A warm 3- season sleeping bag with 7-chamber hollow-fibre filling is lightweight and space saving. Its filling and DWR fabric treatment prevent it from soaking in water and make for drying out faster.
Construction informations:
Insulating filling: 7-chamber hollow fibre. The hollow fiber has a very good insulating ability and low weight, does not absorb moisture and dries very well.
Nylon fabric: Nylon is more suitable for making a sleeping bag than polyester. It is because the fabric woven from Nylon is lighter and softer. It makes a light-weight sleeping bag and improves its loft (the filling can expand much better and take up the full volume of chambers which results in better insulation properties). DWR treatment - Durable Water Repellent – protects the filling from the drizzle, dew, and water condensing on and dripping off the inner walls of a tent. It makes for faster drying and also prolongs the life-span of the filling especially when it is goose down.
Zipper: YKK zipper has plastic protector against fabric penetration into the slider and spontaneous opening
