Ultra Boxer

Proper care of your Ultra Boxer Wise is essential to ensure its comfort, breathability, and prevent irritation over long distances, especially in trail running and ultra-running.

To properly wash technical sports boxers, it is recommended to follow these best practices:

Machine wash

- Use a delicate or synthetic program at 30°C
- Opt for low spin to preserve elastic fibers
- Use a liquid detergent without aggressive agents
- Absolutely avoid fabric softener, which impairs breathability and comfort

Hand wash (recommended)

- Use lukewarm water with a mild soap
- Gently clean sensitive areas (crotch, waistband)
- Rinse thoroughly without twisting the fabric

Drying

- Let the boxers air dry
- Avoid tumble dryers and any direct heat sources

To choose the right size of Ultra Boxer Wise, it is recommended to base your choice on your waist measurement to ensure optimal support without compression or chafing.

Thanks to its ultra-stretch and ergonomic materials, the Ultra Boxer naturally adapts to your body shape while ensuring long-lasting comfort for both trail running and ultra-running.

How to choose your size?

In most cases, take your usual size.

If you are between two sizes:

- Take a size up for more comfort, especially over long distances
- Take a size down for a more fitted feel (second-skin effect)

How do you know if the size is right?

A well-fitting trail boxer should:

- Stay in place without riding up
- Not create compression at the waist or crotch
- Prevent chafing over long distances
