Description

The colour that stops being noticed.

The MOSS Core Essentials Rash Guard is the line in deep olive — a no-gi compression layer the colour of ground cover, built to be worn hard and forgotten about.

Why you’ll love it

  • Locked-in compression — 280GSM four-way stretch blend holds position through inversions, shots, and scrambles. No riding up. No re-adjusting mid-roll.
  • Hides the session — deep olive does not show the chalk, sweat and mat grime that make a black top look tired by week three.
  • Flatlock construction — every seam sits flat against the skin. Zero chafing across a two-hour session.
  • Moisture discipline — rapid-wick fabric pulls sweat off the body and dries between rounds, keeping weight and cling minimal.
  • Anti-microbial layer — engineered to resist the bacteria load of high-volume training.

Technical specifications

  • Fabric: 280GSM compression blend — 85% polyester / 15% spandex
  • Construction: Flatlock-stitched seams, reinforced stress points
  • Graphics: Full sublimation — zero surface print
  • Fit: Athletic compression. True to size. Size up for a relaxed fit.
  • Ruleset: IBJJF no-gi compliant base colorway logic

Built for

The daily grind: no-gi jiu-jitsu, wrestling practice, MMA grappling rounds, and competition warm-ups. Wear it under a gi or as your primary no-gi layer.

The Standards

Our Foundation

Durability At Unvext Group, quality isn’t a goal; it is our baseline. Every piece of gear we produce must withstand the extreme rigors of high-level grappling and striking. We prioritize industrial-grade materials and reinforced construction to ensure our gear survives the "grind" as long as the athlete does.
Timeless We believe that true style outlasts the season. Unvext Group adheres to a clean, functional aesthetic that rejects fleeting trends and visual clutter. Our designs are intentionally understated, allowing the athlete's performance to be the focal point.
Evolution While our designs are timeless, our technology is never static. We operate in a state of constant "white belt" humility, always learning and adapting to the shifting needs of the MMA and BJJ markets. We iterate based on real-world feedback from the cage and the mats.
