I tried on many of the "good" soft backpack carriers. The Becco, Ergo and Bebo were my top choices. I tried on each one with my 18 month old son and he took to the Boba instantly. He actually liked being on my back in the carrier.
It is so comfortable, easy to adjust and easier to put on. I thought the Becco was a bit short since my son is in the higher percentile for height for is age.
I got the organic Tweet pattern, so cute.
I know that I will be using the Boba for several years and I am seeing the benefits to spending the extra money up front for the soft carrier that is comfortable, easy and stylish. I have heard nothing but complaints about the cheaper carriers---they pinch, too much pressure on the shoulders and neck area. I have hiked with my 25lb son and the Boba is comfortable the entire time.
