What is Runderwear™?

Runderwear is the original performance underwear for running. Our mission is to eliminate the discomfort caused by ill-fitting underwear and clothing and create performance running underwear, basewear and socks that are supremely comfortable and chafe-free.


Chafe-Free Guarantee

Runderwear’s whole ethos is about creating chafe-free performance clothing. Runderwear clothing has no side seams and is label-free to prevent irritation and rubbing. Runderwear technical fabric is extremely soft, breathable and highly effectively at wicking sweat away from the body, ensuring you remain chafe-free in ultimate comfort, no matter how many miles you run.

Seamless Design

All Runderwear clothing is created on a 360-degree machine that means no side seams for ultimate comfort and chafe-free running. Flatlock stitching means that edges are flat, eliminating irritation and rubbing and minimising VPL.

Moisture Wicking

The Runderwear technical Polyamide and Elastane fabric is lightweight and well-known for its highly effective properties to remove sweat from your skin, eliminating any irritation and ensuring you keep dry and can run chafe-free.

Runderwear Long Boxer

Excellent product

The Anti Blister Low-Rise Running Sock

Best Socks for Trail Running

Wore a pair during Oman Desert Marathon, only changing to a clean pair on day 5. No excessive sweating (even with the double layer) and no blister even after wearing them for almost 100km in very hot (above 40C) running condition and soft sand.
Also that double-layer gives an extra cushioning making them very comfortable for long runs on rocky trails.

Awesome Base Layer recommended for training in fresh to very cold environment

Tested the baselayer while running for 4 hours by -10C with only 1 extra layer to protect me from the wind and it kept me warm all the way. I also like to wear it for my early morning running session in the fresh Dubai winter and I don't feel to warm as it is very breathable and wicks moisture.
