Sunglasses sink fast, and they sink the moment you look down at the water.
A retainer costs less than a coffee and solves it, but there is one detail nearly every buyer misses: a plain neoprene strap floats only about fifteen grams of eyewear.
Most polarised sports sunglasses weigh more than that. With heavier frames you need a foam filled retainer or a bobber, not a simple sleeve.
We compared ten floating sunglass straps for paddle boarding, from the Chums classic to multipacks that work out at a dollar each, and sorted them by how much weight they will actually hold up.

The ten straps in detail
- Typeneoprene sleeve
- Length16 in
- Buoyancyfloats up to 15 g of eyewear
- Endslock-stitched, fit most frames
- Carequick drying
Best for: Light to mid weight sunglasses, and anyone who wants the proven one
Chums have been making this retainer since long before anyone called it a category, and it is still the reference. Sixteen inches of soft neoprene, ends that grip, and stitching that survives seasons of salt.
Know the limit, though. Fifteen grams of buoyancy covers light plastic sunglasses. Heavier polarised frames with metal hinges pull it under, slowly, which is worse than sinking quickly because you do not notice.
Weigh your glasses on a kitchen scale once. If they are over about 15 grams, take the DriftFish or the Neckz instead. It is a two minute check that decides whether the strap works.
Strengths
- The retainer everyone else copies, and the stitching shows why
- Lock-stitched ends grip almost any frame without stretching out
- Soft neoprene that dries quickly and does not chafe your neck
- Around eight dollars
Weaknesses
- Fifteen grams of flotation is not enough for heavy polarised frames
- Single strap, so a household needs several
- Typefoam filled retainer
- Material100 percent neoprene with dense foam core
- Adjustmentslider bead
- Colourshigh visibility
- Carewaterproof and stain resistant
Best for: Heavier polarised sports sunglasses on open water
This is the strap for the sunglasses you would actually be upset about losing. The dense foam core does the lifting rather than relying on the buoyancy of thin neoprene.
The slider bead is the practical touch. Tighten it and the glasses stay on your face through a fall, which stops the strap being needed in the first place.
High visibility colour is not vanity here. A floating strap you cannot see in chop is a strap you paddle away from.
Strengths
- The foam core is thicker than a plain sleeve, so it lifts more weight
- Slider bead means you set the length once and forget it
- Bright colours that are genuinely easy to spot on the surface
- Stain resistant, so sunscreen does not mark it permanently
Weaknesses
- Bulkier at the back of the neck than a plain neoprene strap
- Twice the price of the Chums
- Typeneoprene sleeve
- Endsanti-slip tube ends
- Fitone size fits most adults
- Waterfresh and salt
- Stylesmultiple prints
Best for: All day wear, where the strap has to be comfortable to stay on
Comfort decides whether a retainer gets used. This one is soft enough that you forget it is there, which is the entire point, since the strap in a drawer saves nothing.
The tube ends are the useful detail. Thin wire arms slip out of cheap sleeves, and these hold them.
Like the Chums, it is a sleeve rather than a foam block, so match it to lighter frames. Sun protection is not only about the eyes either, and our paddle boarding shirt comparison covers the rest of it.
Strengths
- The softest strap here against the back of the neck
- Anti-slip tube ends hold thin arms as well as thick ones
- Works the same in salt water as in fresh
- Sensible price for a single quality strap
Weaknesses
- Neoprene sleeve buoyancy, so heavy frames are borderline
- One size, so it can be long on smaller heads
- Typeneoprene, adjustable
- Strapsoft woven, adjustable length
- Fitall head sizes, men and women
- Colourshigh visibility
- Usesailing, fishing, beach
Best for: Shared use, where different people need different lengths
The adjustable version answers the one flaw of every one size strap: on a smaller head, the glasses hang loose and swing.
Set it short and the sunglasses stay on your face through a fall. That is better than any amount of flotation, because the strap never gets tested.
Bright colours again, and for the same reason. Once glasses and strap are in the water, colour is what gets them back.
