"What Our Gearhead® Experts Are Saying: ""This polo is unbelievably comfortable for a collared shirt. The TreeBlend fabric feels more like a tee than a traditional polo, with plenty of stretch and breathability. It’s my go-to when I need something a bit more polished but still want all-day comfort."" We wear the Astir Polo Shirt when we want a step up from a t-shirt without giving up comfort. Built by Tentree with their ultra-soft TreeBlend fabric, this polo feels smooth, breathable, and flexible enough to wear all day, whether we’re traveling, heading into town, or spending time outside. The classic collar and button placket keep the look clean and versatile, while the sustainable blend of organic cotton, recycled polyester, and TENCEL™ Lyocell delivers a soft handfeel with stretch that moves naturally. It’s the kind of shirt that easily earns a spot in both casual and everyday rotations."
