Frequently Asked Questions

Is the ISUSI Flow Polo suitable for team uniforms?

Yes, it is widely used for sports teams, work crews, and promotional uniforms. Custom embroidery and printing are available.

What makes i-cool polyester different?

It is engineered for moisture-wicking, breathability, and fast drying, making it ideal for Australian conditions.

Can I add my company logo?

Yes. NS Promo offers embroidery and DTF printing services for all ISUSI polos.

What colour options are available?

There are 10+ colourways including Black Aqua, Navy Yellow, Charcoal Lime, and Ash Black.

What colour options are available for ISUSI polos?
ISUSI polos come in a wide range of on-trend colour combinations, carefully matched to business colours and logo palettes. From bold hi-vis contrasts to smart corporate tones, there’s a style to suit every workplace. Just like Big Bee polos, they are designed with logo-ready panels and long-wear fabrics, so whichever you choose, your team branding looks sharp.
Why are ISUSI contrast polos so popular?
ISUSI contrast polos are one of the most in-demand styles in the Australian market. Their dark contrast panels frame logos neatly for embroidery or digital print, while hiding marks in high-wear zones. This makes them practical and professional. Like Big Bee polos, they are built to last, but ISUSI adds trend-driven designs tailored for uniforms and team branding.
What makes ISUSI polos different from regular work polos?
ISUSI is the sub-brand of Big Bee, designed with a more professional edge. All ISUSI polos use specially selected Cool Dry fibres that wick sweat and keep you fresher for longer shifts. While Big Bee polos already deliver durable fabrics and logo-ready panels, ISUSI takes it further with performance fibres for teams who want extra cooling and a polished finish.
Can logos be added to panel polos?
Yes. Panel polos are designed with darker sections that frame the logo area neatly. This ensures embroidery or printing looks sharp and stays readable across all sizes.
Are Cool Dry polos good for hot or humid conditions?
Yes. Cool Dry fabric wicks sweat away from the skin and dries quickly, keeping you cooler for longer. This makes them ideal for summer worksites, delivery jobs, and outdoor events.
What is the difference between hi-vis polos and standard polos?
Hi-vis polos use bright colour blocks and reflective details for better visibility, while standard polos are designed for everyday team or casual wear.
Can all Big Bee workwear products be customised with digital print and embroidery?
Yes. All Big Bee workwear garments are designed with logo-ready panels that suit both digital print and embroidery. Whether it’s polos, shirts, hoodies or jackets, our fabrics and layouts ensure your branding applies cleanly and lasts through repeat wear and washing.
