My 6 year old boy wears a steamer during summer and we live on the Sunshine Coast. In "winter" he lasts a couple waves at best, so I was contemplating a new wettie to see if it would give him a couple extra waves. Thankfully I thought I'd give the long-sleeve radiator a go before dropping some serious coin. An absolute game changer that allows him to get a few extra waves, concentrate on his surfing and have fun. Highly recommended!
