How to properly fit a life jacket

When a life jacket is too big or too small, you won’t just feel uncomfortable or look goofy. This critical piece of equipment could fail to do its job, which is saving you if you fall off your boat, SUP, kayak or even the dock at your favorite lake.

Finding "the one"

A life jacket should feel like a hug from a great date or your best mate. And just like that special person in your life, it has to be a good fit!

You might find life jackets provided on a rented boat or with your new kayak or stand-up Paddleboard (SUP).

But just because a life jacket came with your rental or purchase doesn’t mean it’s a good match. If the one you have doesn’t fit right, it’s not the right one for you. Don't hesitate to borrow from our life jacket loaner stands or find one that's a better fit.

Your life jacket should feel like an extension of you.

Testing the waters

So, how do you find your nautical soulmate? Trust us, it’s easier than deciding if your should swipe right. Just follow these four steps:

1. Check compatibility:

Look inside the jacket to see if the life jacket is USCG approved.

Make sure the life jacket is rated for your current weight and planned use.

2. See if you feel secure:

You don’t need a person in finance (“trust fund, 6’5”, blue eyes”), but you have to make sure the life jacket is secure — that means trying it on.

Wear what you’ll wear on the water.

Zip and secure all snaps and buckles.

3. Lock it in:

The fit needs to be like a warm hug that still lets you breathe easy and have full range of motion.

Start with the bottom waist strap and secure it first.

Work your way upward, adjusting the straps to be snug as you go.

4. Time to meet your friends

Now, can your life jacket pass the final test: What do your buddies think? Is it the right fit?

Raise both arms straight overhead.

Ask a trusted friend or family member – or the person at the marina if that doesn’t feel weird – to grasp the top of the PFD at your shoulders and gently pull upward.

If the jacket rides up over your chin, ears, or face, it's too big! Go back to Step 1, with a smaller size.

Life jackets for the whole family

We don't usually move this fast, but it's time to talk about kids.

It's important to understand adult life jackets are not safe for children.

Children require child-size life jackets for their weight and size (and remember, kids under 12 are legally required to wear them on the water).

Kids' life jackets may include a crotch or leg strap. This prevents the jacket from slipping over their head in the water. Make sure this strap is fastened and adjusted properly for security, and follow any other manufacturer’s instructions to ensure the child is properly fitted.

“On the body, not the boat”

We hear safety experts use that quote often, and for good reason: A life jacket does no good if it's on the boat or kayak!

In 2024, the U.S. Coast Guard reported 87% of drowning victims in recreational boating and paddling accidents were not wearing life jackets. That statistic has hovered around 85% for the last several years. Many of these tragedies could have been prevented just by wearing a life jacket.

So, we’ll keep sharing the message: Your life jacket should be on your body.

And, if you’ve found the right fit, it shouldn’t cramp your style or movement. You’ll feel more secure on the water than you would have without it. And, unlike some dates or best mates, if you wear your life jacket, it won’t leave you on read should the unexpected occur.
