Very comfortable, fast drying.The strap between legs is removable so I love it . My daughter too.Nice design, light and efficient.I shop Amazon more so these days due to convenience. Great swim vest but I was needing a second one asap and ended up having to go to WM. Cheeper at the WM and did the same job.It states for 50 to 70lbs. My granddaughter is 58 lbs and it won't zip. It is to tight.The back is expandable to fit him.It runs way small I got my 6year old 50lb daughter a large thinking she’ll have a little room in it, not at all she barely fits in it.. it is nice and she likes it but won’t be able to use it all summerNot happy with this item, wouldn't stay zipped up, wrote to company but no reply.. Never used it againMy daughter is 4 and yes, she's a little chubby, but she's super tall. This wouldn't even go on her arms. It also says in the description it's for up to 80lbs but clearly on the product itself, it says up to 60lbs... Don't bother with this. Find the same thing for a little more through speedo and have more peace of mind that it's a quality productNot anywhere near the advertised sizes. Size up if you can. Decent looking otherwise. Can't speak to its performance.
