Product details

The Massone Light T-Shirt by Mammut is a versatile functional shirt that performs well both in the climbing gym and on the rock. It is made from a breathable blend of odor-resistant hemp, quick-drying recycled polyester, and Lyocell, ensuring a comfortable wearing experience. The special cut under the arms allows for unrestricted freedom of movement, while the contrasting vertical seam on the back adds a stylish touch. Thanks to its longer cut, the shirt stays in place even 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 gussets for optimal freedom of movement
  • Longer cut for a secure fit under the harness.
