Learn how to use a safety buoy for open water swimming, from choosing the right model to wearing and inflating it correctly, plus open water swim safety tips.
Quick Answer
To use a safety buoy, fasten the belt around your hips, attach the buoy so it trails behind you, and inflate it only when you need extra buoyancy or visibility. Choose a model that matches your activity—Restube Beach for family shoreline days, Restube Swim Buoy Pro for open-water laps and dry-bag storage, or Restube Kids Safety Buoy for supervised young swimmers. Remember that no Restube is a Coast Guard-approved life vest, so it adds peace of mind but does not replace supervision or swimming ability.

Open water swimming is one of the most rewarding ways to spend a morning, but lakes, oceans, and rivers don't come with lane lines or lifeguards on every shore. A safety buoy is the simplest piece of gear that makes you easier to spot, adds flotation when you ask for it, and gives you a place to stash a phone or keys. The trick is knowing how to wear and use one correctly.
This guide walks through the process step by step, from picking the right buoy for your swim to inflating it at the right moment. We'll also flag the mistakes that trip up first-time users—like treating a safety buoy as a life vest or waiting until you're tired to pull the trigger.
Step 1: Match the Buoy to Your Swim
Not every safety buoy is built for the same water or the same swimmer. Restube Beach is designed for everyday adventures by the water, giving you and your family extra peace of mind for shoreline hangs, swim sessions, or splash-filled afternoons. Restube Swim Buoy Pro is aimed at visibility and added buoyancy while you swim, and it doubles as a dry bag for water sports adventures—handy if you're taking a lap around the lake or training for a triathlon. Restube Kids Safety Buoy is the inflatable option for children aged 10 and over, with convenient and quick inflation via a trigger pull.
The mistake to avoid here is buying one buoy for every member of the family and every type of swim. A kids' model has different inflation and fit considerations than an adult open-water buoy, and a beach-focused buoy isn't the same as a swim-training buoy. Match the model to the person and the activity before you get in the water.
- Checkpoint: confirm the buoy is intended for your age group and activity before you buy.
- If you plan to carry a phone or keys, choose a model that also works as a dry bag.
Step 2: Fasten the Belt Around Your Hips
Getting started is simple: fasten the belt around your hips. That's the foundation of the whole system, and it's where most first-timers rush. The belt should sit snugly on your hips—not your waist, not loose enough to slide up while you swim. If it rides up, the buoy will drag awkwardly behind you and you'll spend your swim adjusting instead of breathing.
Put the belt on before you enter the water, with the buoy attachment point at your lower back so the buoy trails behind you. That trailing position keeps the buoy out of your stroke and makes you visible to boats and other swimmers from behind. Once it's on, do a quick reach-and-roll test: can you reach the trigger or inflation point without contorting? If not, adjust before you swim.
- Common mistake: wearing the belt on your waist so it rides up under your ribs mid-swim.
- Checkpoint: the belt stays put when you raise both arms overhead.
Step 3: Attach and Position the Buoy
Attach the buoy to the belt so it sits behind you at hip level. In open water, this trailing position is what makes you visible—a bright buoy bobbing behind a swimmer's feet is far easier for a boat operator or paddler to spot than a head alone. For the Restube Swim Buoy Pro, the same belt-and-trail setup applies, and the buoy doubles as a dry bag, so pack anything you're carrying before you seal and attach it.
Don't clip the buoy to your suit, your goggle strap, or a tow line in front of you. Those placements interfere with your stroke and defeat the visibility purpose. If your buoy has a leash or handle, keep it short enough that the buoy doesn't swing into your kick zone.
- Common mistake: attaching the buoy in front of you, where it tangles with your arms.
- Checkpoint: from the shore, can a friend clearly see the buoy behind you?
Step 4: Inflate Only When You Need It
This is the step people get wrong most often. The Restube Kids Safety Buoy inflates with a trigger pull, and it's reusable with CO2 cartridge replacement and a manual inflation option. Adult Restube models follow the same logic: the buoy stays deflated and streamlined while you swim, and you activate it when you want extra buoyancy or a visible float. That means you're not swimming with a balloon dragging behind you for the entire session.
