Flylow envisioned the MacReady as an everyday short, designed to take a beating over a long lifespan. Its mostly cotton but has a trace of spandex for stretch. (Because you never know when youre going to need to climb a tree, leap over a river, or make a dash for an airplane.) The fabric uses a brawny oxford weave for long-lasting durability, and the MacReady fashioned side gussets for ample mobility when youre on the go. You could hike or climb in this do-it-all short, but mainly youll just live in it.
