Super comfortable. Can’t believe how cool these kept me through tough workouts. Definitely will purchase more Virus products.

Worked For The Big Guy

At 6’4” 365lbs, ordering any clothing online feels more like online gambling than shopping. I’ve had things not fit well and even worse, I’ve had brands change the quality and design to a point where I’d run through a pair of compression shorts in 1-3 workouts. So I decided to give Virus a try.

The first thing I noticed was the quality of the material, it reminds me of my first pairs of compression back in the day which were seemingly indestructible. Along with the strong stitching, this is something that’s going to hold up whether I’m squatting at CrossFit or hitting the treadmill for an extended period.

The second thing I noticed was this is my first time seeing a draw string on compression. I’ve had shorts in the past that fit great...until I start moving. Before I know it, the waist would be rolling down and I’d look like your friendly neighborhood plumber. You can’t reach down to fix your shorts with 350 on your back. I’m happy to report that these pants weren’t going anywhere. My first WOD in them was a pretty solid test of wall balls, rowing, and deficit deadlifts. I never once had to pull them up.

Lastly, they look dope. Don’t pretend that isn’t important.