Practice the trigger pull on land first—ideally at the edge of the water with the belt on—so your hand knows where to go without looking. If you're using a model with a manual inflation option, learn that motion too. The goal is to make activation automatic, because the moment you actually want flotation is not the moment to fumble for a valve.
- Common mistake: inflating at the start of the swim and towing a fully inflated buoy the whole way.
- Checkpoint: you can activate inflation by feel, without stopping your stroke.
Step 5: Pair the Buoy With the Right Swim Gear
A safety buoy works best alongside gear that keeps you comfortable and aware in open water. Goggles matter more than most people expect: the BuddySwim Ozean Goggles use patented Honeycomb Cushion Fit technology that naturally conforms to the shape of your face, which helps with comfort on longer swims across a quiet alpine lake or along the coastline. The BuddySwim OzeanX Swim Goggles are made for sunny days and open water, combining comfort with enhanced visibility so you stay focused on the water rather than your gear.
Neither goggle replaces the buoy, and the buoy doesn't replace the goggles—they solve different problems. Goggles keep you oriented and comfortable; the buoy keeps you visible and gives you flotation on demand. Together they cover the two most common sources of open-water anxiety: not seeing well and not being seen.
- Common mistake: swimming open water in pool goggles that fog or leak within minutes.
- Checkpoint: your goggles stay sealed and clear for a full 20-minute swim before you go longer.
Step 6: Know What the Buoy Is Not
This is the safety step that matters most. The RESTUBE is not a Coast Guard-approved life vest—it does not go over your head or wrap around you, and it will not help you in the same way a life vest will. That's true of the Restube Kids Safety Buoy and the rest of the Restube line. A safety buoy adds visibility and optional flotation; it does not keep an unconscious or panicked swimmer face-up.
Treat it as one layer in a layered safety plan. Swim with a buddy or a spotter when you can, stay within your ability, check conditions before you enter, and keep the buoy as a backup rather than a primary rescue device. Kids using the Restube Kids Safety Buoy should always be supervised, and the buoy is intended for children aged 10 and over.
- Common mistake: assuming a safety buoy can substitute for a life vest or for supervision.
- Checkpoint: you can state out loud what your buoy does and does not do before you swim.
Your Open Water Swim Checklist
- Choose the right buoy: Match the model to the swimmer and the activity: Restube Beach for family shoreline days, Restube Swim Buoy Pro for open-water laps and dry-bag storage, Restube Kids Safety Buoy for supervised children aged 10 and over. Checkpoint: the buoy is intended for this person and this type of swim.
- Fasten the belt on your hips: Snug on the hips, not the waist, with the attachment point at your lower back so the buoy trails behind you. Checkpoint: the belt stays put when you raise both arms.
- Attach and position the buoy behind you: Keep the buoy trailing at hip level for visibility; don't clip it to your suit or goggle strap. Checkpoint: a friend on shore can clearly see the buoy behind you.
- Practice the inflation trigger on land: Learn the trigger pull or manual inflation motion before you swim, so activation is automatic when you want flotation. Checkpoint: you can activate it by feel without stopping your stroke.
- Swim with goggles that stay comfortable: Open water demands a reliable seal; the BuddySwim Ozean and OzeanX goggles use Honeycomb Cushion Fit technology to conform to your face. Checkpoint: a full 20-minute test swim with no leaking or fogging.
- Remember what the buoy is not: No Restube is a Coast Guard-approved life vest; it does not go over your head or wrap around you. Swim supervised, within your ability, and with a buddy when possible. Checkpoint: you can state the buoy's limits before you enter the water.

A safety buoy is one of the easiest upgrades you can make to an open water swim—visible, packable, and useful whether you're doing a shoreline splash or a long lake lap. Wear it on your hips, keep it trailing behind you, and save the inflation for when you actually want it. Then treat it as one part of a layered safety plan, not a substitute for supervision or skill.
