Custom Singlets Vs Running Singlets: Key Differences, Benefits & How To Choose

(MENAFN- Market Press Release) September 10, 2026 9:27 pm - Custom singlets and running singlets aren't the same thing. Here's how they differ in fabric, fit, and purpose - and how to pick the right one.

The key difference between custom singlets and running singlets is purpose: "custom singlets" is a broad category covering everyday, workwear, and event singlets in a wide range of fabrics, while running singlets are a specific performance subset built from lightweight, moisture-wicking material and cut for competitive or training use. Every running singlet is technically a custom singlet, but not every custom singlet is built to run in.

If you're ordering for a team, club, or business and aren't sure which category actually fits your need, here's how to tell them apart.

What "custom singlets" covers

Custom singlets is really an umbrella term for any sleeveless, branded top ordered for a specific team, business, or event. That covers a lot of ground:

Hi-vis singlets for tradies and outdoor workers
Classic singlets in standard cotton for everyday or casual branding
Event singlets for fun runs, festivals, or fundraisers
General sports singlets for club and team kit

These are typically made from cotton or a cotton-poly blend, prioritising comfort, print/embroidery compatibility, and cost-effectiveness over specialised athletic performance features.

What makes running singlets different

Running singlets are a purpose-built subset designed specifically around the demands of running, both for racing and serious training. A few features set them apart from a general-purpose singlet:

Moisture-wicking fabric - usually a technical polyester or polyester blend rather than cotton, engineered to pull sweat away from the skin rather than absorb it. Nike's own explainer on the technology describes how moisture-wicking fabric uses capillary action to draw sweat to the outer surface of the garment where it evaporates, rather than letting it soak in and add weight the way cotton does.
Lighter weight fabric - every gram matters over distance, so running singlets use thinner, more minimal fabric than a standard cotton singlet.
Higher-cut armholes and a closer, more aerodynamic fit - reducing chafing and fabric movement during a running stride, which a looser-cut cotton singlet isn't designed to manage.
Quick-drying properties - useful for both hot-weather racing and multi-use training gear that needs to dry between sessions.

This is precisely the kind of purpose-built design our running singlets range is built around, distinct from our broader singlet range.

Why the printing method also differs

This is a detail that trips a lot of buyers up: because running singlets are typically polyester rather than cotton, they don't take screen printing or embroidery the same way a cotton singlet does. Polyester's synthetic fibres don't absorb ink or hold stitching the same way natural fibres do. Dye sublimation - a process that infuses dye directly into polyester fibres using heat - is generally the better match for running singlets, producing vivid, full-colour designs that won't crack or peel during high-intensity wear. A cotton or cotton-blend singlet, by contrast, is well suited to standard screen printing or embroidery.

Benefits of general custom singlets

Lower cost per unit, particularly at bulk order volumes
Wide compatibility with screen printing and embroidery
Versatile across workwear, casual branding, and general team use
Comfortable for all-day or everyday wear, not just short bursts of activity

Benefits of running singlets specifically

Genuine performance advantage for competitive or serious training use
Reduces chafing and fabric drag during a running stride
Better temperature regulation over long distances or hot conditions
Vivid, durable branding via sublimation printing, which won't fade the way some prints do on other fabrics

How to choose between them

A few honest questions usually settle it:

Will this actually be worn to run in, competitively or in training? If yes, a running singlet's technical fabric and fit are worth the extra cost. If it's for general team identity, casual wear, or a one-off event, a standard custom singlet is more cost-effective.
What's your printing budget and method preference? Cotton singlets give you more flexibility (screen printing, embroidery); running singlets generally point you toward sublimation.
How will the garment be used after the event or season? A general custom singlet tends to have broader everyday use; a running singlet is more purpose-specific.

Getting it right

At Garment Printing, we work with athletics clubs, running groups, and general sporting teams across Australia, so we're used to helping people pick between our full singlet range and our dedicated running singlets line depending on actual use. As a 100% Australian-based, customer-focused business, our easy-to-use design studio, no minimum order quantity, and clear pricing with no hidden charges make it simple to order the right garment rather than defaulting to whatever's cheapest. We also offer bulk order discounts for full club or team orders, and try to run our business responsibly on the environmental side too.

Final thought

Custom singlets and running singlets aren't competing products - they're built for different jobs. A general custom singlet covers branding, workwear, and casual use well; a running singlet earns its place through genuine performance features that matter once you're actually racing or training seriously. Matching the garment to how it'll really be used avoids paying for performance features you don't need, or under-specifying a singlet that needs to hold up over a real training block.
