Our Matrix Shorts has a little bit of the old with some new additions. It still has an amazing 4-way stretch technology. The fabric stretches four ways to make it the most comfortable and mobile short around. We also added a new smaller strap that flaps over the top, so there is no irritation with high volumes of squats. The Shorts also have a slimmer cut then our older shorts, which helps with chafing.
