The Hawaiian shirt of the '90s just got a major upgrade-the Trail Sender Short Sleeve is durable enough to withstand low-hanging branches or quick shimmies up steep rocky approaches, with enough style to earn a permanent spot in your daily rotation. Made with lightweight polyester fabric with high-rated UPF 50, it provides plenty of stretch and sun protection for mid-trail dance breakdowns, so you can be the life of the party, wherever it kicks off.
