With the Cloud Chaser, dogs can forge ahead in the spectrum of inclement weather that winter serves up. The jacket’s upper panel is a breathable water- and windproof softshell that stands up to rain, snow, wind, and cold temps. The fleece-lined lower panel holds in core heat and sheds dirt and moisture. Stretch technical fabrics with a zippered closure make for a warm, formfitting sleeved jacket that\'s made to move. With reflective trim and a light loop for The Beacon (sold separately), dogs get a boost in visibility so shorter days don\'t have to mean shorter excursions.
