Isotak® 2 brings our latest development in highly durable and lightweight waterproof fabrics combined with innovative, highly functional and robust garment design. Isotak® 2 fabric features our proprietary multi-layer composite membrane construction originally developed for Isotak® Ocean combined with a lightweight yet highly durable hightenacity nylon face. The result is an extremely lightweight and highly breathable fabrication with class leading levels of waterproof durability.

Developed to provide extreme levels of weather protection with minimal weight and bulk, Isotak® 2 provides unrivalled levels of flexibility, freedom of movement, comfort and protection. Garment features have been selected to provide the highest levels of comfort and protection with easy to use interfaces specifically designed for extreme conditions. With significant weight and bulk reductions, the Isotak® 2 range is also extremely versatile allowing sailors to use in anything from extreme offshore events through to daytime cruising.

Isotak® 2 now includes our Qulock™seam sealing system as used by our Isotak® Ocean products. The Qulock™ system includes a proprietary seam tape that is carefully tuned to the inner fabric lining to maximise waterproofness. This seam sealing is also applied under strict manufacturing processes, every Isotak® product is pressure tested, so that you can be guaranteed an extremely rugged and durable waterproof seal.

RMIT have pioneered the development of a waterproof durability testing method specifically designed to simulate accelerated wear and tear in wet conditions (when the waterproof membrane is most vulnerable). The results of their study is now published in the Textile Research Journal.

This method involves placing waterproof textiles in an accelerated wear device that simulates impact and abrasion in wet conditions. Each textile is pressure tested to determine the waterproofness after defined intervals of accelerated wear.

The chart below represents the hydrostatic resistance (Waterproofness) of each fabric after 30, 60, 90 and 120 minute accelerated wearing.

After four times (4 x) more accelerated wear testing, Zhik® Isotak® fabrics are substantially more waterproof than Musto® HPX PRO SERIES fabrics. (120 minutes as compared to 30 minutes of accelerated wear testing)
