Lightweight and burley define this fabric, with a triple rip-stop pattern the fabric performs well in rugged conditions. The polyurethane coating adds extra durability and weather proofing to promote the all around versatility of the fabric.



This fabric is extremely lightweight with a woven structure and the rip stop pattern promotes durability. It is made with a mono filament which improves breathability and does not absorb any moisture.



Very stretchy and durable, this mesh is designed to be constantly under load. A micro knit pattern allows the mesh to stretch and breathe simultaneously.
