I had a friend give me a wrap-carrier that was based on the HAB I believe which DS & I really liked but it was a PITA to tie up when going to shops, getting in & our of car etc. Is the Close Carrier pre-done in the sense that you can put it on and just put bub in? Is that the main difference? I need to go and do some more research. I have a sling but would like an easy to use carrier for #2 as well.
