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

Fabric Composition:

92% Polyamide
8% Elastane 

Product Care:

  • Warm machine wash up to 40­°C
  • Wash with similar colours
  • Do not tumble dry
  • Do not soak, bleach or dry clean

Awesome, supremely comfortable!

Only done 1 run (6km) and one hike (Pen Y Fan, 12km) wearing these, but my god, they're supremely comfortable! The lack of seams means nothing chafes or iritates, and the 'relaxed' area at the front to accommodate the family jewels ensures there's no restrictions where you don't want them.
Just amazing!

Great to hear that you are loving your Runderwear Briefs and love how comfortable that they have been. We are so pleased to hear that you are chafe free and no longer feel restricted!

Thank you for your purchase with Runderwear!

Doesn't fit because of narrow cut

I feel like I wasted my money as I didn't realize that this underwear can't be returned even if you just try it only briefly after taking a shower. I'm not sure how someone is expected to know how the underwear fits if you don't briefly try it on. I would not have expected the cut to be so different from my normal briefs that I wear. Maybe they are expecting tall guys (6' 4") to need a bigger size or something but these don't fit well except for around the waist (so I know I got the correct size per the sizing chart). The front part is so narrow that my junk doesn't fit completely and the back part is narrow enough that it would just bunch up in back when moving in them. I have never had these problems before across several brands of briefs. The material feels nice but that's about the only positive thing I can say about them. Maybe these briefs work for smaller guys but they are definitely not cut right for a tall, slender guy like myself.

Thank you for your feedback, I am sorry to hear that you did not get along with the Runderwear Briefs. Unfortunately we use the same policy as most shops do when it comes to underwear making this non returnable once tried. We have the size guides on the website to follow which ensure you purchase the right size and we are an email away if you need any help with sizing. I will be sure to pass your feedback onto the team as all feedback is appreciated!

Go-to running undies

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.

Believe the hype

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.
