How to choose the Right Size Life Jacket

Our life jacket size chart is up to date with all manufactures sizes based on chest size, and includes all brands that we sell for 2017. If you are on an iPhone and want to skip the article, please click here to: Jump to the Size Charts

MOST IMPORTANT: If you can put more than 3 finger widths in the gap between your shoulders and the shoulder area of the life vest, your life vest is too big. That vest will not keep your head above water:

NEVER have a huge gap in the shoulders.

The law says that you must have Coast Guard Approved life jackets in the boat for all passengers, even for the strong swimmers. Unfortunately, there is no law that says life jackets must be the correct size. That is your responsibility. Please click on the icon to view a safety video about life vest size and shoulder gap:

The coast guard estimates that more than half of all boaters have life jackets that are way too big or the wrong type. A father hands out adult life vests to his kids, because that is all he has. He should have purchased types of life vests designed for children, youth, or teens. Wearing a life jacket that is way too big or that has a huge shoulder gap is like not wearing a life jacket at all and it will not keep you safe..

Neoprene, as shown in the picture of the girl, should fit snug when dry. The size is OK if you stretch the vest 2" to 3" to zip it up. If your neoprene life vest is too easy to zip up dry, that vest is too big. When Neoprene gets wet, it stretches. That is why it needs to be tight when dry. It will feel more comfortable in the water.

Nylon, as shown by the Connelly nylon vest below, should meet at the buckles and not overlap. If it overlaps, it is too big.

Another factor to consider is type of activity in the water. All manufactures size charts assume you will be using the life vest for action water sports, and sizes are specified for that type of snug fit. Legally, we are NOT allowed to modify those charts even if a customer complains that his life vest fits too tight. If you are fishing or cruising around in a boat, canoe, paddleboard, or other leisurely water activity, your life jacket does not have to be as tight as the life jackets used for action sports such as wakeboarding or waterskiing. Remember to comply with the shoulder gap test. Even leisure life jackets for Fishing or boating should not have a huge gap in the shoulders.

The newer Hybrid neoprene life jackets use a combination of materials including closed cell marine foam and neoprene. These advanced life jackets are made by Oneill, Connelly, Hyperlite, and HO Sports. These life jackets have Biolite, Hydrozote, or other proprietary neoprene materials that are lighter and dryer than traditional neoprene, and will NOT feel soggy or heavy when you are riding a waterski, wakeboard, wakeskate, or wakesurfer. Closed cell marine foam is a material that will not get soggy, and some manufacturers went a step further to make it with flexible foam sections or panels using proprietary materials as NytroLite which is even lighter than closed cell marine foam. Some have a flex back for comfort, and some have lumbar support for fatigue. They are designed to be light weight, comfortable, provide freedom of movement, yet retain Coast Guard Compliance. These newer life jackets do not stretch as much when wet, so they don't have to be as tight when dry. These newer life jackets should still fit a little snug. The picture below is an example of such a life jacket.

Neoprene, Hybrid, Biolite Neoprene, and HydroZote Life Vests

Fit warning on newer advanced life vests: The newer advanced neoprene life jackets are not as stretchy as the lower priced regular neoprene life jackets so they are NOT very forgiving on size. Advanced life vests for wakeboarding and waterskiing are designed to fit very snug and the size charts run tight. They are designed for safety assuming that you are going to get towed behind a boat at high speeds. If you are a big man or woman trying to stretch into a 2XL or 3XL life jacket, make sure the vest has a flex panel on the back so it can stretch a little more to make room for your mid section and tummy. Flex Back or no Flex Back, you will absolutely need to go up a size if your tummy is bigger than your chest. If you are using an advanced watersports life jacket for leisure sports such as fishing, paddle boarding, canoe, or other leisure, buy a size bigger for comfort.

Flex Back Life Jackets are Size Forgiving

Flex Back life jackets fit better and feel more comfortable than the neoprene life vests without a flex back. Flex Back vests have a much wider tolerance on size, so it is less likely to make a the mistake of buying a life jacket that is too small. The Flex Back feature is found on many 2017 Life Jackets by Connelly, Oneill, HO Sports, and Hyperlite. This feature is also called V-Back, Flex Fit, True Fit, and U-Back. Below is a an example of flex back. Click on the picture below to go to that vest:

Oversized: For big overweight guys and gals who do not fit into a standard XX or 3X size, you can buy an oversized life vest up to size 7XL. Our largest Neoprene life vest is up to size 4XL and 4XL-TALL. Our largest Nylon is up to 7XL.  We are the only dealer selling the HO Sports Tall nylon life vest, and the first to carry the Hyperlite Indy TALL Oversized Neoprene Life Jacket. (See the Footnote * about to measure chest and tummy for the largest life vests).
Oversized Life Vests

How much weight will a life jacket hold up in the water?

If I weigh 400 lbs, will a life jacket float my weight? How much weight will a life jacket support? Fact: Coast Guard Approved Life jackets are rated by chest size, not by weight. a USCGA Approved life vest will safely float your weight if the life jacket fits you. Remember our bodies have at least 15% fat and fat is lighter than water. The boyancy in a USCGA life jacket is more than enough to support your weight in the water.

What is the difference between a regular oversized and TALL oversized life jacket?

Water Ski World is the only USA dealer selling the new HO Sports 5XL-TALL nylon life vest for big and tall men and the first to sell the Hyperlite Indy TALL neoprene life jacket. (Women buy these too). The TALL life jackets are 3 inches longer than standard life jackets for those tall men who want a little more coverage on the tummy. The biggest complaint about most oversized life jackets today is that they are too short and dont cover a bulging gut. Most men wear a t-shirt underneath to protect from the sunburn and cover the belly, but some fashion minded plus sized women complain that a lot of life vests look more like a bra than a life jacket. The cosmetic problem is solved with the TALL life vest. The person modeling the HO Sports vest below is 6 ft 8 in tall and weighs 280 lbs. He is big and tall wearing the HO Sports size 2XL. The first picture shows a regular oversized HO Infinite Life Jacket size 2XL. The second picture shows the 2XL-TALL version of that same vest and standing next to the big oversized Connelly Big Daddy Ski. Note how the bulge in the belly is covered better on the TALL vest.

HO Sports Regular Life Jacket vs TALL life jacket

Below is a customer 6' 7" Tall at 350 lbs wearing the Hyperlite 4XL-TALL NEOPRENE Life Jacket. Neoprene has more stretch than nylon so it fits perfectly on this 350 lb man.

All life oversized life vests we sell, regular or TALL, are US Coast Guard Approved and have compliant flotation for your size. All measurements are based on chest size. (See the Footnote * about to measure chest and tummy for the largest life vests).

(Competition vests are not on our size charts because buyers are watersport experts who already know the correct size to buy. Comp vests are not USCGA approved.)

*Footnote for Oversized vests: Measure your chest circumference under the arms and across the pecs. Also measure the belly. If your belly measurement is bigger than your chest measurement, the guide based on chest size may not be right. In that case, it is better to buy a size larger than what is indicated by your measured chest size.

Manufactures size charts based on a chest size is not a guarantee by waterskiworld that your vest will fit because people have different body shapes. Buyer is responsible for return shipping to exchange for different size if the vest does not fit.
