Neon and cyberpunk rash guard: circuits, future cities, and bright colours on the mat
The buying guide in 6 photos. Tap a photo, the answer opens below.

01Why choose a neon or cyberpunk rash guard?
Because it moves past plain black without losing any character. Cyan, magenta, and violet neons stand out against a dark background and make a piece that gets noticed at first glance. Circuit, future-city, and mechanical-armour motifs cover the whole back.
It's also a way of seeing the fight: a well-drilled sequence runs like a program. One condition, one response, one chain, repeated until it becomes automatic.

The printed circuit suits systematic players who think in decision trees and chains. The neon city fits creative players who change rhythm and surprise. The mechanical armour speaks to heavy, methodical pressure players who advance without leaving space. At an IBJJF no-gi tournament, bright colours don't meet the black-or-white base rule: save these pieces for the gym, open mat, and tournaments with no colour code.

03Short sleeve
Every design covers the whole back and wraps around the sides and sleeves, with no empty space.
In BJJ with the gi, choose long sleeves: they protect the arms from jacket friction and don't ride up during guard passes. In no-gi and grappling, both cuts work; short sleeves leave the shoulders freer. In MMA and wrestling, short sleeves are the most common choice.
- Short sleeve, from $65No-gi, grappling, MMA, wrestling. 88% recycled polyester, 12% elastane, sizes 2XS to 6XL.

In no-gi, IBJJF requires a black, white, or black-and-white base, with at least 10% in the belt colour. Check the dominant colour of the design against your tournament rules. At the club, on open mat, and in tournaments with no colour code, they work everywhere.
