This is one of the best things I have ever bought. I bought to take on holiday as I thought it would help with the twins swimming practice as it alowed free movement of all limbs as opposed to arm bands etc.
The twins loved them as they were easy to put on/;take off, totally supportive and didnt move at all once on (no slipping aorund etc)
At the end of the week 1 of the twins took it off and could swim without this. I honestly believe that with the help of this and some guidance of limb movement etc it hugely assisted in him learning to swim in 10 days.
Lightweight, Quick Drying, Supportive
