Went for my first run in these today. They were very comfortable with no chaffing. They kept my massive manhood from swinging around. Great product, 10/10, a must for any runner.

I was surprised by how well these undercrackers work. I no longer have to deal with discomfort after a run! I put off buying these for ages, wish I had just bought them sooner. You will not be disappointed, and make sure you go with the size guide on the website, as I actually went a size down from my usual size.

I’ve struggled with underwear for running for a long time so thought I’d try Runderwear a go. Initially I was sceptical but after wearing them the first time I was amazed at how comfortable they were and did exactly what it says on the tin. It feels like you’re not even wearing any. My only very small issue is that I wish I’d ordered a large and the medium is quite snug. In normal underwear I’m a medium so was expecting the same. That being said I will definitely be buying more in the future. Highly recommended.

Well worth the money - better than anything else I've tried. I'm a 32" waist, and found the small size was fine - snug, but very comfortable. Will definitely be buying more.
J
Very comfortable and kept all where it should be.