Strengths
- Adjustable rather than one size, which fixes the usual fit complaint
- High visibility colours that stand out against water
- Same soft neoprene quality as the classic Pilotfish strap
- Reasonably priced for an adjustable design
Weaknesses
- Adjustment hardware adds a little bulk
- Buoyancy is good rather than exceptional
- Typeneoprene sleeve
- Materialpremium neoprene, waterproof and stain resistant
- Fituniversal
- Designsmany patterns and prints
- Testingused in salt, fresh, snow and desert
Best for: Anyone who would rather the strap did not look like safety equipment
Retainers used to look like something a lifeguard issued you. Ukes sell them as an accessory instead, and there is nothing wrong with wanting the thing on your face to look decent.
The material is proper neoprene, waterproof and stain resistant, which matters more than it sounds when sunscreen is involved.
Buoyancy is standard sleeve level. For light frames it is fine, and the strap's real job is keeping the glasses on you.
Strengths
- The widest choice of patterns, from plain to loud
- Soft neoprene that resists sunscreen stains
- Universal fit that holds thin and thick frame arms
- Well made for the money
Weaknesses
- Sleeve construction, so buoyancy is modest
- Prints fade after long UV exposure
- Typestrap with a separate bobber float
- Usefishing, boating, swimming
- Colourblue and green
- Designbobber adds buoyancy beyond the strap itself
- Fituniversal
Best for: Heavy polarised fishing glasses that a plain strap cannot hold up
Physics is the reason this exists. A neoprene sleeve can only displace so much water, and heavy glasses beat it. Adding a dedicated float solves the problem directly.
The trade is that you are wearing a small float at the back of your neck. It is noticeable, particularly lying back on the board.
If your sunglasses are the expensive polarised sort with metal frames, this is the honest answer. Everything cheaper is a compromise you find out about in deep water.
Strengths
- The bobber adds real buoyancy instead of relying on the strap material
- Designed around fishing, where frames are heaviest
- Easy to spot on the water thanks to the float
- Keeps working with metal framed glasses
Weaknesses
- The most expensive strap here
- The bobber sits behind your head and you notice it
- Typefoam tube core with knitted polyester surface
- Thicknessabout 10 mm
- Pack8 pieces
- Fitmost frames and brands
- Feelsoft, will not scratch lenses
Best for: Households, boats and rental fleets where straps disappear
Multipacks usually mean thin sleeves that barely float. These have a 10 mm foam tube inside a knitted cover, which is closer to the DriftFish approach than to a cheap sleeve.
Eight of them costs about what one good single strap does. Put one on every pair of glasses in the house and the problem disappears.
Rinse them occasionally. The knit holds salt and sunscreen, and after a season an unrinsed strap feels like sandpaper.
Strengths
- A foam core rather than a plain sleeve, so buoyancy is above average for a multipack
- Eight straps for around ten dollars
- Knitted polyester surface is soft on the neck and on lenses
- Easy to fit and remove between different glasses
Weaknesses
- Colour choice is whatever comes in the pack
- Knit surface picks up sunscreen and sand
- Typeneoprene sleeve
- Length40 cm
- Pack10 pieces in ten colours
- Fitslide the frame into each end and adjust
- Weightvery light
Best for: Groups, clubs and anyone who loses straps rather than glasses
Under a dollar a strap. At that price the question is not whether they are the best, it is whether they work, and they do for light glasses.
The ten colours are genuinely useful on a boat or a family trip, where four identical pairs of sunglasses cause more arguments than anything else on board.
Do not put them on heavy frames. Thin neoprene plus a heavy pair equals a slow sink, and these are for cheap sunglasses anyway.
Strengths
- Ten straps for around nine dollars, under a dollar each
- Ten different colours, so everyone knows which pair is theirs
- Soft elastic neoprene that is comfortable straight out of the packet
- Slide to adjust, so the fit can be tightened
Weaknesses
- Thin sleeves, so buoyancy is the lowest here
- Stitching is basic, expect a season rather than years
- Typebuoyant strap
- Pack4 pieces in black, blue, green and orange
- Fitmost sunglasses and glasses, adults and kids
- Adjustmentadjustable for a snug fit
- Useboating, kayaking, paddle boarding, swimming
Best for: A family where the kids need shorter straps than the adults
Four adjustable straps is the right size of pack for most families: one each, in different colours, without ten spares in a drawer.
