FWDfit® Layer IV fabric is an 8.0 oz single sided fleece. The inner surface of this expedition weight fabric is brushed for against-the-skin comfort and the jersey outer surface provides ease of layering. This fabric is ideal for extreme weather conditions.
The shirt is constructed with set in sleeves and dropped shoulder seams to allow protection from gear and comfortable range of motion. The sturdy flat seam construction provides long lasting durability.
Our fabric’s antimicrobial protection prevents odor and prolongs the life of the fabric. Its unique wicking properties provide for quick moisture evaporation and air drying.
