Shoyoroll’s ROAN TVT campaign showed a loose, braless rashguard — the opposite of what a no-gi rashguard needs to do on the mat. Here’s the functional case practitioners are making, and why the brand still hasn’t responded.
A rashguard can look flawless standing still and betray you the second you shoot a takedown. Here is a movement-first way to judge no-gi fit — through the reaches, bridges, and sprawls you actually make on the mat.
