Best rashguard ever

I absolutely love this rash guard, it is very comfortable. I ordered a M which is usually bigger on me, but it fit perfectly.

Houston Heat Approved

I train at Grind House Fitness/MMA in Houston, TX our gym is currently in a warehouse type setup with no a/c. The Houston heat reaches up to 110 degrees and get mighty uncomfortable at times. This rash guard keeps me incredible cool, even under my gi. I absolutely love it! From reading other reviews, I sized up and I'm really glad I did. I'm 5' 7" (with crazy long arms) about 135lbs with an athletic build and ordered a Large. It is long enough to go tucked or un-tucked, fitted everywhere, and doesn't roll up, incredibly well crafted. Highly recommend.

The best rashguard ever

Three words. Favorite rashguard ever. So much so that I waited 2 years for the restock and bought 3 of them. I know you probably think that I could've just got the mens'/unisex one but I'm rather slim and my shoulders aren't broad, so it always bothered me that the neck and shoulder area on the men's fit was loose on the rashie. This rashguard is my all time favorite. I kinda wish that they kept the mesh paneling under the armpits, but I'm not going to complain too much since the fit is the best. It feels like second skin and I honestly won't wear another Brand's rashguard. Nothing is quite as breathable or form fitting as Virus and it looks sleek as hell. I hope they keep making women's sizing for these rashguards. Ladies, keep petitioning for it! Would love to see some ranked WOMENS SIZING rashguards!
