I am looking for a harness for my 4.5 yo. Given the age and the fact that she is petite, probably full body would be best. She only climbs occasionally and not very high but still, I would like the harness fit to be as bomb-proof as possible.
I saw a few people here recommending decathlon full body harness and we went into a store to try it on. It seemed quite loose at the back. I could fit the width of my palm quite easily between the harness and her back. Front looked nice and snug.
There is nothing else we can try on locally unfortunately. I would have to order online, then return if it does not fit and I would like to avoid too many returns (one of the stores told me that they have to destroy any climbing equipment returns and I feel bad about it from environmental point of view).
Any recommendations would be much appreciated. TIA
