eVent fabric
eVent is a waterproof and breathable fabric.
Modern technogies have produced numerous fabrics that can be called waterproof and breathable, but only one came into consideration for our crux climbing shells - eVent. We started using eVent back in the late '90s (before it was even launched and while we still working for another major outdoor brand) and were immediate converts. The breathability of eVent is far superior to any other waterproof/breathable fabric, regardless of the technology used (i.e. membrane or coating). This means that comfort is maximized: perspiration build-up is significantly reduced, keeping you dry on the inside. Equally important for climbers, however, is the fact that you won't be overheating so much either, minimizing the need to constantly adjust the zip opening or take off your jacket altogether.
We use a three-layer construction that comprises the outer face fabric, the eVent membrane, and a liner - all laminated together. Whilst the membrane itself and the liner are standard for all eVent fabrics, the face fabric is worthy of attention. It is a robust nylon fabric with a weight of 105 g/m2 - making this single face layer alone heavier than many complete 3-layer laminates. It has a very smooth finish ("spuntouch") that we prefer for two reasons - durability (a smooth surface has better abrasion resistance) and the ability to hold a good DWR (durable water repellancy) coating.
