The Ultra Shirt is designed for demanding ultra runners. It combines advanced technical performance with exceptional comfort, ideal for your long-distance outings. This t-shirt is one of the lightest on the market. Backpack-compatible, it resists chafing, even during prolonged effort.
Cutting-Edge Technology: Everdry® ComplexEverdry® fabric, developed in France, combines optimal technical properties: lightness, abrasion resistance (tested to withstand the wear and tear of a pack), and ultra-fast drying time. This bi-stretch complex ensures the t-shirt never becomes waterlogged, keeping you dry even in the wettest conditions or during prolonged ultra trail runs.
Anti-irritation seams and superior comfort: The Ultra Shirt features reverse-bonded seams, positioned on the outside to eliminate any risk of irritation, especially at the collar, providing a comfortable feeling as if you were wearing nothing. The rest of the t-shirt is assembled with Activ'Seam, one of the least intrusive sewing technologies on the market, ensuring maximum freedom of movement.
Backpack-friendly and durability tested: Designed to withstand the most demanding conditions, this t-shirt has been tested to Martindale standards to ensure optimal resistance to abrasion caused by a backpack. While some pilling may occur depending on the quality of the bag used, it will not affect the durability or comfort of the t-shirt.
Albedo Capsule: Natural Cooling and Reduced ImpactAs part of the Albedo Capsule, this t-shirt uses undyed materials, reducing dye-related emissions while still offering technical benefits. The ecru fabric reflects light and maintains a surface temperature up to 8°C cooler than black fabric, ideal for running in intense sunlight. Gold reflective stripes ensure optimal visibility during your night runs.
Composition: 76% Polyamide, 24% Elastane
This product has a lower environmental impact due to local and responsible production. Made from Everdry® materials developed by our French partner Payen, it is then assembled in Portugal at Petratex, in a factory operating 100% with renewable energy. With only 1,490 km between each manufacturing stage, this production chain considerably reduces the carbon footprint of the product, almost 30 times less than a t-shirt made in Asia.
We offer free shipping on orders over CHF 100.
