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 bag), and ultra-fast drying time. This bi-stretch complex allows the t-shirt to never become waterlogged, keeping you dry even in the wettest conditions or during prolonged ultra trail efforts.

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 in Activ'Seam, one of the least intrusive sewing technologies on the market, ensuring maximum freedom of movement.

Backpack friendly and durability tested: Built to withstand the most demanding conditions, this shirt has been tested to Martindale standards to ensure optimum resistance to abrasion from 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 shirt.

UPF40 Sun Protection: Although this t-shirt is not certified as sun protective clothing, it has been tested with UPF40 protection, allowing you to enjoy long hours outdoors while staying protected from UV rays.

Albedo Capsule: Natural cooling and reduced impactAs part of the Albedo capsule, this t-shirt uses undyed materials, reducing dye-related emissions while offering technical benefits. The ecru fabric reflects light and maintains a surface temperature up to 8°C lower than a black fabric, ideal for running in bright sunlight. The Gold reflective stripes ensure optimal visibility during your night runs.

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.

On this new version we have put Everdry Air material on the entire T-shirt.
