Koala Button-Up Premium Shirt (Oversized, Lightweight, UPF 50+)
Meet the shirt you’ll reach for every time the forecast turns hot. The Koala Button-Up Premium Shirt is built for peak summer comfort: featherlight, breathable, and moisture-wicking so you stay cool when the sun’s out and the day gets long. Whether you’re heading to the beach, a festival, patio drinks, or traveling somewhere warm, this button-up keeps your look effortless and your body temp in check.
Designed with an easy oversized fit, it drapes cleanly without feeling heavy or restrictive—perfect for layering over a tee or wearing on its own for that relaxed, “I’m on vacation” vibe. And because summer style shouldn’t come at the cost of sun safety, this shirt includes UPF 50+ protection for added coverage during long outdoor days.
