Obviously, we don't recommend wearing most shirts multiple days without a wash, but the 72-hour merino polo from Proof is made to have your back when you're not able to get to a washer. If you're doing any kind of lengthy multi-day trips, you'll be very happy you chose this polo.
Transcontinental flights, long road trips, low-weight camping trips would all benefit from some merino wool shirts. And while each one of these polos sells for $88, you can grab two for just $140.
