Underwear

Our selection of work underwear and base layers is designed for professionals who face demanding conditions and long hours on the job. These garments provide essential warmth, moisture management, and all-day comfort, and many can be customised with embroidery or print to support your branded uniform requirements.

Ideal for industries such as construction, transport, warehousing, and security, our thermal underwear includes long-sleeved tops, leggings, and briefs from trusted brands like Portwest, Regatta, and Fristads. These base layers feature soft-touch materials, stretch-fit fabrics, and flat seams for added comfort and mobility.  Some styles are also EN Certified Flame Retardant, Anti-Static or Arc Flash protective clothing

Looking to outfit your team? Our in-house embroidery and print services let you add logos or team names to suitable garments — especially thermal tops that may be worn as visible outer layers in some work environments. It’s a great way to stay professional, warm, and on-brand, even in the coldest conditions.
