Easy-to-wear and ideal for long hikes, backpacking, and summer trekking, the women’s CANYON LONG SLEEVE T-shirt by Mountain Hardwear is built for the trail. It’s made from low maintenance, wrinkle-free polyester with back vents that help keep you fresh. The fabric is also UPF 30 to protect you from the sun. Roll-up sleeves allow you to air your arms on warmer outings. A zip security pocket at the chest provides storage for your smallest, and potentially most valuable hiking essentials.
