I bought this for my daughter. She is 5 and 45 lbs. Theonly con was she wanted a buckle in the front where the loops meet. It's more of a piece of mind buckle because she s snug and safe without an extra buckle. She learned on a rental that had the front buckle. Anyway, it took a few times but now she likes it. It seems like the best buit harness for kids. No padding under the legs is a con too.
This harness was bought for my 5 yr old daughters.
They did not complain of any discomfort after 2 hrs of indoor climbing.
Easy harness to put on squirmmy kids. Easy to attach to protection.
