Usage

The Apex Long Sleeve Rash Guard is specifically designed for Brazilian Jiu-Jitsu and MMA training. The rash guard is ideal for:

• No-gi BJJ training and open mats
• Submission grappling and wrestling
• BJJ competitions and tournaments
• MMA sparring and clinching
• As a base layer under your gi for extra comfort and protection
• Cross-training and functional fitness

The long sleeves provide full protection for your arms, which is especially valuable during grappling and mat work. They protect against mat burns, scrapes, and the spread of bacteria, which is essential for hygiene in grappling sports.

Why a rash guard?

A good rash guard is indispensable for BJJ and MMA practitioners. It protects your skin from mat burns, scrapes, and bacterial infections such as staph and ringworm, which, unfortunately, are common in grappling gyms. In addition, a rashguard wicks away sweat, keeps you cool, and reduces the risk of skin irritation caused by friction between your skin and that of your training partner. The long-sleeve version offers extra protection and warmth, ideal for cooler gyms or for athletes who prefer the added coverage.

Material and Construction

The Apex Rash Guard is made from a 200 GSM polyester-elastane blend with four-way stretch. This composition offers several advantages: the four-way stretch allows the fabric to move with your body in all directions, the silky-soft texture feels smooth against the skin, and the quick-dry properties wick away sweat quickly. The reinforced flatlock seams prevent irritation during prolonged contact with the mat or your training partner, and ensure that the rash guard retains its shape after hundreds of rolling sessions.

Locked-in Fit

A crucial detail that sets the Apex Rash Guard apart is its smart closure system. The silicone-lined waistband grips subtly against your skin or your fight shorts, preventing the rash guard from riding up during rolling. The lockdown loop at the hem allows you to attach the rash guard directly to your fight shorts for a fully locked-in, competition-ready fit. No more shirts riding up in the middle of a scramble—you stay completely focused on your technique.

Neck Design

The neckline features a bonded seam construction instead of a traditional stitched hem. This eliminates friction points around the neck, which is essential during grappling techniques such as chokes and collar work. The result is a rash guard that feels comfortable, even during long technical sessions.

Size Guide

The Apex Long Sleeve Rash Guard is available in six sizes, from Small through 3X-Large. Use the guidelines below based on your chest circumference and height:

• Small – chest circumference approximately 91–97 cm, height 1.68–1.75 m
• Medium – chest circumference approx. 97–104 cm, height 1.75–1.80 m
• Large – bust size approximately 104–112 cm, height 1.80–1.85 m

Who is it for?

This rashguard is suitable for beginners, intermediate, and advanced BJJ practitioners, grapplers, and MMA fighters. Beginners just starting no-gi training appreciate the protection against mat burns and skin irritation, while advanced and competitive athletes choose the Apex for its snug fit and modern look. The long sleeves are ideal for athletes who want full arm coverage, for cooler gyms, or as a base layer under a gi.

Differences from the Short Sleeve Version and Core Line

The Hayabusa Apex Rash Guard is available in both short-sleeve and long-sleeve versions. Both models share the same premium features. The choice between short or long sleeves depends on personal preference and circumstances:

• Short Sleeve – ideal for warm gyms and maximum shoulder mobility
• Long Sleeve – ideal for full protection, cooler gyms, or as a base layer under a gi

The Apex further distinguishes itself from the Core line through its modern color schemes (Carbon Black, Ash White, Dusk Blue, Recon Green). Technically, the models are virtually identical, so the choice is purely a matter of taste and style.

Care

The Apex Rash Guard is easy to care for. It’s machine washable and dryer safe, with no hassle. Wash on cold with similar colors to keep the color and print looking fresh for a long time. Avoid bleach and wash the rash guard inside out to protect the prints and silicone waistband. Wash the rash guard after every workout; this is essential for hygiene in grappling sports.

Color Options

Available in four modern colorways:

• Carbon Black – sleek, timeless black for any setting
• Off-White – clean and modern white
• Dark Blue – deep blue with contrasting accents
• Tactical Green – military-inspired green for a rugged look
