I personally use these as technical undershirts for everyday wear, in the colder months. When it's cold and/or wet, it's great to have the layer closest to your skin wick away sweat and dry fast. Unlike a cotton t-shirt, polyester doesn't absorb and hold the moisture close to your skin, so you aren't getting chilled by evaporative cooling like you normally would. Instead, your sweat is wicked and spread out on the fabric, so that it is evaporating quicker away from your skin instead of being absorbed by the fabric and held right against your skin. These shirts also don't feel cold to the touch like cotton does either.Although these aren't the most fashionable shirts on their own, they work great as a cooler weather undershirt beneath a midlayer like a flannel shirt, sweater, or fleece. They have effectively replaced normal cotton t-shirts for me when it starts to get cooler, and since they are so affordable, I have enough to wear each day of the week if needed. A great value for layering!
