Vent X®
Vent-X is a coated waterproof breathable 2-Layer fabric. It has an industrial strength, oxford weave nylon 66 face fabric, with a 4-pass hydrophilic coating on the back. A 4-pass coating means 4 separate coatings are built up on the back of the fabric before they are all heat cured together.
Defined as a breathable monolithic coating by the industry, water vapour on the inside surface of the coating is transported to the outside surface of the fabric via a series of molecular chains.
When applied under strict quality standards, coatings are more durable than glued laminates, and more importantly they are not so susceptible to contamination as the new generation, 3-layer laminates.
In terms of waterproofness the coating can withstand a 20,000mm waterhead pressure. This figure is retained even after continuous washing and wear.
We have been using this fabric for over 35 years and the reasons for doing remain unchanged today. It has a perfect durability versus lightness ratio for the challenges of New Zealand’s rugged outdoor environment. It is an ideal fabric for durable waterproof/breathable overtrou and jackets.
The outer surface of the fabric is treated with the best fluoropolymer water repellent specification we can obtain. This treatment prevents surface wetting which is critical for maximum breathability.
Vent-X is ideal for anything from sub-alpine bush bashing and bum sliding on firm snow to everyday work wear.

Susan –
These pants have handled everything from Westland storms to horizontal Patagonian rain and soaking PNW downpours, keeping me completely dry underneath. They’re tough, reliable, and breathe surprisingly well for heavy duty rain gear. The full-length zips make it easy to pull them on and off over crampons and boots. A solid piece of kit I can always count on
Lori Parker –
Awesome pants – have been wearing them for tramping for the past 10 years; and now using them on a farm in Tasmania to keep dry. I highly recommend these pants! Thank you for creating such high quality products.
