Men's Shirt 355 - Black

The Shirt 355 Wise, designed like true ultra-runner gear, requires special care to maintain its breathability, thermoregulation, and durability.

To properly wash a technical trail T-shirt, we recommend following these best practices:

Machine wash

- Use a delicate or synthetic cycle at 30°C
; use a low spin cycle to protect
the technical fibers; use a liquid detergent without harsh chemicals
; avoid fabric softener, as this impairs
breathability and moisture management Hand wash (recommended)
: Use lukewarm water and a mild detergent
; gently
clean the areas exposed to sweat; rinse the garment thoroughly without wringing it out

Drying

Let the shirt air dry
. Avoid the dryer to preserve the technical properties of the fabric

See the size chart on the product page.

The choice between these two models depends mainly on your running conditions and your need for versatility. While the T-Shirt 350 offers the simplicity and classic comfort of a high-performance trail top, the Shirt 355 is all about modularity, allowing you to adapt to changing weather and terrain conditions.

The Trail Shirt features unique functions. It allows you to easily roll up and secure the sleeves as needed, depending on the temperature, as well as open special ventilation openings on the back to optimize airflow during intense exertion. Additionally, the collar can be raised to provide welcome protection from cold wind or the sun.

Finally, the shirt features two discreet and practical pockets, ideal for keeping small items or snacks within easy reach. It’s the perfect choice for trail runners looking for a technical, highly adaptable, and functional garment for long runs.

Yes, absolutely. The 355 shirt was specifically designed to accompany you on ultra and multi-day hikes, and its design works perfectly with a trail backpack.

It features two front pockets that are ideally positioned at chest height. When you’re wearing your trail backpack, the pressure from the shoulder straps presses against the fabric, helping to secure your phone even better and keep it from shifting while you’re running. These pockets are also perfect for stashing sponges to cool off on the go.

Finally, the flip-open vents on the back are designed to remain accessible and functional even while the backpack is being worn. This allows you to adjust ventilation and regulate your body temperature without being hindered by your gear.

Yes, the shirt features reinforced shoulder panels—an area that’s particularly prone to wear and tear during outdoor activities—which provide effective protection from the sun’s rays.

These reinforcements also improve the garment’s overall structure. They ensure a high level of comfort at the points of contact and while wearing the shirt, especially when hiking with your trail backpack.
