Size reference photo! I just got them today so can't say much about durability yet, but I'd like to add a reference system for sizing. I ordered a pack of small, Aqua Stripe for my 65 lb 9 year old and Green for my 42 lb 6 year old. Both of my daughters are a little below average for their age, but they still have room for improvement. I'll let you know if I have any doubts about the quality, but so far so good!
