Purists may scoff at the idea of a high-performance materials company doing denim, but it's hard to ignore anything Schoeller puts their stamp on. Mission Workshop is using the Swiss company's technical denim that features four-way stretch, breathability, a water-resistant DWR coating, moisture management, and their incredible ColdBlack technology that is much better at managing heat with dark colors. Thermal radiation is bounced right off the shirt and it's also got UPF 30+ protection from the sun.
