A zippered warm-up for frosty Tuolumne bouldering. This sleek zip-up has a smooth poly/spandex exterior (Polartec Power Stretch) that resists abrasion yet stretches for acrobatics. It also defies snagging and cuts wind. Inside, a soft layer of Capilene Expedition Weight Stretch fleece adds warmth for belaying and disperses moisture once the sun rises. Regulator R1 fleece panels, sewn over the arms and inside the collar, are easy on the skin. Details: offset shoulder seams and two mesh-lined hand pockets. Imported.
