Carhartt expands its summer line with the Sun Defender range, featuring UPF 40+ protection to block over 97% of harmful UV rays.
Workwear manufacturer Carhartt has expanded its apparel portfolio with the launch of the Sun Defender range, a collection engineered specifically to help outdoor tradespeople combat heat and sun exposure during summer months. The core feature of the new lineup is its UPF 40+ rating, which enables the fabric to block more than 97% of harmful ultraviolet radiation, offering significantly higher defence against solar exposure than standard cotton work shirts.
Working outdoors through peak British summer exposes sparkies, roofers, groundworkers, and general builders to severe long-term skin health risks. Traditional heavy-duty workwear often leads to overheating, prompting workers to opt for light cotton tees that provide minimal barrier protection against UV light. The Sun Defender range combines high-level UV filtering with lightweight, moisture-wicking synthetic blends designed to pull sweat away from the skin, ensuring wearers remain comfortable without compromising safety on exposed jobsites.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
Tradespeople looking to stock up on summer workwear will find Carhartt's Sun Defender line priced at a premium compared to basic multi-pack cotton work tees sold at Screwfix or Toolstation. However, the higher price tag reflects functional safety performance rather than just brand badging. Buyers should treat these garments as functional personal protective gear rather than basic clothing. When buying summer kit, trades should check for explicit UPF certifications rather than relying on standard light fabrics, as regular lightweight shirts offer surprisingly low UV resistance once wet or stretched.
When selecting summer workwear for hot outdoor projects, look specifically for certified UPF 40+ or UPF 50+ labels to ensure genuine ultraviolet protection alongside heat regulation.
