Here's a versatile button-up for those warm summer months when you want to look classy, but not like you're trying too hard. The Patagonia Puckerware Short-Sleeve Button Down Shirt has a loose, crinkled weave that'll stay comfortable and forgo the tacky appearance of many collared short-sleeves. It's also constructed with a moisture-wicking blend of recycled polyester and organic cotton that stays true to Patagonia's commitment to environmental responsibility.
