Just not very good

Too tight and too loose in all the wrong places (and that's having sized-up):
- waistband rolls down, bunching together and making them very uncomfortable to wear over longer periods of time
- also a tad too tight around the thighs
- and too loose in the mid-section
...finally, not really very sweat-wicking either...

Was a trial-buy as wanted to see what they were all about, but would highly recommend to look elsewhere. Especially disappointed with the waistband, which is a clear design error (and has been mentioned in other reviews too)

great present

I bought these for a friend who is running a lot and has always struggled with chafing. He was really pleased with them - said they didnt ride up, very breathable and comfy!

Mens boxers - OK!

Following years of using under armour compression shorts I thought I’d try these after suffering some undercarriage chaffing on a 100miler. Over all the boxers are comfortable and feel great. They do have a sticky rubber on the front of each leg but I still found mine riding up (to be very short)!

I was also expecting these to be seamless but the undercarriage section still has quite pronounced seams. These have not causes any issues yet but I could see them doing so on a long, hot or wet run!

After only a few wears the material has started to bobble as well. Not an issue but not what I’d expect from a premium pair of running boxers.

Overall they seem to do the job but IMO not worth the extra money compared to other Lycra shorts.

Boxer shorts

Worn x3 times now and can’t fault them , feel comfortable and no chafing… great buy

Absolutely awful

The waist band on these things rolls like crazy. The shorts barely breathe.
