This is my conversion, a lovely Opitai full buckle made with a beautifully soft Didymos Iris 17" wide, and still fits my tiddly little boy at two and a half, but I don't use it much because I always go for my half buckle. Full Opitai rainbow waist, padded straps, headrest, straight (rather than curved) straps so ideal for front or back carries.
Opitai's photos: https://www.facebook.com/media/set/?...2620978&type=3 . Can get some of my own, including action shots, if you are interested.
I haven't washed this, but it is clean and in good condition.
£150 inc SD postage, or would trade for a 4.5m Vatanai Orkney wrap plus a bit of pp, or I *might* consider a trade for a large HB, but it would have to be special.
(I've also listed it on NM, but will do it a bit cheaper for one of you xx)
