Chafe-free comfort
"Fantastic product and the most comfortable running underwear I’ve ever worn!! The guys at Runderwear have got it spot on and it’s great to know that I can run for mile after mile in total comfort. Great service and super-fast delivery!"

Ergonomic Fit
Specifically engineered for runners, by runners to deliver the ultimate experience in comfort. Durable fabric with 4-way stretch movement allows you to run freely and provides support to your body, making it the perfect first layer against your skin.
Chafe-Free
Our multi award-winning underwear range was created as a solution to the bane of many runners’ lives – chafing. Each different product is designed with the same core elements in mind, then tweaked to suit different style preferences and provide an anti-chafing solution for all.
Seamless Design
The underwear is created on a 360° seamless machine from a single piece of fabric, which means no side seams or labels. This significantly reduces the risk of skin irritation and minimises wastage during the production process versus the traditional cut and sew method
The Runderwear™ Men's Running Briefs are designed to provide exceptional fit, feel and support during your run. Our award-winning underwear will keep you chafe-free - guaranteed. Constructed using 360° seamless technology, which means there are no side seams or tags, resulting in less irritation against your skin. Carefully positioned micro-perforations make the fabric breathable, optimising airflow and core temperature control. Lightweight, technical fabric is moisture-wicking and removes sweat quickly from your skin to keep you dry

The best running/exercise underwear available! I’ve worn both the boxers and the briefs. Both are amazing, but the briefs especially during warm summer months of training and racing.

I'm a seasoned runner who hadn't sampled the benefits of support. I was in pain after an operation and after struggling for 2 weeks, I ordered some running briefs which gave me instant relief. I will be using these for recovery and eventually running again. Thankyou.

Very happy with my purchase, very comfortable. Just wish they were not MADE IN CHINA

Super impressed with Runderwear, was recommended by a friend to try. The briefs are lightweight, comfy and somehow keep the sweat away! This was the first product I purchased, have now gone on to buy the shorts which are ultra lightweight and impressive!
Thank you for your feedback, Great to hear that you are impressed with your Runderwear Briefs and we are pleased to hear that a friend recommended the brand to you. We do hope you love the shorts and do keep us updated with how you get on with these.

Although as a cyclist it is recommended to go commando under your lycra, due to the size of my package I have always found it easier to wear sports support under my lycra (it is not just women who need to wear sports support when doing sports!); I used to wear regular briefs, but of course that wasn't good temperature-wise, but when I found Runderwear at the London-Surrey 100 Registration event I was keen to try your product.
I'm pleased I did as it does everything your claims promise it will do, and I am very happy to promote your products to not just runners but to other sports people too. Your product may cost a little extra, but it is absolutely worth the money.
Thank you for your feedback, Some great medals that you have on and great achievements too! Great to hear that you are loving your Runderwear Briefs and they do everything that you had hoped they would. They are a favourite for many and I am sure you can understand why.
