The short version
- US life jackets are moving from the old Type I–V labels to performance Levels (50, 70, 100, 150, 275). The number is minimum buoyancy in newtons.
- A Coast Guard rule took effect January 6, 2025, with enforcement from June 4, 2025. Jackets that were legal before still count if they're in good, serviceable condition. You don't need to replace a good Type III.
- Federal law: one approved wearable life jacket per person, sized for that person; a throwable on boats 16 ft and over (canoes and kayaks exempt); children under 13 wearing one while underway, unless state law says otherwise.
- Level 50 jackets and many inflatables only count if you're wearing them. The label tells you.
- A jacket that doesn't fit doesn't work. Do the lift test on every child, every season.
For decades, choosing a life jacket meant learning a Roman numeral code. That system is being retired in favor of a performance-based label shared with Canada. You'll see both label styles on docks for years, so this guide explains both, along with what the law requires and how to make sure a jacket will float the person wearing it.
Why life jackets matter more than any other gear
In its 2024 recreational boating statistics, the US Coast Guard reported 556 boating deaths, the fewest in more than 50 years. About three-quarters of those who died drowned, and 87% of drowning victims were not wearing a life jacket. No other piece of gear changes your odds that much. The best life jacket is the one comfortable enough that you actually keep it on.
What changed: from "Types" to "Levels"
The Coast Guard stopped requiring the Type I–V code on new labels in October 2014. The goal was to make labels clearer, give buyers more choice and align US standards with Canada's, so manufacturers wouldn't have to build US-only products. The final Lifejacket Approval Harmonization rule, published in the Federal Register in December 2024, took effect January 6, 2025, and the Coast Guard began enforcing it June 4, 2025. It folds the newer UL 12402 performance standards into federal approval rules.
The most important line in that rule for everyday boaters: life jackets that met carriage requirements before the rule continue to do so. You don't need to buy new equipment if your current jackets are in good and serviceable condition. A Type III vest from 2019 that fits and isn't damaged is still legal.
The new performance Levels
| Level | Minimum buoyancy | Intended use |
|---|---|---|
| 50 | 50 N (about 11 lb) | Competent swimmers near shore or with help close by, in calm water. Marked "Not recommended for weak or non-swimmers." Must be worn to count. |
| 70 | 70 N (about 15.7 lb) | Most recreational boating and paddling when help is nearby. Low bulk, comfortable to wear all day. This is the level most classic Type III-style vests fall into. |
| 100 | 100 N (about 22.5 lb) | Sheltered and calmer water, not rough water. The new Level 100 lifejacket standard requires turning ability, and you'll see it on commercial vessels. |
| 150 | 150 N (about 33.7 lb) | General use and foul weather. Designed to turn an unconscious wearer into a safe position. |
| 275 | 275 N (about 62 lb) | Extreme offshore conditions. |
Pound figures are converted from newtons (70 N ≈ 15.74 lb, per the Coast Guard). For perspective, the Coast Guard notes that most adults need only about 7–12 lb of buoyancy to keep their head above water. Extra buoyancy buys you a higher float, better face-up stability in waves and room for heavy clothing.
The old Types, for reference
- Type I: Offshore. The most inherent buoyancy, and it turns most unconscious wearers face-up.
- Type II: Near-shore. Turns some unconscious wearers face-up.
- Type III: Flotation aid. Holds a conscious person upright but won't turn an unconscious person. This is the classic paddling and watersports vest.
- Type IV: Throwable: cushions and ring buoys. Not worn.
- Type V: Special use (paddling, sailing harnesses, work vests, some inflatables). Only legal when used as the label describes, and often only when worn.
How to read a new-style label
The new labels use icons as well as text. Here's what to look for:
- The Level number, in a bold box. That's the minimum buoyancy in newtons.
- Turning icon. A curved arrow means the jacket is designed to turn an unconscious wearer face-up. The same icon with a slashed circle means it has no turning ability.
- Water and rescue icons. These show the conditions the jacket is meant for, from calm water close to shore with help nearby to rough water far offshore.
- Activity warnings. A slashed icon over a personal watercraft, towrope handle, towed tube or whitewater boat means the jacket is not approved for that activity. No slash means no restriction.
- Size and fit. The wearer weight (and often chest size) the jacket is designed for. Federal rules require the jacket to be "of an appropriate size and fit for the intended wearer, as marked on the approval label."
- USCG approval number and the testing lab. Your jacket must be legibly marked with its approval number to count.
- Wear requirement. Text such as "must be worn to be counted" tells you it doesn't count toward your required equipment if it's stowed.
What the law actually requires
Federal requirements (33 CFR Part 175) apply on recreational vessels. States can add to them, and many do.
| Requirement | Details |
|---|---|
| Wearable per person | At least one Coast Guard-approved wearable life jacket on board for each person, of an appropriate size and fit. |
| Readily accessible | Wearables must be readily accessible: not in sealed plastic bags, locked compartments or buried under gear. |
| Throwable | Boats 16 ft and longer must also carry one throwable device, and it must be immediately available. Canoes and kayaks of any length are exempt from this throwable requirement. |
| Children under 13 | Must wear an approved life jacket while the vessel is underway, unless they're below deck or in an enclosed cabin. If your state has its own child-wear age, the state rule applies. |
| Serviceable condition | No large tears, no hardened or waterlogged foam, no missing foam. Inflatables must have a properly armed inflator with a full cartridge, chambers that hold air and working status indicators. |
Kayaks and canoes are vessels. The Coast Guard also treats stand-up paddleboards as vessels when they're used outside a designated swimming, surfing or bathing area. That means the life-jacket rules apply to paddlers too.
