I LOVE this bjorn. We had the original and when our son was 20lbs I couldn't carry him in it anymore but he was not done being carried! I can wear him for hours and it doesn't hurt. Plus he loves it. The Bret is great because you can see dirt and clean it easily, with the black we could never see any of the dirt but now we see how much is really there. Plus the mesh is much cooler. I will say my husband doesn't like it as much as the original, but I like it much more!
