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!"

Adam S., UK

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.

Ergonomic Fit

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.

Chafe Free

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

Seamless Design
 
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.

Best running under garments I've ever owned

I bought 1 pack at the start of my marathon training as I had been having issues with soreness and general uncomfortable running underwear, I cam across these and thought I'd give them a go based on receiving discount through a strava challenge. I'm sooooo glad I bought a pack and have even gone back for seconds as these are honestly the best running underwear I've ever owned! They are comfortable and I've not had any chaffing problems with any run no matter how long or short since I've been wearing these! I would highly recommend them to anyone that is looking for some quality running underwear.

Thankyou for your lovely feedback this is greatly appreciated! Great to hear that you are pleased that you made the purchase, They are a favourite for many and I am sure you can understand why. Great to hear that you are chafe free and would highly recommend to anyone looking for quality underwear! Happy Running.

I have now had several runs and one 10k race in my new Runderwear briefs. I have noticed and appreciated a qualitative difference between them and the cheapo supermarket briefs I've been wearing for ages. No More That Flaccid Elastic.

Great to hear that you are loving your Runderwear Briefs and you have noticed a difference since wearing these in comparison to your other pairs, We love to hear this.
