The weather along the way to the summit will inevitably fluctuate. Be prepared with the lightweight Hanging Rock 1/2 Zip Top in your pack. Flatlock seams reduce irritation and chafing while the UPF-50 rating helps block the sun. Forward-set shoulders and stretch construction make it easy to move, even when layered over another shirt. Thumbholes provide additional protection and keep the sleeves from riding up. A zippered chest pocket keeps the essentials secure and accessible.
