A budget general purpose youth PFD for roughly 50 to 90 pound kids, with a chest strap and a leg strap to reduce ride up.

Here's the deal:

We tested it head to head against the other top life jackets, and below we break down how it did on Value for Money, Comfort, Mobility, Durability, Versatility, Ease of Use, where it falls short, and whether it is worth your money.

Our Verdict: Onyx General Purpose Youth Life Jacket

An affordable USCG youth vest with a leg strap that keeps kids compliant on a boat, but the real fit range is narrower than the label and it can ride up.

A budget general purpose youth PFD for roughly 50 to 90 pound kids, with a chest strap and a leg strap to reduce ride up.

What's the bottom line?

Low cost USCG Type III option for growing kids.

Nylon shell over foam with an included leg strap.

It ticks the USCG box and the leg strap really does cut down the ride up if you actually clip it. Watch the sizing though, my kid was inside the 50 to 90 band on paper but the fit was snugger than the label suggested, and kids in vests still need constant eyes on them.

Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.

Cheap enough to keep a spare for visiting kids.

Comfort

Plain foam is stiffer than a tailored paddling youth vest.

Open sided cut and adjustable straps help dial the fit.

You might be wondering:

Fine for sitting in a boat, less so for active hours in the water.

Some parents find the foam bulky on smaller kids.

Mobility

Large armholes give kids room to move their arms.

Open sided design allows a swim and paddle motion.

Bulk limits it compared with a fitted youth paddling vest.

Good enough for general boating rather than serious paddling.

Durability

Nylon and foam hold up to normal seasonal use.

Basic buckles, adequate but not heavy duty.

Foam ages faster if left wet or baked in a hot locker, so inspect it.

Reasonable lifespan with care.

Versatility

General boating and recreation, not tuned to a sport.

No pockets or fishing features.

Covers a wide labeled weight band, though the real fit is narrower.

Type III, for conscious young swimmers with adult supervision close.

Ease of Use

Front buckles, chest strap, and a leg strap secure it.

The leg strap must be used to cut ride up, and parents should check it.

Bright colour aids visibility on the water.

Nothing to service beyond rinse and dry.

What Other Life Jackets Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The Onyx General Purpose Child Life Jacket is our best swimming life jacket for kids. A cheap USCG child vest with a leg strap for 30 to 50 pound kids, fine for supervised calm water, but plain foam and it can ride up if the straps are loose.

The Stearns Infant Life Jacket With Head Support is our best coast guard approved life jacket for toddlers. A USCG infant vest with a head pillow and grab handle for babies under 30 pounds, but it is a supervision aid, not a substitute for a hand on your child.

The Stearns Adult Classic Series Life Vest is our best mid-range life jacket for adults. The cheap, dependable spare vest for casual boating, though it runs small for tall or larger adults and gives up comfort and mobility to hit the price.
