Featured Review

Changed my life

"After a particularly bad week involving chafing in unspeakable areas, I googled solutions whilst limping back home. This was the first result and never has money been so well spent! They arrived quickly, fitted as described, and immediately the chafing was a thing of the past. I’m really impressed with how comfortable they are" - Iain B

seamless

Sometimes less is more – and for runderwear, less seams = more comfort. No side seams, no labels and most importantly, no rubbing. There’s less wastage, too – so choose seamless to run smooth and free.

breathable

The little things often make the biggest difference… Micro-perforations allow our underwear to breathe all year-round and improve airflow – which means you won’t overheat. Be cool, stay comfortable.

Comfy, stretchy, long

Great boxer shorts for all activities. Bought these for running and found them very comfortable. The rubber strip at the bottom of the leg keeps them in place so they don't ride up. They are just long enough as well.
Very happy with my purchase.

Ladies! look in the men's section!

I found that my current underwear was causing chaffing when I started my training for my first marathon so my partner decided to buy me some ladies briefs - although MUCH better, I did find they caused a small amount of chaffing on runs when it was raining after a few washes (maybe I gained weight or they shrunk in the wash and no longer fit as well? who knows). the chaffing occurred right on the inside of the thigh where the pants made contact with the skin, so, I decided to try some runderwear pants that were a little longer.

Now on the women's side, the boxers appeared to be quite short in length (an issue I have had previously with women's boxers or riding up and curling of material on the inner thigh and didn't want to risk it). The next length up are quite a bit longer, reaching just above the knees (great for loose running shorts as an underlayer but alas mine had a liner and likely cause me to be too warm on hot days and create a weird double lining look).

So. I had a look on the men's side. LO and BEHOLD! The men's boxers were the PERFECT length. Without hesitation, I decided to buy myself a pair opting for a medium. I will never look back. they don't ride up, there is no rolling of the fabric on the inner thigh and don't stick out the bottom of my shorts lining. Screw societal norms. These are the best pair of running pants I have ever tried.
