I love my caboo! The cotton blend is soft and snug and the rings make it easy to adjust the carrier. The carrier can be worn in 2 ways- 'stretchy wrap' style without having to fold and tie the fabric, making it much quicker to use than traditional stretchies, and ring sling style. Before getting the Caboo I used a closed tail ring sling with plastic rings which was nearly impossible to adjust properly which led me to use my pram more when out and about. Since getting the Caboo the pram has become almost obsolete as it is so much less fuss getting baby into the carrier than hauling the pram out of the car!
