Sophie Morris said: Incredibly comfortable

Pure comfort when exercising! You really do forget they're there and it's such a relief to know they don't budge or move at all while I'm running! I'm tempted to wear them all day every day. I love them. Will definitely purchase again and highly recommend!! Thank you runderwear team :)

Laura Dumbelton said: Second pair purchased

I use the briefs for both running and hiking. This is my second pair purchased as they are so comfortable, secure and supportive. They don't ride up and i don't notice I am wearing them. Easy to wash and dry quickly. Delivery came swiftly. Definitely recommend.

Soft material, really comfortable.

Lydia said: Comfort and performance.

I first bought these as an impulse purchase at a marathon expo, and can't praise them enough! The material is very soft, and the wicking properties are excellent - I particularly like the no-seam feature, which makes them slightly more discreet, and enhances overall comfort. While I appreciate the thicker waistband, they do tend to wear a little high for my liking, but this is only really an issue if I have a low-rise legging, or wear them under jeans - which I do on any occasion where I want to stay 'fresher for longer'!
