Repairing tears and holes
If the fabric is damaged, avoid pulling or cutting the loose thread. Instead, use a needle to gently stitch it back into the garment. For larger tears or holes, a patch or darning is the best solution.

Before reaching the shelves, our trekking products undergo intensive testing—first in the lab, then in the field—at our R&D facility in the Mont Blanc valley.
Odour limiting tests
The Women’s Seamless Short-Sleeved Merino Wool Trekking T-Shirt – MT900 is lab-tested according to ISO 17299-3 standards. These tests validate its ability to limit odours and regulate perspiration smells, even after several days of trekking.

Wear and tear testing
To guarantee long-lasting performance, every component is subjected to accelerated lab simulations—friction, UV exposure, and more. Once the fabric passes, our field test engineers take over, putting the t-shirt through real-world trekking conditions to ensure it meets our toughest durability standards.
