Product Description
The 03011 Warmtex® Base Layer LS is a long sleeve thermal base layer shirt designed for use in demanding work environments and outdoor conditions. It functions as a thermal undershirt that sits directly against the skin, providing warmth while actively transporting moisture away from the body. The shirt is built for professionals who work outdoors in cooler temperatures and need reliable thermal performance throughout the day.
Application & Use
This long sleeve thermal base layer top is well suited for construction workers, tradespeople and outdoor professionals who require comfortable insulation during physical activity in cold conditions. The moisture wicking properties help regulate body temperature during active work, keeping the wearer dry and comfortable.
The base layer thermal shirt is also a practical choice for companies looking to provide their workforce with uniform, branded workwear that performs in the field. It is equally suitable as a promotional item at trade fairs, outdoor events or industry gatherings where a functional and wearable gift adds real value.
Logo & Personalisation
The Warmtex® Base Layer LS can be personalised with your own company logo or design. This makes it a distinctive item for staff uniforms, corporate giveaways or event merchandise. Your logo can be applied using a print or embroidery technique suited to the fabric and your requirements. The result is a thermal base layer shirt that carries your brand identity into everyday working environments.
