It is the first bio-based heat retention material used for cold-weather gear in the textile market and is made from a renewable plant-based material. The warmth retention of Sustans™ is on-par with natural down and you will immediately notice the additional loftiness and warmth of the updated style. The jacket itself is made from a 100% nylon mini-ripstop fabric with a DWR coating on both the inside and outside of shell fabric to offer a little extra water repellency when you get caught without an additional waterproof layer. We’ve also included an internal pocket that acts as a packable self-stowing pocket for the jacket. All of this combined with Grundéns traditional performance and durability has created an unbeatable combination.
