Thanks to the polyester jersey Trevira Bioactive fabric, this T-shirt stands up to heavy wear with high resistance against abrasion and pilling. The fabric balances durability with breathability so you don't have to sacrifice comfort for protection. The fabric construction also makes this T-shirt great either as a base or second layer. This T-shirt comes with a central front zip and a zipped chest pocket for extra storage. Finished with reflective elements to keep you visible while working on the ground or during helicopter rescues, the unisex High Zip 2 T-shirt combines comfort and function for mountain rescue professionals.
