What are Tactel Nylon Fibers?
Tactel™ nylon is an advanced performance fiber used in Roark’s Bless Up Shirt, designed to be ultra-lightweight, breathable, and incredibly soft — delivering the comfort of cotton with the durability and quick-dry functionality needed for life on the road. It’s up to 20% lighter than traditional fabrics, dries eight times faster than cotton, and resists wrinkles, making it ideal for hot, humid conditions and minimalist packing. The microdot weave enhances airflow and moisture-wicking, keeping you cool and dry whether you're trekking through the tropics or navigating an urban layover.
What is Mechanical Stretch?
Mechanical stretch is a type of built-in flexibility achieved through the fabric’s weave rather than added elastic fibers, allowing it to move naturally with your body without sacrificing breathability or structure. In Roark’s Bless Up Shirt, the mechanical stretch is engineered into the microdot nylon construction, delivering enhanced mobility, all-day comfort, and lasting durability — ideal for active travel, warm climates, and life on the move.
