You didn't come to the mat to look average. You came to pressure pass, hunt submissions, and represent the USA while doing it. The USA World Cup Rash Guard by Nation Athletic is designed for competition, training, and everyday drilling by grapplers who train like they mean it — and want a rash guard that can keep up without riding up, falling apart, or letting you down at the worst possible moment. You know the moment.

Key Features
- Performance Fabric
Soft, stretchy, moisture-wicking material designed to manage sweat and regulate temperature during no-gi training. Working hard so you can focus on not getting submitted. No promises on the second part. - Flatlock Stitching
Reinforced flatlock seams that reduce irritation, abrasion, and seam failure during rolling and scrambles. Built to survive your training partners — including the one who goes 110% every round and calls it "just drilling." - Breathable Construction
Lightweight fabric that promotes airflow during high-intensity rounds and extended sessions. Staying comfortable on the outside — what's happening on the inside is between you and your cardio. - Secure Compression Fit
Athletic compression that provides support while allowing full range of motion. Stays put through takedowns, scrambles, and the moment someone grabs your collar in no-gi like they've never heard of the rules. - Silicone Waistband Grip
Internal silicone waistband that prevents the rash guard from riding up during training. Unlike your guard, this stays in place. Every single time. - Sublimated Graphics
Fully sublimated USA World Cup design that won't crack, peel, or fade with repeated use. The design will outlast your cardio. Guaranteed. - Antimicrobial Properties
Moisture-wicking fabric that helps reduce odor buildup after intense training. We said helps. Wash it after every session anyway. Your training partners will thank you. Silently. From a distance.
Built for the Mat (Not the Couch)
Built for daily no-gi training, open mats, and competition prep. The fabric resists wear from constant mat contact while maintaining flexibility and comfort through repeated sessions — including the extra round you agreed to because you couldn't tap to your own ego.
Fit & Construction
Compression athletic fit that stays secure during movement. Flatlock stitching minimizes skin irritation, and the cut and sleeve length are optimized for grappling performance and prolonged wear. Run slim — size up if post-training burritos have been a recurring commitment lately.
Competition Suitability
This rash guard is built for competition-level use. Durable performance fabric, reinforced flatlock stitching, and a secure compression fit designed to withstand high-intensity scrambles, constant friction, and extended match time. Stress tested during live training and competition rounds by experienced athletes — including black belt competitors — to ensure durability, fit stability, and performance under pressure.
Please note: This product is not IBJJF approved. Athletes competing in IBJJF events should wear IBJJF-compliant gear as required by the event. We know. We're sorry. The design is still fire.
