Nobody really knows what happened to the dinosaurs… but we’ve got a theory. This Button Up explores the idea that aliens rolled in, scooped up a few dinos, and left the rest of us to ride bikes and ask questions. This is for those of you who wonder what’s really out there beyond the berm.

VERSITILE
Wore this on a ride and then straight to a brewery. No complaints. It's lightweight, stretchy, and still looks great after sweating in it!

GREAT QUALITY SHIRT

Fit is true to sizing and is neither a loose or tight fit. Material seems robust but I have not tested it through many washes yet.

THE BEST SHIRT EVER?

This shirt is perfect for any occasion. Going to a wedding? Done. Going fishing? Done. Going riding with the crew? Done. It checks all of the marks. Best of all, it is breathable and very stretchy.

Why We Made Technical Button Ups

We ride in what we like to ride in… simple as that. One summer, we found ourselves riding in short sleeve button up shirts we’d found in our grandpa's closet. As we rode we realized that the collar keeps the sun off of our neck, the buttons can be undone to provide more airflow, and frankly it was a blast to add a little more style to our adventure. The only negative was the heavy weight cotton material.

With that in mind, we crafted the first ever, Jersey-Style Button up. We took polyester blend jersey-fabric (found in most standard cycling jerseys) and fashioned into a retro Hawaiian shirt. It was even cut to ensure that jersey ride-up on the back and sleeves would be minimal.

We made the Button up because we don’t like wearing highly technical gear. We like wearing fun, functional apparel on-and-off the bike and the combo of style & material makes the HANDUP Button up ready for anything.
