Made from dual-brushed fleece, the Rockmoon feels super soft and comfortable, even when worn over a short-sleeved shirt. In addition to the standard size chart, this fleece also includes the actual jacket measurements in the extra image. You can compare them with the measurements of your favorite shirt to find the right size. The full-length zipper gives it a jacket-like look. You can wear the Rockmoon as your outer layer when you dont need wind protection but a short-sleeve isnt warm enough. It also works perfectly under a winter or shell jacket as part of a layered clothing system. - Regular fit - Full-length zipper - Protective collar - Two zippered hand pockets - Elastic edging at hem and cuffs - Active Dry Warm fleece made from recycled polyester fibers and elastane - Halti THINK Ahead product: contains recycled material, does not contain PFC compounds
