This towel poncho is our favorite! Makes changing at the pool so easy. This is the grey one that looks blue online. He’s wearing size 2T-3T. I linked. Few other and cheaper options too Just put it on, take off swim trunks underneath and put on some dry shorts. No need to go to the car or bathroom to change out of the wet bathing suits before getting in the car. For girls, just take their bathing suit straps off their shoulders before putting this on and you can change in public. LTKkids LTKbaby
