FEATURED CUSTOMER REVIEW

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

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

Moisture-Wicking

The technical fabric has excellent moisture-wicking properties to remove sweat from your skin quickly. It has been extensively researched and tested to maximise performance, helping you stay dry and comfortable - even during the most intense exercise

Moisture-Wicking

Breathable Fabric

The performance fabric is lightweight and breathable, with carefully positioned micro-perforations incorporated into the design of each underwear style. These maximise airflow and optimise core temperature control, helping you to stay cool in any conditions

Breathable Fabric

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
 

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.

They rub…

If you’re between the brief and boxer, go for the latter. The brief does still cause chafing and the fit is a bit awkward.

Also a bit naughty that these have now been reduced further after the initial Black Friday sale.

Thank you for your review, I am sorry to hear that you did not get along with the Briefs and you have experienced chafing. Please pop me an email at hello@runderwear.com where we will be able to help with any sizing queries.

Too loose

Sadly (because I like the product) the small size is just too loose. If you could start to make an XS that would actually fit a 30" waist, that would be great. I'm sure I can't be the only runner who is this size.

Thank you for your feedback, I am sorry to hear that the Small are just too loose for you, I will pass this feedback onto the product team to be reviewed!

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!
