The Venum Razor Rashguard is essential for your grappling BJJ or even bodybuilding training. It provides excellent support thanks to its elasticity: a second skin effect. Its compression system operates over the entire surface of the t-shirt and its mesh inserts allow rapid evacuation of perspiration. Stylist Tip: Rashguards have very tight cuts. If you want to be more comfortable we advise you to take one size more than you take for a classic compression top.
