This Snugpak Softie 3 Merlin sleeping bag is a 'profiled' (unquilted) bag which uses the 'no stitch through' method of construction. Most traditionally constructed sleeping bags have quilted stitches to hold the bag and fibres in place. While developing new resins to enhance the softness of these Snugpak's bags,  a blend was developed which gave a remarkable degree of strength and structure, with self supporting fibres, allowing for the removal of all the stitch lines and cold spots that can occur with quilted bags. It also helps with re-loft as the 'Softie' filling is not held back by stitches. It is estimate that by 'profiling' Snugpak has increased the loft of their bags by up to 30%, without adding anything to the weight or packsize.

What makes Pertex products unique are their ability to manage moisture. Each square metre of Pertex used in our products is made up of around 12,000 continuous bundles of fine yarn (each bundle contains 34 strands of yarn, each strand 10 times finer then a human hair).  The gaps between these strands are very small, small enough to block water droplets but large enough to allow moisture vapour out. The small channels (capillaries) between each of the strands draw moisture away from source spreading it over a large surface area using capillary action. Any moisture forming on the skin is drawn into the weave of the lining of the product where it evaporates and continues its journey to the outside without chilling the occupant.

Reflectatherm layer - "Space Age technology in a down to earth application".

This metalised fabric is designed to reflect heat and retain warmth. A highly breathable material, which adds little to the weight or packsize of the product and provides at least 15% additional warmth whilst being undetectable by touch in the sleeping bag or garment.

Additional features include; Compression stuffsack, Layering capability, Snugfit hood, Zip baffle, Circle foot, Hanging dry tabs, Anti-snag zip two way zip.