Inflatable life jackets are not for children, weak swimmers or non-swimmers. The UL standard behind current approvals requires adult-supervision warnings for wearers under 16, and most inflatables are labeled for ages 16 and up. Many are also not approved for personal watercraft or towed sports, because a hard fall can damage them or set them off. Check the activity icons before you buy.
Foam, inflatable or hybrid?
| Style | Pros | Cons | Best for |
|---|---|---|---|
| Inherently buoyant (foam) | Floats with no action needed, low maintenance, works for kids and non-swimmers, takes impacts | Bulkier and warmer | Kids, tow sports, PWC, paddling, anyone who might be knocked unconscious |
| Inflatable (belt pack or yoke) | Very low profile and cool. High buoyancy once inflated. | Must be armed and maintained. Not for kids. Often must be worn to count. A belt pack must be pulled over the head after inflation. | Adult swimmers fishing, cruising or sailing; SUP touring where approved |
| Hybrid | Some foam flotation built in, with inflation for more | Less common, and pricier | Adults who want a backup plan |
The Coast Guard's own reference numbers show the gap: a typical adult foam Type III provides 15.5 lb of buoyancy, while an adult inflatable Type III provides 22.5 lb once inflated, but zero before it inflates.

Sizing and fit: the part that actually saves lives
Coast Guard size categories for children and adults are based on the wearer's weight:
| Category | Wearer weight | Look for |
|---|---|---|
| Infant | 33 lb or less | Head-support collar, grab handle, crotch strap |
| Child | Over 33 to 55 lb | Crotch strap, head support, bright color |
| Youth | Over 55 to 88 lb | Adjustable side straps, a snug cut |
| Adult | Over 88 lb | Chest-size range that matches you |
New-style labels may list weight and chest ranges directly rather than these categories. Go by what's printed on the specific jacket. Adult jackets are sized by chest measurement, not weight, so measure around the fullest part of your chest.
The 60-second fit check
- Buckle and zip everything, then tighten the side and shoulder straps from the bottom up.
- Do the lift test. Have someone grab the shoulders of the jacket and pull up. If it slides up past the chin or ears, it's too big or too loose. For kids, this is the single most important check.
- Range of motion. Paddle, cast or reach overhead. A jacket that chafes ends up off and under a seat.
- Test it in the water. Every season, in shallow water, relax and float. You should be able to keep your mouth clear easily. Kids should practice this too, so their first float isn't an emergency.
Buy kids' jackets for the child they are now, not the one they'll be next summer. A "room to grow" jacket fails the lift test, and kids slip out of them. Recheck fit at the start of every season.
Care and inspection
- Foam: The Coast Guard recommends testing foam jackets in the water at least once a year. Throw away any with tears, hardened or waterlogged foam, or broken hardware.
- Inflatables: Before each outing, check that the cartridge is full and the status indicators are green. If they aren't, the jacket isn't serviceable and doesn't count. Re-arm after any inflation, and follow the manufacturer's schedule for oral-inflation leak checks.
- Storage: Rinse in fresh water, air dry out of direct sun, and store somewhere ventilated. Don't store them compressed under heavy gear. Our winter storage guide has more.
Choosing by activity
- SUP and kayak: Level 70 foam paddling vests with large armholes, or an approved inflatable belt pack for adult SUP touring. Kids always wear foam.
- Tow sports and PWC: Foam vests with no PWC or towing restriction icon. Many riders prefer a snug neoprene-shell vest. See tow sports safety.
- Fishing and cruising: An inflatable suspender-style jacket is comfortable enough to wear all day.
- Cold water: A life jacket keeps you afloat through cold shock, but it doesn't keep you warm. Read Cold Water Shock and the 1-10-1 Rule.
FAQ
Is my old Type III life jacket still legal?
Yes. The Coast Guard's 2025 harmonization rule states that life jackets that met carriage requirements before the rule continue to do so, provided they're in good and serviceable condition and fit the wearer.
Does a Level 50 vest count as my required life jacket?
Only while you're wearing it. Level 50 devices must be worn to count toward required equipment, and they're marked as not recommended for weak or non-swimmers.
Do I need a throwable on my kayak or paddleboard?
No. The federal throwable requirement applies to boats 16 ft and longer, and canoes and kayaks are specifically exempt. You still need a wearable life jacket per person when you're outside a swimming, surfing or bathing area. A rescue throw bag is a smart extra for groups.
At what age can kids stop wearing a life jacket on a boat?
Federal law requires children under 13 to wear one while the boat is underway, unless they're below deck or in an enclosed cabin. Some states set different ages or add rules for PWCs and towing. Check your state boating agency.
Can I use an inflatable life jacket for wakeboarding or on a jet ski?
Usually not. Many inflatables carry activity icons or label text that exclude personal watercraft and towed sports, and a hard fall can damage or set off the inflator. Use a foam vest whose label shows no restriction for that activity.
