Ultraloft

Ultraloft is an elastic spiral and hollow fiber blend that has at least 4 to 7 channels. The main content of each fiber gives the proportion of channels. The fibers are siliconized to ensure long-lasting bulkiness.

Thanks to the large amount of spiral fibers, Ultraloft has very good elasticity. Ultraloft is mostly used for sleeping bags because it provides pleasant warmth in frosty conditions.
