Materials vary by style. Options shown include 100% cotton and a 60% polyester / 40% wool blend.
The caps use several adjustable closures, including a back snap (snapback), a tuck-and-slide (back tuck) style, and a metal strap closure.
Care instructions specify hand wash only, then either line dry or lay flat to dry.
Brim (bill) lengths are listed at 3, 4, and 5 inches across the options; crown height is typically about 4 inches.
The caps include ventilated design elements such as stitched eyelets and breathable fabric panels to promote airflow.
Lining varies by model: some caps are unlined or single-layered, while at least one option is shown with a full lining.
Product details list a fabric type described as “Year Round Fabric Construction” for multiple caps; the wool-blend option is specifically noted as providing extra warmth for cooler weather.
