Learn how to choose the right size and layer the tokidoki x Hyperfly Skull Rash Guard for grappling, with practical tips for wearing and caring for your gear.
Quick answer
Choose your usual size for a snug, second-skin fit that stays in place during grappling. Wear the Skull Short Sleeve Rash Guard as your base layer under a gi or shorts, and always follow the care label to protect the print.
Why a snug fit matters for grappling
A loose rash guard can bunch up, shift, or give your opponent extra fabric to grab. The tokidoki x Hyperfly Skull Rash Guard is designed as part of a grappling collection, so it should fit close to the body without restricting movement. If you're between sizes, size down for a competition-ready fit or size up if you prefer a little more room for casual training.
Layering options for different training days
This short sleeve rash guard works well as a base layer under a gi jacket, or on its own for no-gi sessions. For extra warmth or sweat management, you can wear it under a t-shirt, but keep in mind that too many layers can affect mobility. In hot weather, the short sleeves help you stay cool while still protecting against mat burns.
How to size, wear, and care for your Skull Rash Guard
- Check the size chart: Measure your chest and waist, then compare to the size chart on the product page. Common mistake: guessing your size based on t-shirts. Rash guards should fit tighter than everyday clothing. If your measurements fall between two sizes, size down for a snug fit.
- Try it on with your training gear: Put on the rash guard and then your gi or shorts. Raise your arms and shadow grapple to check for restriction. Common mistake: trying it on over a bulky shirt, which gives a false sense of tightness. The rash guard should lie flat against your skin without wrinkles or excess fabric.
- Layer it correctly: Wear the rash guard as your first layer. If you wear a gi, put it on over the rash guard. For no-gi, pair it with shorts or spats. Common mistake: wearing a cotton t-shirt underneath, which soaks up sweat and causes chafing. Always keep the rash guard as the base layer for moisture-wicking.
- Wash after every session: Turn the rash guard inside out and machine wash cold with like colors. Avoid fabric softener and bleach. Common mistake: leaving it in a gym bag, which encourages bacteria growth and odors. Hang dry immediately after washing to maintain shape and print.
- Air dry away from heat: Hang the rash guard to dry in a well-ventilated area. Do not tumble dry or iron the printed design. Common mistake: drying on high heat, which can damage the elastic fibers and cause the print to crack. Store folded or hung once fully dry to prevent mildew.
