Armed Forces underwear

Posted on


In every exhibition or race we attend with our Runderwear™ team we meet members of the armed forces with problems.  Servicemen and women all over tell us about their issues with chaffing, and it isn't difficult to see why.

Firstly training in the armed forces is long and tough.  Generally they will be expected to wear full combat gear as well as carry a heavy rucksack and often a weapon too.  There are several problems with this when it comes to Chaffing.

1.  Rubbing where you don't want it to!  If you are carrying so much and wearing full gear you will probably not run the same as if you were wearing a vest and shorts! It will definitely change your biomechanics and running style.  Not to mention moving across rough terrain and up and down hills! This is when you need your underwear to be seamless.  The seams in normal underwear will dig in and rub causing abrasions against the skin.  Our Runderwear™ range is fully seamless - helping prevent chaffing.

2.  Keeping cool! In full gear you will get warm, very warm! This is when you don't need to be wearing classic cotton underwear as this will absorb and hold the sweat.  Our Runderwear™ uses technical fabric that helps wick away moisture and give ultimate comfort.

3.  Durability.  The underwear for a soldier needs to be built to last and work in the toughest environments.  Runderwear™ has been tested in the harshest environment; the Sahara desert during the Marathon des Sabres.  We are pleased to say it passed with flying colours.

We are pleased to tell all of the fantastic servicemen and women that we meet that there is now a solution to their problem of finding the right underwear.

We will continue to work hard to make the best underwear in the world and help make members of the armed forces aware of the solution we have created.

Healthy regards,

Richard Edmonds || Co-Founder || Runderwear™

These socks are the best running socks I have ever purchased

Good service, product is fit for purpose

Service is great, and the boxer shorts are good for running and so the job they are designed for. Little disappointed that they are not ethically sourced, they have a cheapish feel to them which was a surprise.

Thank you for your feedback Duncan. Runderwear's range of seamless underwear has sustainability benefits over cut and sew garments by reducing wastage of fabric at manufacturing stage. We are testing new fabrics that have been made using sustainable fibers and aim to bring these into our range in the near future. All our factories are quality control checked to the highest standard and our small team regularly visit them and are satisfied that working conditions are ok. We are somewhat surprised you find the pants have a cheapish feel to them. But maybe you mean that the material is not thick and when you stretch it and look up-close it has an almost gauze-like appearance; this is the nature of the product and gives it the moisture wicking properties. We hope you will like using them and will realize how comfy they are.



Super comfy and stay in place. U.K. size 10 and ordered small.

Women's Running Long Shorts

At last... chaff free running.

Had just about given up with the belief there were running shorts out there that don’t chaff. Purchased the long shorts, and have to say they are wonderful. They are stable, breathable, comfortable and total chaff free.
I would like to highlight I was under the impression that these were “proper” shorts, however they could possibly be described as a base layer shorts. Some form of lightweight run shorts are recommended to wear over them to cover your modesty. Wearing my lightweight run shorts over the top of them didn’t detract from the long shorts benefits.
I typically run up to 21km.
