At first, I was concerned that the shorts might rise up my thighs when running. My normal Runderwear shorts do this, and they even have a rubber strip along the inside edge of the leg to hold them in place. I was quite surprised to find that the Crossfly boxers didn't do this - they didn't rise at all!ULTIMATE PERFORMANCE & CLEVER ACCESS

For me the 'North Exit' sells this product. Once men experience the ease of use, they won't want to return to their old side entrance boxer. It doesn't feel like I am routing for gold all the time, making it simpler and cleaner.The sportier type who is looking for more support and compression when working out. The Pro 7" Boxer is designed for a wide range of more active sports from football to HIIT.
Eliminates skin on skin friction and chafing providing greater comfort and support.
Easier, faster access when nature calls.
Stays in place however active you are. 4-way stretch construction works with your every movement.
‘No Show’ Dual layer protects against excess drips and moisture.
Anti-microbial and eliminates unwanted smells.

Buy Nice, Not Twice.

Excellent, superb design and the material cannot be beaten. They fit so well and are extremely comfortableAJ Harper - 28/02/22
These boxers are super comfortable for general day to day wear but also for high intensity training and spinning.We are so confident that our socks and underwear are more comfortable than anything you’ve ever tried that we will offer money back guaranteed if you are not satisfied.
We promise you'll love them, or we'll give you your money back.
I find the Pro 7" gives the right amount of compression for a workout, with the added technical benefits of the Crossfly support and fast fly access. The material also seems to dry out quickly.
My husband said they are the most comfortable he has ever had and would highly recommend them.
I spend half my runs adjusting my junk. Not anymore. These are the best running underwear I’ve ever owned. I’ll be ordering more asap. Thanks guys!!!! 🤘
