Your Pack

Layering is at the heart of this category. The best way to prepare for any outdoor activity is to wear a performance base layer for wicking away perspiration, a middle, insulating layer to trap your body heat, and an outer shell to keep the elements at bay, whether it is wind and/or water. Socks are also an extremely important, yet often overlooked and under-appreciated, part of an intelligent outfit.
