If there was ever a revolution in powerlifting gear, the METAL Jack line is it.
All components of the Jack briefs are made of a very thick poly material, thicker than the Ace material. This stuff feels like armor.
The hip seams are sewn at a higher angle than any other Metal briefs, allowing for more hip and leg support and also serving to make squats look deeper.
The legs are angled out even more than the Ace briefs. This is an entirely different cut, utilizing entirely different stitching to provide insane amounts of support.
These briefs will stop you in the hole and provide rebound. One look at the stitching on the crotch, legs, and butt lets you know that this is a new breed of gear.
Due to past sizing issues, we made sure the legs of the Jack line were comparatively bigger. The sizing of the Jack gear will be similar to the Ace gear, but with the legs cut a size larger. This means you should be able to order the size your measurements dictate instead of having to buy one size up, as many people did with the Ace line.
