Patagonia's fine merino wool can be found in a variety of shapes and sizes, and this spring you'll want the Patagonia Merino Daily Polo Shirt in your wardrobe, either to layer under a soft shell for street style or toss on for all those business-casual brunches you'll be attending. True to Patagonia's environmental leadership, the Merino Daily Polo Shirt is made with chlorine-free merino wool - protecting our water supply - and recycled polyester to reduce waste.
