So comfy!!!

Where have these knickers been all my life????!! I've suffered for years with uncomfortable, irritating knickers whilst running and in the gym. I was going to try an expensive pair of special running knickers but I decided to give these a shot first - I'm so glad I did! I went out for a long run in these and it's honestly the first time I've never thought about my knickers while running! No rubbing, no chafing, no riding up , no getting soaking wet - it's like they're not even there! So glad I didn't spend £30. I've just ordered two more pairs!

These are awesome

I have got lots of these now, they are so light and comfortable that l wear them as my daily pants. Highly recommended

Great value

Excellent value for money. Comfortable to wear & don’t ride up. I’m size 8-10 & size M-L fit perfectly.

Wicking knickers!

Don’t hold sweat during exercise so very comfortable to wear.

Additional Product Information


Main fabric

  • 93% Polyamide
  • 7% Spandex

What makes the running briefs so breathable?

The knit structure of these sports briefs is tailored to the areas where you perspire the most (lower back in particular): maximum ventilation for even more comfort. The very fine fabric dries very quickly.

What is the shape of these running briefs?

We developed these sports briefs with a "hybrid" shape combining briefs (at the front) and hot pants (at the back) for greater freedom of movement around the groin and greater coverage and sculpting for the rear.



Product testing

PERSPIRATION WICKING: The perspiration wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it. WASHING: The washing and drying tests guarantee good stability (dimensional stability and colorfastness) These tests are regularly conducted by an independent laboratory to confirm that our quality standards are applied.
