Best Use: Packable and Durable Building on the success of the StrongFleece line-up, the new StrongFleece 190 Zip-T features an improved fit for layering and high-output activities. This highly versatile mid- to outer-layer fleece offers extreme breathability and durability not typically found in traditional fleece styles. Hunters can wear this layer in various conditions, from light rain to busting through the brush, without sacrificing breathability. The high durability and water resistance lends itself well to a wide range of terrains and weather conditions.
