The useful choice here is fit. Regular gives more room through the body. Slim trims that down without changing the fabric or features.
The Grease Monkey is Poncho’s short-sleeve fishing shirt with the same fit and fabric as their Original. It keeps the layout simple with a single chest pocket, for anglers who want less bulk in the front of the shirt. Poncho positions it as an Ultra-Lite option, and describes the fabric as soft, breathable, lightweight, and fast-drying for staying comfortable through long days in the heat.
