Engineered Comfort for the Hardest Working Professionals

When it comes to Australian worksites, comfort and durability are as essential as safety boots or helmets. RSEA Safety provides premium work underwear designed specifically for tradies, construction workers, warehouse staff, and industrial professionals. Our men’s work underwear range combines moisture-wicking properties, elastic waistbands, and premium materials for superior comfort and breathability throughout the day.

Designed for Worksite Demands

The harsh Australian climate requires underwear that can withstand heat, humidity, and long hours. Our men’s underwear range is purpose-built for industries where comfort, breathability, and endurance are essential to daily performance, including:

  • Construction
    Stay cool and comfortable on-site, even during long shifts in the sun.
  • Mining & Resources
    Durable base layers designed for demanding underground or open-cut environments.
  • Manufacturing & Industrial Work
    Flexible and supportive fits ideal for all-day movement.
  • Transport & Logistics
    Lightweight materials that maintain comfort through extended hours on the road.
  • Warehousing & Distribution
    Breathable, stretch-fit designs for consistent comfort during physical tasks.
  • Trades & Maintenance
    Reliable, moisture-wicking underwear made to handle tough Australian conditions.

Each piece features breathable panels, anti-chafing seams, and fabrics that actively manage sweat to keep you cool and dry. With various styles and price ranges available, RSEA Safety ensures there’s a perfect fit for every worker — from the warehouse to the field, across Australia and New Zealand.



Built for Performance & Comfort

Our work underwear is designed to deliver all-day comfort and performance across every trade. Each piece combines innovative design and quality materials to keep you focused on the job.
Key features include:

  • Moisture-Wicking Fabric:
    Keeps you cool and dry by drawing sweat away from the skin.
  • Elastic Waistbands:
    Offer a secure yet flexible fit for unrestricted movement.
  • Soft, Breathable Materials:
    Promote airflow and reduce irritation during long hours.
  • Anti-Chafing Design:
    Minimises friction and discomfort through repetitive motion.
  • Hard-Wearing Quality:
    Built to handle frequent washing and daily use.

Together, these features deliver the best men’s work underwear experience — combining durability, comfort, and performance that lasts.
