Thanks to the SoftLite finish, this fabric is very pleasant to the touch, almost to give the impression of cotton. In contrast, it dries much better, lasts longer and is much lighter.

Thermicfibre 4, the successor to Hollowfibre 4 are spiral twisted polyester fibers that have 4 channels. The air retained in these ducts causes their excellent insulating properties. Thanks to the elastic binding and the specific placement in the layers, the fibers achieve the LOFT. This means that after unpacking from the package they take up the original volume and fill the space of the sleeping bag chambers. Maximum effect and durability is achieved by applying a layer of silicone to the fiber surface, which fixes the relative position of the fibers and reduces mutual friction. Hollow fibers perfectly insulate even at high atmospheric humidity, are non-absorbent, dry quickly, are non-allergic. They are easy to maintain, can be washed and dried in a classic way.

Thanks to the DWR treatment, the fabric is highly water-repellent, so the water drops tend to run down, so it can withstand shorter drizzle or morning dew.
