Technology:
STORMFLEECE™ PRO fabric uses patented technology by Singtex® to create a single-layer fabric (without a membrane), made from nearly 70% recycled materials, that is capable of resisting wind and rain while offering excellent thermal insulation, high breathability, durability, and a very soft feel. The fabric has been created using a combination of techniques, and its innovative construction provides a fabric that leverages the strength and flexibility of fibers, while significantly reducing material consumption. Its densely woven structure minimizes fiber and yarn waste, resulting in a unique fabric with a durable exterior and a soft interior feel.
The OS2O FAST&LIGHT collection powered by STORMFLEECE™ PRO allows the development of lightweight, durable, and technical single-layer products. Fabric developed under the BLUESIGN® System Partner.
