Runderwear is a UK-based performance underwear brand founded by Jamie Smalley and Richard Edmonds, who met at Loughborough University and set out to solve a problem every runner knows: great technical kit on the outside, but ordinary underwear underneath. After Jamie experienced chafing during the New York Marathon, the pair spent two years trialling fabrics and fits with their running club before launching. Runderwear debuted at the London Marathon expo in 2013 and sold out immediately, going on to win "Best Underwear & Socks Brand" at the Running Awards in 2018, 2019, and 2020. Based in Poole, Dorset, the company ships to over 150 countries and remains dedicated to its founding mission: to liberate runners to run free.
Every Runderwear garment is built around a seamless 360-degree weave that removes the seams and hot spots most likely to cause chafing. There are no sticky labels to catch and rub, and the technical fabrics are moisture-wicking, pulling sweat away from the skin to keep friction to a minimum even on long runs. The brand backs this up with a 28-day, no-quibble guarantee: if the underwear causes chafing, Runderwear will issue a full refund. The core fabric blend for running underwear is 92% Polyamide and 8% Elastane, while a Merino wool range uses a mix of ethically sourced Merino, Polyester Thermocool, Polyamide, and Elastane for cooler-weather comfort.
Runderwear offers a comprehensive range for both men and women. The women's collection includes low-rise briefs, hipsters, thongs, and boy shorts, alongside running sports bras spanning cup sizes A through H. The men's range covers boxers and briefs in several cuts. Beyond underwear, the brand produces anti-blister running socks, compression socks, cushioned and Merino wool sock options, running base layers, and accessories. All products are designed using the same seamless, moisture-wicking technology as the core underwear line, so runners can build a fully chafe-free kit from a single brand.
Despite competing against much larger, established sports brands, Runderwear won the Running Awards "Best Underwear & Socks Brand" category three consecutive years running – 2018, 2019, and 2020. The brand is stocked internationally and has built a strong following among marathon runners, ultramarathon competitors, and everyday gym-goers who prioritise comfort. Customer reviews consistently highlight the seamless construction and the no-fuss returns policy as standout features.
Yes. Runderwear Ltd continues to trade and ships internationally from its base in Poole, Dorset. The brand's current range can be found on its official website at runderwear.co.uk and runderwear.com.
Runderwear uses a seamless 360-degree weave specifically developed for running, removing the stitched seams that cause chafing. Combined with moisture-wicking polyamide fabrics and label-free construction, the garments are designed to stay comfortable across distances that would leave conventional underwear causing irritation.
Yes. The brand offers a 28-day no-fuss guarantee. If any Runderwear product causes chafing during that period, customers can request a full refund without having to return the item.
The underwear range is available in multiple sizes for men and women. The running bra range covers cup sizes A through H, with a dedicated fit calculator and free exchange service to help customers find the right size. As a smaller independent brand, Runderwear has acknowledged it is working to extend its bra size range further.
After its triple win at the Running Awards (2018, 2019, 2020), Runderwear continued to expand its product range to include Merino wool options, sustainable recycled-fabric lines, running socks, sports bras, and base layers, growing from a single-product underwear brand into a broader performance kit supplier.
Runderwear recommends machine washing at 40 degrees with similar colours. Bleaching, tumble drying, dry cleaning, and ironing should all be avoided to preserve the seamless construction and moisture-wicking properties of the fabric.
