The useful choice is fit. Regular leaves more room through the body, and Slim trims it down without changing what the shirt does.
Poncho’s Snowcat is a long-sleeve performance flannel meant for anglers who want a softer shirt that still handles work. Poncho rates the fabric as medium weight for durability, with stretch for easier movement. They also claim moisture-wicking and fast drying, which helps when you’re in and out of the boat or dealing with humid days.
Details are fishing-specific: there’s a built-in lens cloth, a sunglasses holder, and a hidden zippered pocket. If you want a true heavy flannel for cold-weather layering, this one isn’t positioned that way.
