The useful choice in The Estacado is fit. Regular wears easier for a roomier cut, and Slim trims it down without changing the feature set.
This is Poncho’s long-sleeve western-style fishing shirt. Poncho lists it as breathable, lightweight, and quick-drying, with sun protection, which makes sense for hot weather and trips where you want a shirt that doesn’t stay wet for long. It also uses pearl snaps and western styling, along with the functional details Poncho includes for active use.
If you want a traditional western snap-front, this is that shirt. If you prefer a more technical silhouette, start with the Slim.
