I have a peanut sling that both myself and DH can use as we are roughly the same height and size. I havent used it for my baby yet but i have used it in the kangaroo and hip hold for my 4yo nephew and 6 month old friends baby on numerous occassions and found it to be extremely comfy.

It also just folds up and fits into your bag but it does have a padded edge which makes it a little more bulky. Initially i was going to get a bubzilla but couldnt find anywhere in my area who sells them to try one out.

Best of luck, i found there to be so many choices that it got really confusing!
