Pertex Equilibrium is the result of the extensive development work in the laboratory and field. Pertex Equilibrium applies capillary action technology conventionally applied to base layer products. This means that during high aerobic activity, moisture is transported away from the skin to the outside of the fabric where it evaporates, hence creating body temperature Equilibrium.
Pertex Equilibrium has a unique denier gradient structure. It combines two different yarns with different properties. On the inside you'll find a yarn with larger filaments, on the outside a yarn with smaller filaments. You can actually see the different yarns when comparing the inside and outside of the fabric. Following the laws of capillary action, moisture will move from larger filaments to smaller filaments.
Pertex Equilibrium 3-dimensionally wicks the moisture away from the body. The engine behind this process is your own body heat. On the outside the smaller filaments have a relatively high surface area which causes the excessive moisture to evaporate quickly. Through evaporative heat loss Equilibrium reduces overheating, which in return reduces excessive sweating. This process creates body temperature Equilibrium.
