What Our Gearhead® Experts Are Saying:“This shirt is wild—in the best way. It looks like a vintage Western piece, but it performs like something you'd wear hiking or fishing. Super breathable and stretchy, and that hidden zipper pocket is surprisingly useful.”We never thought we’d find a shirt that makes us laugh and sweat less—but the Sendero x Whataburger Confluence Tech Shirt manages both. This piece brings together classic cowboy styling with a bold Whataburger toile print, while hiding seriously capable performance tech beneath the surface. Constructed from a quick-drying, sun-resistant nylon-spandex blend, this shirt handles heat, humidity, and even an impromptu river dip with ease. The fit is comfortable but dialed, and the concealed chest zipper pocket adds a hit of utility without throwing off the vintage look. Whether we’re road tripping, casting lines, or ordering drive-thru with the windows down, this one’s coming with.
