2XU’s 8/10 Membrane technology has been created to create an equilibrium environment between the skin and the fabric. Our European sourced membrane delivers with waterproofness of 8,000mmH2O making the penetration through the fabric face through any conditions from a shower to a snow storm impossible. This is coupled with a moisture vapour release (M/P 10,000gm/m2/24hrs) specifically designed to avoid moisture buildup when working out. The 8/10 membrane has tiny channels which are several hundred times smaller than water vapour but several thousand times bigger than moisture vapour. Combined with a micro fleece on the inside and a hydrophilic polyester top layer, we have continued our tradition of designing fabrics from scratch specifically designed to be worn in high active sport.
