In reply to markAut:
If it's any use as a short term solution I have an outgrown Black Diamond Wiz Kid harness.
Lodge Jnr has just grown out of it at 13! We've been expecting him to grow out of it for a while but at this age they just seem to get longer and don't get much wider.
In excellent condition, not furry or anything around the belay loop, a bit of ground in chalk as kids always use too much no matter what you tell them.
Open to offers, collection from Huddersfield or happy to post.
