The Ultra Shirt is designed for demanding ultras. It combines advanced technical performance with exceptional comfort, making it ideal for long-distance outings. This t-shirt is one of the lightest on the market. Compatible with a backpack, it resists friction, even during prolonged efforts.

Cutting-Edge Technology: Everdry® FabricThe Everdry® fabric, developed in France, combines optimal technical properties: lightweight, abrasion resistance (tested to withstand backpack wear), and ultra-fast drying time. This bi-stretch fabric prevents the t-shirt from absorbing water, keeping you dry even in the most humid conditions or during prolonged ultra-trail efforts.

Anti-Irritation Seams & Superior Comfort: The Ultra Shirt features reverse thermobonded seams placed externally to eliminate any risk of irritation, especially around the collar, offering a comfort level as if you were wearing nothing. The rest of the t-shirt is assembled using Activ’Seam, one of the least intrusive stitching technologies on the market, ensuring maximum freedom of movement.

Backpack-Compatible & Durability Tested: Built to withstand extreme conditions, this t-shirt has been tested according to Martindale standards to ensure optimal resistance to abrasion caused by a backpack. While pilling may occur depending on the quality of the backpack used, it will not affect the durability or comfort of the t-shirt.

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

Albedo Capsule: Natural Cooling & Reduced ImpactAs part of the Albedo capsule, this t-shirt is made from undyed materials, reducing the emissions associated with dyeing while offering technical benefits. The ecru fabric reflects light and maintains a surface temperature up to 8°C lower than black fabric, making it ideal for running under intense sunlight. The Gold reflective strips ensure optimal visibility during night runs.
