Question: Is this vest good for snorkeling?  I'm trying to find vest that's not too restrictive for movement yet safe for snorkeling. Thanks.
Document: Child grew out of our previous set of 3 identical vests, and since not yet a full swimmer, this vest provides very nice supplemental support. 4 stars since the wraparound tether underneath is way too short to fit our tall child. But head is kept fully above water if floating without touching bottom, and that's what we wanted. So as an aid it works and fits well, and is overall softer and more comfortable than our previous vests.
Size confusion aside, this is an awesome vest for kids who don't know how to swim yet.
Bought it for my grandson but the only problem is the strap it goes up his crotch and hurts maybe something without a strap or a different design but the vest is very safe
I bought this vest for my oldest grandson and we were very pleased how easy it was to put on him. The vest is not bulky and he has lots of free movement. Highly recommended.
This vest might be good for a child who already knows how to swim, but may need a bit of extra assistance. My toddler weighs 35lbs and if I don't hold him while he's wearing it, he goes totally under the water. This vest will not make a child float.
The vest material is of high quality, it's lite weight (1lb) sturdy and well constructed. The designer truly had a Urban kid in mind with the black and lite green stripe against the blue body of the vest. It gave my grandson a swag in his step. Keep up the good job.
This is NOT what I would call a true &#34;neoprene&#34; vest. It is a polyester fabric covering loosely over thick foam, rather than bonded to a thinner layer of black rubber foam. Strictly a thicker life-vest. If you want a true life vest however, this seems like good quality.
The weight range for this product is 30-50 lbs. I have a large 1.5yo and a slim 3.5yo that are in the mid-30 pound range. We purchased these and while they both fit well on my kids, the vest could not keep either of them above water. That is a big problem. Due to a time crunch with a vacation around the corner I'm going to use these with water wings or other floaties. If I had more time, I would definitely return these.
In Canada, a vest that prevents a child or adult from sinking is called a PFD (personal flotation device). If the item isn't a PFD, you don't use it as a life saving aid. We purchased this vest for our 2 year old grand-daughter 2 years ago, another one for our 2 year old grandson last year; it was quite clear to us that it was designed to ASSIST with floating, and I'm pretty sure that this was quite clear on the packaging.
After seeing my friends child in this Speedo's swimming aid, I could only find this product online. It keeps my daughter more afloat than the Fisher Price swimming vest that I used for her. I feel more at ease with her in the pool whilst wearing this.
