Mammut Close The Loop T-Shirt Men 2.0

Mammut Close The Loop T-Shirt Men 2.0 in Phantom Black

A sustainable T-shirt we’ve made entirely from reprocessed waste.

The Close The Loop functional T-shirt is 100% ECONYL® regenerated nylon. Some of the material comes from old climbing ropes collected by Mammut at select climbing gyms and stores.

The Close The Loop T-shirt is lightweight, functional and perfect for outdoor activities all year round. It dries in no time and has a 3D material structure that makes it extra comfortable on your skin. Offset seams prevent uncomfortable pressure when carrying a backpack. 

To reduce unpleasant odors, the T-shirt is treated with HeiQ Pure technology developed in Switzerland. This helps conserve resources since less washing is required. And because it’s made of 100% regenerated nylon, the material can be reused over and over again – closing the loop.
