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!

  • Fabric: 85% polyester / 15% spandex

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 Pro 7" Boxers are not only packed with features to enhance support and comfort; they are also ultra breathable and sweat wicking. Take a look at our reviews to see why these boxers are the ultimate workout partner.

  • COCCOON™

    Eliminates skin on skin friction and chafing providing greater comfort and support.

  • X-FLY

    Easier, faster access when nature calls.

  • ZEROFOLD 360

    Stays in place however active you are. 4-way stretch construction works with your every movement.

  • DRI-PX2

    ‘No Show’ Dual layer protects against excess drips and moisture.

  • Stay Fresh

    Anti-microbial and eliminates unwanted smells.

  • Breathable

    Breathable mesh panels get rid of moisture and dries fast for maximum comfort.

  • Planet Friendly

    Buy Nice, Not Twice.

Peter Cordwell 20/12/21

Excellent, superb design and the material cannot be beaten. They fit so well and are extremely comfortable
This style is true to fit.

An athletic fit with a 7-inch inseam so they sit higher on your hips a little higher to offer more support. And of course, the ZeroFold Waistband ensures it stays in place.

AJ Harper - 28/02/22

These boxers are super comfortable for general day to day wear but also for high intensity training and spinning.
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.

Great for the Gym!

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.
