It fits my 40# 3 year old son fine.

My son felt safe and relaxed with the best on, in our hour long boat trip in Lake Atitlan

Fits my 5yr son perfect but wish it had a little more room on

Worked out great for out son

My son wears it for extended periods of time and has not complaints.

It scared me so bad that in the 5 seconds I gave my attention to my daughter, my son's face was being held under the water due to the life jacket

Fits my big son great

my son loves swimming in the pool with this jacket on

Way too small, the neck area chokes my son when he swims

After my child used it one time I felt as if my son was already safer.

This vest fit my 3 year old son well.

Durable but irritated my sons neck

my 4 year old son was very comfortable wearing it, never complained about it.

My son loves it (which is good cause when we are at the lake it is a requirement anytime the kids are near the water even by shore to where it) only problem now is keeping him out of the water lol

Son prefers this over his puddle jumper and actually keeps his head above water

My son isn't impressed with the color but as long as it does the job it should be fine.

My son loves to swim in this jacket

Great product my son was very comfortable

Despite it being snug to my 8 year old son, it's enough to give me a peace of mind that my son is safe in the pool with it.

My four year old son wore this and it worked great, he's tall and thin, 40" and 45 lbs.

My son loves it

Grand son loves it.
