Thank you for viewing. This product uses mid-weight Geoline®, which quickly absorbs and disperses sweat to keep your skin dry. The box structure, with a smooth outer layer and a soft inner layer connected by partitions, retains dead air (non-moving air as an insulation layer), ensuring high heat retention. It can be worn widely, from activities in cold seasons to everyday use. It is a mid-weight fabric. - Brand: mont-bell - Color: Black - Style: 1107720 - Material: 86% Polyester, 14% Elastic - Size: Kids 135
