Premium 155 GSM Cotton Twill for Comfort and Durability

Made from fine-quality pre-shrunk cotton twill, the C91 offers a perfect balance of lightweight comfort and durability. The pre-shrunk fabric helps maintain its shape after multiple washes, so your shirt stays looking professional shift after shift. The soft cotton twill is gentle on the skin and breathable, making it suitable for long hours on site, in the sun, or working under layers.

Whether your day involves climbing, bending, or moving heavy equipment, the C91 holds up to the task without compromising on comfort.

Advanced Ventilation for All-Day Wear

One of the standout features of the C91 is its ventilation system, designed to keep you cool during physically demanding work. The shirt includes underarm cotton mesh vents and a hidden back shoulder airflow vent, allowing air to circulate efficiently. This smart design reduces heat buildup and moisture, so you stay comfortable even in warm weather or high-activity conditions. It’s a feature that sets the C91 apart from other standard work shirts.

Functional Pockets for Practical Use

Functionality is key on any worksite. The C91 comes with twin chest pockets with button-up flaps, giving you space to store essential tools, pens, or small items safely. These pockets are strategically placed for easy access, helping you stay organised and efficient throughout your shift.

Maximum Visibility with Hi Vis Safety Features

The C91 is built for both day and night use, meeting the latest Australian Hi Vis safety garment standards:

AS/NZS 4602.1:2011 – High-Visibility Safety Garments

AS/NZS 1906.4:2010 – Retroreflective Materials

Rated Class D/N, this shirt ensures you remain highly visible in any lighting condition. Reflective tape and the bright hi vis colour enhance your visibility on construction sites, roadsides, warehouses, and other potentially hazardous environments.

UPF 50+ Protection for Outdoor Work

Working outdoors exposes your skin to harmful UV rays. The C91 features a UPF 50+ rating, placing it in the Excellent protection category. This makes it ideal for sun-intensive work, keeping your skin protected while maintaining comfort in warmer weather.
