The key to dressing for the outdoors in cool or cold weather is wearing a base layer that╒s warm and wicks sweat away from your body. The best base layers are made of either wool or synthetic fabrics. Wool is a great choice but can be quite expensive and, unless its fine Merino wool, might be itchy.
For affordability and performance, this Patagonia crew is great. It’s a synthetic polyester shirt that fits like your favorite long-sleeve T-shirt but keeps you cozy even when you’re sweaty because it’s made of Polartec Power Dry.
Also, it has an antimicrobial treatment that prevents odor. Nice bonus! This shirt is one of the most versatile pieces of gear you can have in your closet. You’ll find yourself wearing it for everything from backpacking and campouts to soccer practice and school days.