Adjustability is what makes them work for children, where a fixed 40 cm strap leaves the glasses hanging around a child's chin.
Buoyancy is mid range, so pair them with light plastic sunglasses. That is what most people take on the water anyway.
Strengths
- Adjustable, so one pack fits adults and children
- Four high visibility colours in the set
- Sensible middle ground between single straps and giant multipacks
- Priced at around three and a half dollars per strap
Weaknesses
- Four straps at the price some brands charge for eight
- Buoyancy is adequate rather than strong
- Typewoven nylon and spandex blend
- Length11.8 in, stretches to 20 in
- Pack8 pieces in eight colours
- Fitmost frames, stretches to size
- Caresoft and quick drying
Best for: Small or narrow frames that slip out of wide neoprene sleeves
Narrow frames are the case that defeats sleeve straps: the arm slides in and back out again. A stretch woven strap grips instead, which is why this one is worth knowing about.
Short at rest and stretching to twenty inches, it holds the glasses close instead of letting them swing when you lean over the rail.
The trade is flotation. A woven strap holds less air than foam, so it is best on light frames, and best treated as a retainer first and a float second.
Strengths
- Stretch construction grips narrow frame arms properly
- Eight colours for around ten dollars
- Shortest strap here at rest, so glasses do not swing
- Quick drying, unlike thick neoprene
Weaknesses
- Woven strap floats less than a foam core
- Elastic loses tension after a couple of seasons
How to choose a floating sunglass strap
Weigh the glasses first: A classic neoprene sleeve floats roughly 15 grams of eyewear. Cheap plastic sunglasses are under that, most polarised sports models are over it, and anything with metal is well over. If your glasses are heavy, buy a foam filled retainer or one with a bobber. The physics behind it is simply how much water the strap displaces, and no amount of marketing changes it.
Fit beats flotation: The best outcome is that the glasses never leave your face. An adjustable strap pulled snug does that, and then buoyancy never gets tested. Straps with a slider bead or adjustable hardware are worth the extra dollar or two.
Colour: Bright orange, green or yellow shows up on the surface, black does not. This is the cheapest feature to get right and the one most often ignored.
Multipack or single: If your sunglasses are cheap, buy a multipack and put a strap on every pair. If they cost more than the board bag, buy the single foam filled retainer and stop thinking about it.
Frequently asked questions
Will a floating strap hold up any sunglasses?
No. Classic neoprene straps float about 15 grams of eyewear, which covers light plastic frames only. Heavier polarised or metal frames need a foam filled retainer or a strap with a separate bobber. Weigh your glasses on a kitchen scale if you are unsure.Do these fit prescription glasses?
Most do. The tube or sleeve ends fit almost any frame arm, and the stretch woven straps grip thin arms better than wide neoprene ones. Very thick arms on some sports frames are the exception, and there the wider neoprene sleeves work better.How long do they last in salt water?
A good neoprene strap lasts several seasons if you rinse it. Cheap multipack straps last a season or two before the elastic tires or the stitching pulls. UV is what kills them, so store them out of the sun rather than on the dashboard.Is a strap or a hard case better?
Both, for different moments. A strap keeps the glasses on you while you paddle, a case protects them in the bag afterwards. Losing sunglasses on the water and crushing them in a dry bag are two separate problems.Bottom line
For most people the Chums classic is the right buy: proven, comfortable and cheap. If your sunglasses are the expensive polarised sort, step up to the DriftFish foam retainer, or the Neckz with its bobber if the frames are heavy metal ones.
If there are four pairs of sunglasses in your household, the Decker eight pack solves the whole problem for about ten dollars. Whichever you pick, set the length short so the glasses stay on your face, and keep the rest of your kit tethered too, starting with the watch on your wrist.
