Last summer we had a swim sweater for my daughter. It was wonderful. After sitting all winter it would no longer inflate. I couldn't find another swim sweater so, I then bought the Swim School Deluxe Tot Trainer with Pants to use for my youngest son. The first one I purchase was deflated by the time we walked from our garage to the pool. I was very dissapointed but figured it was a fluke. I exchanged it for a new one. This time it lasted about a week or three trips to the pool. Needless to say I am very dissapointed in the quality. The concept is great. My son was all over the pool independently and loving it! I replaced the Tot Trainer with a Swim Tee and am hoping for better results!
