I'd suggest a Close carrier, even though it has ties, because they are already tied for you basically, you just put it over your shoulders and adjust it to your size. Easy as!! I've found it was only good up to about 10kg though because they started to pull too much on the material because its not a real firm type of material - ITMS? Oh, and I think you can wear bubs facing outwards, but its not recommended to have bubs in that position anyway. So thats about the only suggestion I have for an easy to get on and off sling.
