eVent is associated with waterproof textile technology used in products such as shells, footwear, tents and gloves. Sewport discusses its expanded-PTFE construction and Direct Venting approach, explaining the role of the membrane in moving moisture vapour while resisting liquid water. That role differs from the visible exterior textile.

Separate eVent's Membrane Role From the Garment's Other Materials

Use the specification for the particular product when identifying its materials. The technology name alone cannot establish the outer yarn, lining or weight of a finished garment. Reading those layers separately helps explain why products using eVent can have different surfaces, constructions and recommended care.
