The Swamp Cooler Zip Vest provides superior sun protection and acts as a natural cooling agent during hotter days out. Made using a lightweight 3-layer construction that cools the core, this vest combines a stretchy, wicking outer layer with a highly breathable mesh lining for enhanced ventilation and maximum comfort for your canine in hot climates. Ideal for sunny days out, the back spandex is finished with UPF 50+ rating for additional sun protection. Oversized armholes allow for an extensive range of motion whilst the zippered closure keeps the cooling effect close to the body and ensures a snug fit.
