Arm holes are very small,
Verified Purchase(What is this?)
This review is from: Zoggs Kids Float Discs Learn to Swim Arm Band - Yellow, 2-6 Years (Sports)
Arm holes are very small and I returned for a refund without opening the packaging as I knew my 4-year-old's arms would not fit through. Zoggs make a larger version of this for age 6-11 but I haven't managed to find online.
