UPF 50+ SUN PROTECTION - Blocks over 98% of harmful UV rays during extended outdoor work. Protection is embedded in the 100% polyester interlock knit fabric, so it won't wash out or wear off over time. Essential for roofers, landscapers, and construction crews.
LIGHTWEIGHT 120GSM INTERLOCK KNIT - 50Dx50D construction delivers a soft hand-feel with 4-way stretch for full mobility. Temperature-regulating fabric adjusts to your body heat so you stay comfortable from morning cool through afternoon sun.
MOISTURE-WICKING FAST-DRY FABRIC - Built-in wicking treatment pulls sweat away from skin and dries fast to keep you cool during 10+ hour outdoor shifts. Outperforms cotton work shirts in hot, humid summer conditions.
JOBSITE-READY DETAILS - Locker loop for easy hanging, drop tail for coverage during active movement, and two reflective eye sights plus reflective logo for low-light visibility. Abrasion-resistant and tear-resistant for daily trade use.
BUILT FOR OUTDOOR TRADES - Engineered for construction, roofing, landscaping, electrical, and utility professionals who need all-day sun protection without overheating. Purpose-built work shirt, not repurposed athletic wear.
