The best materials are soft, lightweight, and moisture wicking. TECHWICK is a great example of such a material, and can be used as a skin-tight base layer or a T-shirt. In addition to staying dry, you’ll notice synthetic materials, such as polyester, allow your body to breathe much more, releasing pent-up heat to keep you comfortable. Merino wool is also an excellent material that not only wicks moisture away but also drives away any odors. This makes a perfect base layer in colder weather, but can also be a good choice for any warm-weather hikes.
