My snoozer roll around turns into to a back pack. You can take the wheels off and it becomes a back pack, car seat or a pet bed. My two 4lb yorkies fit in it comfortably.
You can view it at snoozerpetproducts.com. type in the search snoozer roll around and then click on view the detail. It zips close with plenty of venting. It is alo airline approved. I hope this helps.
