I am a Brazilian jiu jitsu practitioner, and this is my favorite rash guard. It has held up well in 2-4 days per week of training and it shows few signs of wearing out anytime soon. I love the side vents in the underarms. I cannot say if it truly makes a big difference, but it certainly feels much better. The only complain I have is that the hem of one sleeve is coming undone quite rapidly. This is no problem to me because I can fix it easily, but I would have preferred it need a bit longer before necessitating repairs.
