Poncho’s Blue Bison is a performance flannel that leans more technical than a standard button-up. It’s a medium-weight shirt aimed at durability, with stretch for easier movement. Poncho also claims the fabric wicks moisture and dries fast, which matters when you’re layering up early and still end up damp by midday.
Details are geared toward fishing days, with a built-in lens cloth and a sunglasses holder, plus a hidden zippered pocket for small essentials.
Choose Regular for a roomier feel. Slim trims it down through the body. If you want a crisp, non-stretch woven shirt, this isn’t that.
