Features
- Large-Capacity Storage
21L main compartment + 1.9L front pocket provides ample space for your pet and essentials, suitable for pets up to 6.5kg. Keeps your small companion safe and comfortable on every ride. - Breathable & Comfortable
Generous mesh panels ensure excellent airflow while blocking direct sunlight, allowing your pet to breathe freely and stay comfortable throughout the journey. The widened and thickened honeycomb back design keeps shoulders and back cool, prevents sweat buildup, and ensures a comfortable ride for both owner and pet. - Ergonomic Shoulder Straps
Cotton-filled, thickened shoulder straps with ergonomic curvature distribute weight evenly, reduce pressure, and stay secure during rides. Even narrow-shouldered users can wear the bag comfortably without slipping. - Foldable & Travel-Friendly
Designed to fold along with your Brompton bike, this bag doesn’t interfere with folding. Easy to carry on subways or elevators without removal, making it highly convenient for urban commuting. Hidden shoulder straps and a quick-convert handle allow it to transform into a backpack or hand-carry bag for commuting, shopping, or strolling.
