Best Mens Non Chafing Running Underwear

We recently covered the best non chafing running shorts for men here on Many of the recommendations featured in that post were 2 in 1 solutions with lycra or tight-fitting underlayers beneath the ‘outer’ shorts.

However, many of us play sports in team kits and therefore a 2 in 1 shorts solution to stop chafing is not ideal. For those men with no thigh gap, the rubbing and friction in the inside leg can become sore, raw, and very irritating.

Let’s have a look at the best non-chafing running underwear garments on the market at the moment.

Our Pick

Under Armour Mens Tech Boxer Brief

Anything made by Under Armour is designed with sporting performance in mind. These boxer briefs are no different. Made from 90% polyester and 10 spandex, they are always a tight fit, so your privates are supported. We like them primarily because of their breathability and fast-drying, wicking properties.

Unlike cotton which can hold moisture (and ultimately leads to bacteria build-up), these boxer briefs don’t, reducing the chafing risk. You can also see from the image, the leg length is more than enough to cover any thigh gap chafing for those on longer runs.

  • Breathability & wicking ability
  • Fast drying
  • Covers any thigh gap area chafing
  • Size up – the fit can be small.

Runderwear Long Chafe-free Boxer

Surely, the clue’s in the name? A brand called Runderwear exists purely for runners who despise chafing. They’re award-winning too – picking up Gold in the 2018 and 2019 Running Awards for Best Underwear & Socks. The boxer featured here is 92% polyamide and 8% elastane in terms of fabric but has a lengthy 7.5-inch inseam. The detail is brilliant too, or lack of it actually – there are no tags, labels, or dodgy stitching to aggravate the runner (it’s flat lock stitching).

Rest assured, they won’t ride up either, this is thanks to a pair of subtle silicone leg grippers that hold the boxers in place as you get on with your exercise.

Our Pick

Icebreaker Anatomica Boxers

Icebreaker are usually synonymous with excellent base layer technology. Well, underwear is actually a base layer and as Icebreaker have used their technical prowess in manufacturing these boxers, they are a worthy inclusion in this ‘best of’ list. The inside seam is 5.5 inches which will prevent runners chafe.

The fabric is their own ‘cool-lite’ blend, using the finest New Zealand merino wool blend which is odour resistant and anti-bacterial. They’ll withstand multiple washes too, Icebreaker weave a nylon thread into to the merino for extra strength. It’s a snug fit too, thanks to 5% elastane in the mix.
