Comfortable even on longer rides

It worked

I went around Lake Balaton in it. It was comfortable throughout. The price-value ratio is also suitable for me.

The size doesn't fit me well at all, a little wide in the waist so that it fits my leg well. After a few hours the sweat accumulates a little and rubs against my private parts.

Cycling undershorts

Good, comfortable undershorts

icon-circle-checkmark verified purchase

Under-shorts used for my first 10-day cycling trip to Austria, on an electric bike with a very comfortable saddle. I didn't sweat much. These undershorts are not really comfortable, but without it I would have had more pain in the crotch, so I'm satisfied but nothing more.


Comfortable and very convenient

Undershorts support

We wanted to provide the support you need, even without straps. That's why these close-fitting undershorts have a wide elasticated waistband that adapts to you and stays in place, without requiring any adjustments.

A second skin with comfort to boot.

This pad is designed for regular users.The support foam is soft with medium firmness. Provides good user comfort and protects the cyclist's pressure zones for rides of up to 3 hours. Foam thickness: 13 mmFoam density: 100 KG/m3Foam firmness: 25 KPa

Shorts, undershorts

Undershorts are to MTB what kilts are to Scotland: you wear them against your skin!To avoid chafing, we therefore recommend changing them and washing them as if they were underwear.And when you're riding, your shorts and undershorts should never be attached.Why? Because each has their own role to play:- The undershorts stay in place for comfort and support.- The shorts move with you for better freedom as you cycle
