What is the benefit of underarm or back vents?
Vent panels improve airflow and reduce body heat while working. This feature helps workers stay comfortable during physical tasks or in hot environments.
Why choose a work shirt instead of a polo?
Work shirts offer a collared, professional style with extra pockets for storage. They are better for tradies and site teams who need durability, more coverage, and a tidier uniform look.

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.
