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.

If you're packing as a Cyclist...!

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.

Fab shorts in the rain

Quite possibly the best wet weather shorts I've ever worn 👍
I ran a 20mile trail run in the rain in these shorts - they didn't snag on the gorse bushes, I ran through waist high ferns and got completely soaked, but a quick brush down and the excess water ran off. Best of all, after several hours of running there was no signs of chaffing. Quick drying too - of course the rain stops in the last mile of the run, and the shorts start to dry out straight away.
Well done runderwear on producing a great pair of shorts.

Great to hear that you are loving the Ultra Light Shorts and they are the best that you have tried! We love to hear that you were chafe free on your 20 mile trail run in the rain and they were quick drying!

Excellent product, wasteful packaging, pricey

First of all, I am a massive Runderwear fan. No other product I have used has worked as well as them. The single loss of star is down to a couple of issues. In this modern climate, wasteful packaging needs to be addressed. A 3 pair deal came in 3 separate packages, each in a cardboard box and each in a zip-lock plastic-type bag. They are only undies! They don’t need to be so well packed in my opinion. The second is the cost. £16.20 per pair of undies is extreme. I know, I know. Nobody forced me to buy at that price and I still did but only because my last pair of Runderwears finally gave up the ghost after years and years. They have been well passed their best for months and months so I had to. If they were just a little cheaper, I would buy them more often so, in the end, be paying more into the coffers. At this price, I won’t be buying again until I have literally a piece of elastic around my waist, like the old pair in the bin. Still, excellent product.

Thankyou for your feedback, Great to hear that you love the Runderwear Briefs.

We are looking into packaging at this moment in time so all feedback is appreciated and taken on board. Our Briefs our priced in line with our competitors and our main aim is to have everyone chafe free and comfortable for many miles! We are always more than happy to help if you have any queries.

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.
