Hayabusa Grappling Shorts Core – Dark Green

The Hayabusa Men's Core Grappling Shorts are specifically designed for no-gi grapplers and MMA fighters who want shorts that feel lightweight, offer maximum breathability, and move effortlessly during scrambles. Featuring an ultralight fabric, laser-cut ventilation, and an adjustable waistband with a channeled drawcord, these shorts offer a secure fit, tear resistance, and the freedom of movement that grappling demands. Designed for performance, built to last.

Features

• Ultra-lightweight fabric that moves effortlessly during scrambles on the mat
• Performance-oriented cut, specifically designed for fluid, high-level no-gi grappling
• Laser-cut ventilation for maximum airflow under pressure
• Adjustable waistband with channeled drawstring for a secure, custom-fit
• Moisture-wicking, quick-dry fabric that keeps you cool and comfortable
• Reinforced flatlock seams and tear-resistant design for long-lasting use
• Available in four classic colors

Usage

The Core Grappling Shorts are specifically designed for Brazilian Jiu-Jitsu and MMA training. They are ideal for:

• No-gi BJJ training and open mats
• Submission grappling and wrestling
• BJJ competitions and tournaments
• Rolling sessions and technical drills
• MMA grappling training
• Cross-training with a focus on grappling

The grappling-specific cut differs from regular MMA shorts: the legs are tailored more snugly around the thighs to prevent your training partner from grabbing them, while maintaining maximum hip mobility for guard positions, sweeps, and takedowns.

Material and Construction

The shorts are made from 190 GSM fabric, consisting of 90% polyester and 10% spandex. This blend is a deliberate choice for grappling: lighter than traditional fight shorts fabric, with just enough stretch to follow every movement without losing its shape. The fabric has moisture-wicking, quick-dry properties that keep you cool and dry during intense rolling sessions. The reinforced flatlock seams prevent skin irritation and provide the extra durability you need in the areas subject to the most wear and tear.

Grappling-Optimized Cut

The Core Grappling Shorts feature a tighter, more athletic cut than regular fight shorts. This means less loose fabric for your partner to grab, and a silhouette that moves with your body rather than against it. The targeted fit helps you move fluidly during scrambles, guard passes, and transitions, without your clothing slowing you down or distracting you. For serious no-gi practitioners, this is a crucial difference from traditional MMA shorts.

Locked-in Fit

The adjustable elastic waistband features a channeled drawstring. This drawstring runs through a channel inside the waistband and can be secured to a precise fit. The result is a secure, personalized fit that won’t come loose during rolling or scrambles. No more having to pull them up or down between techniques—you stay fully focused on your grappling.

Ventilation

The laser-cut ventilation panels are strategically placed to provide maximum airflow where you sweat the most. This keeps you cool and dry during long training sessions and competition prep—a big difference from standard shorts that trap sweat after just a few minutes.

Size Guide

The Core Grappling Shorts are available in five sizes. Use the guide below based on your waist size:

• Small – waist size approximately 71–76 cm
• Medium – waist size approximately 76–84 cm
• Large – waist size approximately 84–91 cm
• X-Large – waist size approximately 91–99 cm
• 2X-Large – waist size approx. 99–107 cm

These shorts have a tighter fit than traditional fight shorts. Not sure which size to choose? Go with the larger size if you have muscular thighs or prefer a slightly looser fit.

Who are they for?

These shorts are designed for beginners, intermediate, and advanced BJJ practitioners and grapplers. Beginners appreciate the simple, lightweight fit during their first no-gi sessions, while intermediate and competitive athletes choose the Core Grappling Shorts for their grappling-specific features and lightweight comfort. They’re also popular among MMA fighters looking for grappling shorts for their no-gi training in addition to their regular fight shorts.

Difference from MMA fight shorts

While MMA fight shorts often have a wider, more boardshort-like cut for full leg mobility—including high kicks—grappling shorts like the Core Grappling are cut more snugly to minimize your partner’s ability to grab you. The lighter 190 GSM fabric also offers more freedom of movement and ventilation during ground work. Do you train exclusively no-gi? Then grappling shorts are the better choice. Do you combine striking and grappling? Then a versatile MMA fight short like the Hayabusa Core or Apex line is a more suitable alternative.

Care

The Core Grappling Shorts are easy to care for. They’re machine washable and can be tumble dried—no fuss. Wash on cold with similar colors to keep the color and print looking fresh for a long time. Avoid bleach and wash the shorts inside out to protect the prints and finishes.

Color Options

Available in four classic colorways:

• Black – timeless and versatile, goes with any rash guard
• Red – a bright, eye-catching color for those who want to stand out
• Blue – sleek and professional
• Green – modern, sporty look
