Mammut Massone PatchT-Shirt

What Our Gearhead® Experts Are Saying:"This tee is surprisingly functional for something so simple. The extra length really does help it stay put under a harness, and the organic cotton feels stronger than most climbing tees I’ve worn. It’s the kind of shirt I end up using for both gym days and everyday wear."Long days at the crag feel a little more dialed in with the Massone T-Shirt Patch. Mammut builds it entirely from soft, organic cotton, giving us breathable comfort that still holds up to abrasive rock and shifting movement on vertical terrain. The slightly extended cut keeps the tee tucked beneath a harness as we reach, stem, and high-step through problem areas.Between burns, the simple patch logo and clean silhouette transition easily from climbing to everyday wear. Lightweight and easy to layer, it’s the kind of tee we can pack for a weekend trip or pull on for a quick gym session—always soft, always ready to move.
