So, I purchased the red Viper Shorts and Black Competition Shorts during Black Friday. I hesitated on the Viper Shorts because they didn’t look as flexible as the Competition Shorts. I was right in my hesitation unfortunately. I ordered XL I’m both shorts and the Competition Short are awesome! The Viper Shorts have way less stretch and are a little shorter. The length isn’t an issue but the lack of flexibility and stretch is and I could tell the difference immediately during my workout. I could feel the difference in the materials as soon as I took them both out of the packaging, the Vipers were stiff. I’m 6’, 205 and I coach CrossFit. I wish the same color red would have been available in the Competition shorts. The shipping was great, shirts fit perfect, but I wouldn’t purchase the Viper shorts again.
