The 2UNDR Power Shift Boxer Briefs with their compression-like-feel and Coldskin thermal reduction fabric deliver the highest degree of comfort and support at all times. Their greatest assets, however, are the Joey Pouch that maintains its shape while it keeps you comfortable in the pouch and the Swass Patch for keeping your lower back cool and breezy.

Who Can Make Gains with the 2UNDR Power Shift Boxer Briefs?

The Power Shift Boxer Briefs have been designed with active sportsmen firmly in mind, allowing you to go hard in perfect comfort. They feature 'Coldskin' by Garmatex, which uses crushed Jade minerals woven into the fabric to promote cooling and reduce body temperature when your body starts to heat up during vigorous activity. The Power Shift also offers compression and quick-dry properties, to ensure you're always performing at the highest level. Whether you're on the field, in the boardroom or in the bedroom, this product is ideal for any situation where you need to keep your cool.

All sportsmen will know that skin-on-skin contact combined with vigorous activity and lots of sweating is a recipe for disaster, or at least, lots of chafing. The 2UNDR range prevents this with the innovative 'Joey Pouch', so you can focus on your performance without worrying about discomfort. Once you've tried these boxers, you won't want to go back!

The innovatively added Swass Patch, however, takes care of a completely different problem. The Swass (a clever portmanteau of "sweaty" and "ass") is a lower back ventilation system that keeps your behind nicely chilled and free of those annoying sweaty patches. 

Features of the Power Shift Boxers

  • Four-way stretch fabric for unmatched mobility
  • Premium 40mm moisture wicking waistband 
  • Signature quick access front fly
