Intended for fast-paced activities and warm weather trekking, the Diser Short Sleeve Tee from Klattermusen is constructed from an ultralight Oculus® dot mesh material that offers unparalleled breathability during intense efforts. Smooth seams on the interior and completely seam-free shoulders drastically reduce chafing and discomfort, while raglan sleeves, articulated arms and gusseted side panels allow for a full range of movement.
