Beginner's Guide to Buying a Buoyancy Aid

Buoyancy Aids, or Personal Flotation Devices (PFD's) as they are often referred to, have come a long way in recent years and they are now light and comfortable to wear, attractive to look at, and do not restrict your movement in the way that many older models used to.
The first thing to understand about a Buoyancy Aid is that it is fundamentally different in design and in purpose to a Life Jacket and to an Impact Vest.
A Life Jacket differs from a Buoyancy Aid in that it is designed primarily to keep you afloat, even if you can't swim, and to rotate you onto your back if you are unconscious so that your head is held above water and you can breathe. For this reason, Life Jackets tend to be bulky and have a pronounced head / neck support plus straps to ensure that the jacket does not come off if the user is thrown into the water at speed. Wearing a Life Jacket for most recreational water sports is impractical (and can be quite uncomfortable), but using them on a boat or for kayaking is perfect, and if you want to tow younger kids in towable inflatables then we also recommend Life Jackets for this purpose too.
An Impact Vest differs from a Buoyancy Aid in that it is designed primarily for protection and freedom of movement rather than buoyancy. They do, however, offer up to 50N of buyancy in some cases. Impact Vests are intended for use during high-speed watersports by intermediate to advanced riders where potential injury could occur from coming into contact with the water (or obstacles / equipment) hard. Impact Vests are tight fitting so that they stay put during a fall and many have no openings so are pulled over the head rather than zipped or buckled up. Impact vests are generally thinner than Buoyancy Aids and often have visible panels for added protection in critical areas of the torso and spine.
A Buoyancy Aid is simply designed to make life easier if you are taking part in a water sport that involves you actually being in the water a fair bit. Buoyancy Aids will assist you greatly, but generally speaking you still need to be able to swim in order to stay afloat. A Good Buoyancy Aid will also provide a certain amount of insulation on cold days and most will provide varying amounts of impact protection depending on their design and the materials used. The accepted standard for a Buoyancy Aid is that is provides 50N of floatation and that it is ISO-approved. Buoyancy Aids are worn like a jacket and fasten at the front or side with either snap buckles or zips (or both). As with most things, you get what you pay for and we recommend that you should always spend as much as you can comfortably afford. The more expensive PFD's are made from higher quality materials, are more comfortable, and have more adjustments / features.
So which is it then?
Most of the time a good Buoyancy Aid will be exactly the right thing to wear. However, as a general rule, younger or less confident people should wear a life jacket as these offer greater security and life-saving capability. If you are a very good wakeboarder or skiier and crash hard and fast then we reccommend that you wear an impact vest. If you wakeboard or kneeboard at cable parks then we also suggest that you wear impact vest regardless of your ability as those obstacles can hurt!.
If you have a boat then for coastal and offshore applications we recommend that everyone wears a life jacket at all times, especially younger passengers and definitely the non-swimmers. Also, think long and hard before you actually allow anyone that can't swim to take part in any form of water sports, even towable tubes, regardless ow the type of vest they are wearing. Anyone taking part in water sports while out on the boat should have a well fitting Buoyancy Aid to change into beforehand, for comfort more than anything else. Having said that, keep younger or less confident kids in a life jacket if they are taking part in watersports. You'll soon get a feel for who needs what and this is why most recreational boat owners keep a selection of life jackets and buoyancy aids in various sizes on board.
Neoprene or Nylon?
The interior of a buoyancy aid will be soft foam and the exterior cover will be either nylon or neoprene. Nylon tends to be cheaper and harder wearing than neoprene and it dries quicker, but neoprene is generally softer and more comfortable and provides better thermal insulation. If you can justify the extra cost then always go for neoprene, but nylon is perfectly good for most applications.
Correct fit is everything when it comes to Buoyancy Aids and spending time in the wrong one will not only spoil your day but it could also be dangerous. To check that you are wearing the correct Buoyancy Aid for your height and weight just perform these simple tests (always perform these checks with the jacket fully fastened).
1 - Is it comfortable? If it is rubbing or is too tight somewhere then it could be a simple matter of relaxing one or more of the adjustment straps. If after doing this you still feel uncomfortable then go for the next size up.
2 - Try taking a few nice deep breaths. If the jacket restricts your breathing at the top of each breath then relax the adjustment straps. If after doing this you still feel uncomfortable then go for the next size up. Remember that some watersports can make you quite out of breath and being able to breathe properly is obviously important.
3. Lift your arms up above your head. If the Buoyancy Aid does not move above the level of your ears then it is the correct size. If the jacket ends up over your head then it could be a simple matter of tightening one or more of the adjustment straps. Start tightening the straps at the waist and work your way up. If the vest has shoulder straps, tighten them last. Repeat the test and if the jacket still ends up over your head then it is too big so go for the next size down.
4. Ask someone pull up on the shoulders. If it moves up past the level of your ears then try tightening the straps. Repeat the test and if it still moves up above your ears then it is too large so go for the next size down.
use your Buoyancy Aid as a cushion. It will damage the foam and
it will lose buoyancy.
Don't leave your Buoyancy Aid lying in direct sunlight for long periods.
Always rinse your Buoyancy Aid in fresh water after use, especially after being in salt water.
Drip-dry your Buoyancy Aid before storing. Store in a cool, dry, dark place where there is good ventilation.
