Want the vest, so that our fishing trips are a little more secure with our son. So he will also wear a T-shirt underneath. The vest is available in S (15-20 kilo) and M (I think 20-30 kilos). Size S is designed to fit 2-3 year olds. My shoot is not even 2 and the zipper is at least 5 cm wide apart -. And my son is not thick with 14 Kilo. Too Bad. Send the S back now and try the M. Maybe adjusts.
