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.

moisture-wicking

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.

Great purchase

Was getting chaffing previously from underwear whilst running, resulting in very sore areas.
These have eliminated the chaffing

Great purchase

They deliver what they promise

I bought the boxer shorts and used them during my marathon training block ,as well as the race. They have performed brilliantly, no chaffing or irritation at sensitive areas, as they truly are seamless on the inside. I bought the Medium and at first I thought they were tight, but they are very elastic and after a few runs I found the sizing to be just right- also, the blue color is amazing. I also bought the briefs, but I will start using them when the weather gets warm. All in all, great product, I highly recommend them.

Hey Panos,

Thanks for your lovely feedback this is greatly appreciated, We are pleased to hear that you are chafe free in your Runderwear Boxers and loved how comfortable they felt whilst training for your marathon. Thank you for your purchases with Runderwear, Happy Running!
