When it comes to exercise, especially running and walking, the right underwear probably isn't very high on your list when the right footwear, jackets and even hats are prioritised. The problem is, wearing your usual undies can cause chafing, something that's both really annoying and incredibly painful.

It's a good idea to minimise the risk with the best underwear possible which is where Runderwear comes in. Specially designed to minimise any chance of chaffing, the company offer every conceivable type of underwear, from boxers to bras, and hot shorts to socks. They're expertly designed and made, but thanks to the time of year, are available at a discounted rate, perfect for burning off Christmas dinner come January.

Black Friday is over for 2021, but there are some last minute deals at Runderwear to capitalise on.

What is Black Friday and Cyber Monday 2021?
