Super Pants

"The best underwear I think I’ve ever worn. Comfortable and light. They are my new super pants for my weekend long runs. I’ll definitely be investing in more of these for my summer training and races."

Natural Anti-Bacterial Properties - Merino wool naturally absorbs moisture and can absorb up to 3 times its own weight, resulting in less sweat on your body. Merino even absorbs the odours from sweat meaning that you can wear merino wool for several days without the need for washing – perfect for those competing in ultra-distance racing. 

Natural Temperature Control – Merino wool ensures you stay at the optimal temperature – warm in cold, harsh environments and cooler when the temperature rises.

Seamless Design - 360 degree seamless design, resulting in no side seams for ultimate comfort and chafe-free running. Flatlock fine-stitching means that edges are flat, eliminating irritation and rubbing.

Just the best rundies you can buy

these are quite simply the best running underwear item that you can buy and that i have owned and tried. they will last and last as a high quality high performance but of kit, the merino is a great addition to running briefs as it helps wick away and keep you dry. i've used these for marathons and ultra marathons and the performance levels as against other underwear over these distances are superior. there is a lot of great running underwear out there now, but if i was to hands down be asked for 1 recommendation only it would be these. yes there are expensive (the 3 pack makes them almost affordable...) but you get the sense of why they are after using them for a while, and as i say, they will last so the overall investment cost is probably better than inferior product and when you factor in comfort, well, who wouldn't pay any price for that. they feel great, no itching or scratching or chafing and wash up well. just the best rundies you can buy imho.

Thankyou for your lovely feedback, Great to hear that you are loving the Runderwear Merino Briefs and they are the best that you have tried. We love to hear this! Thankyou for your purchases with Runderwear!

Freed from lubricant

So, with a degree of trepidation, I went lubeless……..ultra training, long runs and no Vaseline, super lube or other greasy paste on my bits!
I’ve completed a 65 mile training week, 2 twenty milers in successive days….with my runderwear merino briefs.
I’m delighted…..no chafing, no soreness and no need for any additional products.
As they say in my part of the world… absolutely wheeker!

Thankyou for your feedback, Great to hear that you are love the Men's Merino Briefs and your 65 mile training week wearing these went well. We love to hear it

Somewhat disappointing ☹️

Well made briefs, but do not make it easy for a call of nature as you need to drop them a bit. Not really suitable for casual wear.
Wouldn't buy again or recommend.

Thankyou for your feedback, Really sorry to hear that you did not get along with the Runderwear Briefs. I will pass your feedback onto the team this is greatly appreciated.
