Runderwear is a Poole-based running brand, set up around 2013, that makes underwear, socks and bras designed to stop chafing.

About Runderwear
The kit
Men's running briefs and women's running underwear and shorts are the core of the range. Running socks are designed to help prevent blisters, and the sports bras use the same seamless approach for support. Styles come in a choice of colours.
Why seamless matters
Each piece is made from a single piece of fabric, so there are no side seams or labels where friction builds up on long runs. The fabrics are breathable and soft, and the brand says they keep their shape through hundreds of washes, which means fewer replacements.
Delivery and returns
Standard UK delivery takes 2-4 working days, with express available and free delivery above a minimum order value. Unworn items can be returned within 30 days, and if a product makes you chafe while running, the 90-day guarantee gives a full refund. Payment options include Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay and Klarna. Gift cards are sold, students can save through Student Beans, NHS staff can use the Blue Light App, and the brand ships abroad. Runderwear is part of Masters of Mayfair Limited.
Sustainability at Runderwear
Runderwear creates durable, high-quality products designed to last through hundreds of washes, reducing the need for frequent replacement.
