The Curvations line of pet carriers from Petmate combines style with some innovative features. The Curvations Kennel and Carrier(shown above) has openings on all sides for ventilation and visibility and the soft yet rigid material is easy to clean. It opens from the front or the top for easy access and the whole thing folds flat for convenient storage.
For traveling with smaller pets, the Curvations Underseat Carrier was designed specifically to fit under an airplane seat. Made from the same soft material, it also folds flat when not in use.
And finally, for fashionable pets on the go, the Curvations Tote is designed to rest easily on your hip and features an adjustable padded strap, as well as the convenient stowaway design.
All three are available from Amazon.
