Shed a Layer - If you are comfortable when standing still, you will overheat quickly once you start climbing.\r\nKeep Cool - If possible, avoid sweating. Once your layers get wet it is difficult to dry them out during a day of activity.\r\nRegulate Your Temperature - Climbing efficiently is directly related to how hot or cold your body is running. Taking the time to shed or add a layer will improve your climb.\r\nLayer Up at Rest Breaks - Quickly throw on a jacket or your parka at a break to trap the heat you generated climbing. \r\nCaring for Your Insulation Layers There are several down and synthetic cleaning products that are perfect for your insulation layers, including McNett Gear Aid ReviveX® Down Cleaner and Synthetic Fabric Cleaner. Make sure to follow each garment\'s care instructions. Front-loading washers work best. When drying, use low heat. For drying down add tennis balls in order to break up the clumps of wet down so that their loft, therefore warmth, can be restored. Avoid dryer sheets or fabric softeners, as they will affect the water resistance and breathability of the garment.
