Custom Rash Guards & MMA Shorts: A Sublimation Guide for Fightwear Brands

Rash guards and fight shorts are the backbone of every no-gi, MMA and Muay Thai brand. They are worn in almost every training session, they wear out and get replaced, and with full sublimation they are the perfect canvas for bold designs. That makes them one of the best products to launch or grow a fightwear brand.

This guide explains how custom rash guards and MMA shorts are made, what to decide before ordering, and how to work with a custom rash guard manufacturer to get a product your customers will love.

What is sublimation and why does it matter?

Sublimation is a printing process where ink is turned into gas with heat and bonded directly into polyester fabric. Instead of sitting on top of the fabric like a screen print, the design becomes part of the fabric itself.

For fight wear, this has big advantages:

• No cracking or peeling: the design survives stretching, grappling and repeated washing.
• Unlimited colors: full artwork, gradients and photo-quality graphics at no extra cost per color.
• All-over designs: print from seam to seam, including sleeves, side panels and collars.
• Light and breathable: no heavy print layer, so the garment stays soft and stretchy.

Sublimation works best on white or light polyester-based fabrics, which is why most rash guards and fight shorts use polyester-spandex blends.

Part 1: Custom rash guards

Choose the style

• Long sleeve: the standard for BJJ and no-gi grappling. Protects the skin from mat burn and gi friction.
• Short sleeve: popular for MMA, warm climates and summer training.
• Ranked rash guards: colored panels or stripes that match BJJ belt ranks, a strong product for academies.
• Women’s and kids’ cuts: a dedicated fit for women and juniors helps you reach a wider audience.

Pick the fabric

Most rash guards are made from a polyester-spandex blend. The spandex gives a compression fit that moves with the body, while polyester holds sublimated designs and dries quickly. Ask your manufacturer about fabric weight and stretch so you get the feel you want.

Check the construction details

• Flatlock stitching: flat seams that don’t rub or chafe during rolling.
• Silicone waist gripper: keeps the rash guard from riding up during training.
• Reinforced seams: under the arms and at the shoulders, where stress is highest.

Part 2: Custom MMA and Muay Thai shorts

Choose the style

• MMA fight shorts: mid-thigh length with side splits or stretch panels for kicks and grappling.
• Muay Thai shorts: short, wide-leg shorts in satin or polyester with the classic high waistband.
• Grappling / BJJ shorts: streamlined shorts without pockets or zips, often worn with spats.
• Vale tudo shorts: tight compression shorts for grappling and MMA.

Waistband and closure

A secure waistband is essential in fight shorts. Common options include a hook-and-loop (velcro) fly with a drawstring, an elastic waistband with drawcord, or a wide Muay Thai-style elastic band. Choose based on your sport and how your customers like their shorts to fit.

Movement features

• Side splits for high kicks
• Four-way stretch crotch or side panels
• Lightweight, quick-dry fabric
• No pockets or zips that could catch during grappling

Designing your collection

Rash guards and shorts sell best as matching sets. When planning your designs, think about:

• A clear theme: a story, pattern or concept that runs through the whole collection.
• Logo placement: chest, sleeves, back, waistband and leg panels.
• Size range: men’s, women’s and kids’ sizes, so academies can order for every member.
• Team and sponsor branding: academies and fight teams often want names, logos and sponsor patches.

You don’t need finished artwork to start. A good manufacturer can turn your logo and ideas into a digital mockup before production.

Ordering step by step

1. Share your idea: your logo, design ideas, styles, sizes and quantity.
2. Approve the mockup: check colors, placement and details on a digital design.
3. Check a sample: test fit, stretch, print quality and stitching before bulk production.
4. Bulk production: your order is printed, cut and sewn to the approved sample.
5. Packaging and shipping: private label tags, branded polybags and delivery by air or sea.
