Hiking to the summit, participating in a bike-a-thon, or just roller-blading along in a park, the Active Pak-o-Pet is designed for you to enjoy the outdoors with your pets. New material for outdoor products is gradually introduced for a truly lightweight, comfortable, and durable carrier. For your pet's safety, please do check the outdoor venue's rules and guidelines for bringing a pet along. During warmer months, please ensure none of the ventilation areas are blocked, remember to bring enough water for your pets, and allow them periodic rest periods.
