The Snap Zip T-Shirt is a technical, high-performance trail baselayer. It utilises a zoned combination of Apex-Lite fabric, which is a super lightweight grid structure fabric that dries extremely quickly, together with super wicking bi-construction Apex-Pro fabric across the back and under the arms for extremely effective moisture management. Both fabrics are treated with POLYGIENE® permanent odour control, so the Snap series really can become your second skin
