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.


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.


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.


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.


The Runderwear technical Polyamide and Elastane fabric contain micro-gaps, which provide ventilation and pull moisture away from the body, allowing moisture vapour to be transmitted through the fabric.


Runderwear is ergonomically designed using incredibly soft fabric, to move with your body for ultimate comfort.
