The TERROR WEATHER STRETCH TWILL SS23 in Sage.
Welter Shelter's Parka style which has become infamous for its absolutely good fit and minimalistic look: a classic, minimalistic exterior with full functionality underneath. The exterior is made of a waterproof high performance fabric. A wide choice of high performance fabrics like this nina spina fabric. This Nina Spina fabric is a type of serge structured fabric. Serge means the weaving in itself is already so tight it already gives water repellent and windproof properties. It's a durable and firm fabric often used for military purposes and suiting. Typically you see a diagonal rib weave from left to right going up. This fabric was enhanced by bonding and laminating the backside for absolute waterproofness and breathability. The outer serge fabric is on top of this treated with a DWR coating for extra water-reppellency. Basically, Welter Shelter created an almost indestructable cloth that will last for years.
