My son and family had moved out to Australia. We wanted to go and see them and were told we needed rash vests - never heard of them but got lots of friendly, helpful and supportive advice from the guy in the shop. Able to try them on to find right size. Really good experience and have used them swimming and snorkeling. Have seen some amazing g, colourful fish. I really would recommend Worthing Watersports for any water requirements, even for old dudes like us. Excellent! Peter and Lesley.
