The Asics Men's Storm Shelter Jacket utilizes our ultra lightweight Storm Shelter fabric (obviously) to protect you from wind and rain without needless bulk. So, when the weather stops at never to keep you indoors, just slap on our Asics Men's Storm Shelter Jacket and tell it to kick rocks-because you've got work to do. It's fully seam-sealed, leaving zero room for H2O to sneak past its defenses, and the protective wind panel does the same for unwanted airflow. Speaking of airflow: if you need to breathe a little easier, just unzip the back and underarm vents and let off some steam. Kind of like a sunroof…but for a jacket…whatever. Trust us, you'll be glad you have the option. You'll also be glad you have tons of storage pockets and a cord lock hem system for a secure fit during every step. Weather-shmeather. Get out there and RUN.
