Smartwool Men's Tshirt Style: Sport 150 Park Vibes Graphic TeeColor: Alpine Blue (Bright blue), Blue (it's a nickle blue), Black (It's darker than my photo shows), Dark Blue, Green (It's a bluish green), Grey (It's a purple-ish grey)Sizes available: Small, Medium, Large, XL, XXL (See measurements below)Fabric: 56% merino wool, 44% polyesterGraphic: That Outside LifeWeight: 150 Note: This is the sport t-shirt so it's less merino wool. I've absolutely been abusing mine trail running and hiking and while I usually only go for the merino shirts with 87% merino wool or higher, I must admit this shirt is so far more durable AND I think they spun the merino around the polyester so it really does still feel like a merino wool shirt. It really passes the field test. Regular FitFabric combines the moisture management, temperature regulation, and odor resistance of Merino with the durability and quick dry time of polyesterFlatlock seam construction designed to minimize chafingOffset shoulder and side seams designed to increase comfort and minimize chafing while wearing a backpackUPF 20+ Measurements: SmallChest: 20.5"Length: 27" MediumChest: 21"Length: 22.5" LargeChest: 23"Length: 28.5" XLChest: 23"Length: 30" XXLChest: 24.5"Length: 30" New with tags.
