 x 11cm\n\n\n2.25\" x 4\" |\n6 x 10cm\n\n\n2.25\" x 4.25\" | 6 x 10.5cm\n \n\n\n\n\n \n\nWeight:\n\n\nMummy Regular: 3.6oz | 103g\n\nMummy Long: 4.1oz | 117g\n\nRectangular Regular: 4.4oz | 124g\n\nTaper Regular: 3.3oz | 92g\n\nTaper Long: 3.5oz | 100g\n\n\nMaterials: 100% Silk\nMade in India\n_______________________________________________\nCare: Machine wash warm.
