Men's Running Jock

I am a runner with a lot of miles under my belt (I’ve done 230 marathons and ultras). I can say with that the Rundies I have are the BEST running briefs, after trying countless other options. They are the most comfortable by far, and they have consistently protected me from chaffing under the toughest conditions. I only use Rundies now for my runs!

These are the best I have ever worn. The product description is spot on: durable, smooth, great stitching, very comfortable. Finally, great underwear that actually works for active males. I initially bought them just for training and other active things, but I have since purchased more so that I have enough to use for everyday wear as well. I bought my first set over a year ago and they are still as great as my newest set. I plan to buy again and I would recommend these.

Been using rundies for close to a year and love them.
Best thing I can say is I don't even know I'm wearing them in a marathon, super comfy.
Just ordered some for my wife, and it's not even Valentine's Day.

I bought a rundie a couple of months ago to test it, since with other brands I often suffer from chafing on my long runs (I run 60-70 km per week). No chafing with the rundie, and less odour. So I purchased a couple more today. My girlfriend, who does triathlons, reordered too.

The icing on the cake would be different colours, making it easier to distinguish between hers and mine.

Honestly just bought a pair just to support a good bloke and his dream of opening a successful underwear franchise. However, when I first tried the Rundies on, my package was amongst the clouds. Super comfortable, no sweat, chafing or irritation.
Definitely recommend to anyone, athlete or not, and definitely will be buying more of this product.
Treat your package lads, buy some Rundies.
