NYK53 | New York Nicks No-Gi BJJ Rash Guard | No-Gi Training | Nation Athletic

Started this brand in NYC after moving over from the UK. Different cities, same energy, slightly unhinged. The closest thing I’ve found to a Saturday football away day chaos is a packed subway car after a Knicks win.

NYC became a second home. This drop is for that feeling.

 The NYK53 New York Nicks Bjj Rash Guard Limited pre-order only.

Note: Color may vary slightly based on lighting. Your confidence, however, should not.

Pre-Order Notice: Some sizes are currently on pre-order. Please allow 4–6 weeks for delivery on pre-order items. Yes, we know. We're working on it. Breathe through your nose like your coach told you.

Key Features of the NYK53 Rash Guard

• Performance Fabric
  Soft, stretchy, moisture-wicking material that manages sweat and regulates temperature during no-gi training. Because showing up drenched before the first round is a personality, not a strategy.
• Flatlock Stitching
  Reinforced flatlock seams that won't blow out mid-scramble. Unlike your gas tank at the 6-minute mark.
• Breathable Construction
  Lightweight fabric promotes airflow during high-intensity rounds. Smells better than the gym bathroom. That's a low bar, but we clear it.
• Secure Compression Fit
  Stays put during takedowns, guard passes, and that one guy who grabs your shirt every single round even though it's no-gi.
• Silicone Waistband Grip
  Internal silicone grip keeps the rash guard from riding up. Your guard, however, is on its own.
• Sublimated Graphics
  Fully sublimated design that won't crack, peel, or fade. Unlike your confidence after getting triangled by the new white belt.
• Antimicrobial Properties
  Moisture-wicking fabric reduces odor buildup. Your training partners didn't say anything, but they were thinking it. This fixes it.

Built for No-Gi BJJ, Grappling & MMA

This rash guard is built for daily no-gi training, open mats, and competition prep. It handles constant mat friction, sweat, and the existential dread of being stuck in someone's half guard for 4 minutes. Wash it, wear it, repeat until you get your blue belt or give up. (You won't give up. Probably.)

Fit & Sizing

Compression athletic fit that stays secure during movement. Flatlock stitching minimizes skin irritation. Cut and sleeve length optimized for grappling performance. Runs slim — size up if you've been stress-eating between rounds or if your lats are finally responding to training. Either is valid.

Competition Suitability

Built for competition-level use. Durable performance fabric, reinforced flatlock stitching, and a compression fit designed to survive high-intensity scrambles, constant friction, and that one match that goes into overtime because neither of you wants to pull guard first.

Stress tested during live training and competition rounds by experienced athletes, including black belt competitors who had absolutely no mercy on it.

⚠️ Not IBJJF approved. If you're competing IBJJF, wear your compliant gear. The Knicks aren't approved for much either, but at least they show up.
