Give your around-town days the same level of performance you expect up mountain with the Meeker Short-Sleeve Shirt. This shirt is bluesign-approved, helping to reduce environmental impact and create positive change in Honduras through cool, eco-friendly designs through our Marmot x Thread partnership with Thread International. Postconsumer plastic bottles are recycled into Marmot UpCycle quick-drying polyester fabric and then blended with cotton. Drying quickly and blocking the sun with its UPF-30 rating, this button-down will keep you cool and comfortable, whatever the day brings. It's also garment washed for an extra-soft handfeel. A contrast interior collar, straight hem, and patch pocket add style points.
