Theo said: Great product

Used this for my first half marathon race, really pleased with the quality and the comfort and dryness it provided. I’ve only just started using it, so not sure of endurance and life time, but judging by other reviews, with typical care it is definitely worth the investment.

James S said: Comfiest pants ever!

Brilliant pants. No rubbing or chafing on any length of run. Couldn't recommend highly enough!

Nick OShaughnessy said: Comfort at last!

This product is a-mazing! Really comfortable, excellent fit and best of all NO chaffing!! These are like nirvana in a boxer or pant ( I have both! ) Can’t speak highly enough of these products. You will not regret your purchase and if you have chunky thighs like mine this product is a game changer!!!

matt arnold said: Marvellous Merino

All I can say as to how good these nix feel to run in is that I am now seemingly spending all my spare time trying to source a quality unlined pair of shorts to wear over the top?

With leggings in the cold they are superb and I just want to lose that "extra liner" feel of wearing my runderwear with conventional liner shorts! But as the most comfortable fit ever? Yes undoubtedly this is true and I will be back for many more pairs I can see that!

If someone wants to post any suggestions please feel free? Salomon do a pair of unlined running shorts and they are pricey!

Perhaps Runderwear should get onto that too?

Mark Cox said: Honestly shocked

Honestly shocked how good these are I am so impressed. I brought two weeks prior to doing London marathon 2018 and did one long run in them and they were so comfortable. Ran London in them and had no issues I will no longer go anywhere else for my underwear.
