Fabric Information 'Infin8T' is the new fabric of Snugpaks' flagship 'Softie' range of sleeping bags. It has a new luxuriously textured finish and incorporates the special Infin8T weave, designed specifically for Snugpak by long term fabric partners, Perseverance Mills, manufacturers of Pertex. Pertex Is the brand name for Perseverance Mills UK made, high performance, lightweight nylon. The brand leader in sleeping bag casing fabrics Pertex uses many thousands of bundles of micro fine yarn within its construction. The capillaries created between these yarns actively draw moisture away from the source and spread it across the surface area allowing it to more readily evaporate. As the moisture is evaporating from the fabric, and not from the occupant, chilling is dramatically reduced. TS1 Thermal Suede, lightweight polyester with a suede finish uses a combination of yarns with different thicknesses. Micro fine yarns (less then 1 decitex) are on the outer side, and Macrofibre yarns (3 decitex) are on the inner side, which are raised to produce a short pile, similar in feel to suede. The construction exploits a basic physical property that water will always move from a low to a high surface area, or from the Macro to the Micro filament yarns, thus moving water from the body towards the outside of the bag. Fill Information Softie or 'superfine high-thermal' is a combination of fibers with different crimp systems and surface finishes. Some are crimped, some are curled and some just left as they are. The fibers have now been updated with special binders and treatments for an excellent combination of softness and durability. Softie is extremely lightweight, and has excellent re-loft abilities, when unpacked. Black Tactical 2: Weight: 1000 grams, Pack Size: 35 x 16 cm uncompressed), Temp: Comfort: 0C Low: -5C.
