You could prepare for cooler weather by stuffing your face with epic amounts of seasonal treats and rich foods — or you could go a healthier, more stylish route by donning the Monterey button-up by Billabong. This long sleeve shirt has a lightweight cotton construction and features a military-inspired Billabong logo pin on the pocket, a woven brand label at the back yoke and a contrast color button-in hood for windy days. Basically, it's comfortable, functional and pretty darn dashing.
