How do you choose a base layer?
Perfect question for changing seasons.
Part of it has to do with your body temp (do you run hot, or cold?). Another part has to do with what you'll be doing (lots of start/stops or hardcore burning?).
But there's also a little science to it. Choosing the right material will help regulate your temp no matter what you're doing.
Here's a simple explanation about how to choose between our LITE base layers and our 200s.
