Product details

The Massone Light T-Shirt from Mammut is a versatile performance shirt that excels both in the climbing gym and on the rock face. It is made from a breathable blend of odor-resistant hemp, quick-drying recycled polyester, and lyocell, ensuring a comfortable wearing experience. The specially designed underarm cut allows for unrestricted movement, while the contrasting vertical back seam adds a stylish accent. Thanks to its longer cut, the shirt stays in place even when worn under a climbing harness. This T-shirt combines functionality and comfort, making it the ideal companion for all climbing enthusiasts.

  • Breathable hemp-polyester-lyocell blend
  • Quick-drying and temperature regulating
  • Underarm gusset for optimal freedom of movement
  • Longer cut for a secure fit under the harness.
