The promise of a three-quarter helmet is simple: most of the airflow and view of riding bareheaded, with a shell between you and the road. TRIANGLE's retro entry adds one more feature to that pitch, a drop-down tinted shield built into the shell, and it prices the whole package below most of the certified competition.
That shield is also where the decision gets complicated. Tinted plastic sitting an inch from your eyes has to cooperate with glasses, hold up after dark, and stay on its track at speed, and owners' answers to those three questions don't all point the same way. Five of the fifteen written reviews on this listing turn on the shield somehow.
There's a smaller question underneath, too: what the DOT mark on the shell actually certifies, which is less than most buyers assume. Below, what the ratings and the written record agree on, which listing claims hold up against it, and how the sizing runs.
A retro 3/4 helmet with one selling feature, and five texts that found its limits
The TRIANGLE 3/4 open face motorcycle helmet sells for 64.99 on the Matte Black Medium variant, with other sizes and colors priced separately, which puts it in the cheaper third of the 257 helmets we track. Our helmet table shows where that price sits against everything else on the list, because the price band is the one part of this pitch nobody argues about.
The rating record is strong for the money: 4.5 stars across 359 ratings, 74 percent of them five-star and 3 percent one-star, which is a confident spread rather than a polarized one. Every text captured for this review carries the confirmed-purchase badge, so the agreement you're about to read comes from people who paid for what they're describing.
Where the record keeps pulling you back is the helmet's own best feature. The drop-down tinted shield is the reason most of these buyers picked this helmet over a plain open face, and it's also where five separate complaints live, from glasses that won't fit under it to a visor missing from a box marked brand new.
The drop-down shield sells the helmet, and it is where the returns happen
The shield complaints form the clearest pattern in the record, and they start with the most-voted text. That text carries five helpful votes, praises the comfort, the padding, the paint and a shield that holds the up position firmly, and then reports returning the XL anyway because the tinted shield wouldn't clear their eyeglasses. They also remembered seeing a glasses-friendly claim, and no such claim appears anywhere on the captured page.
Night is the second limit, and one owner states it flatly: the visor is not to be worn after dark, and their advice is to keep a pair of clear glasses for night rides. A different owner found the tint light enough for their eyes, so the darkness question doesn't have one answer in the record.
The mechanism itself draws two more complaints, one describing a shield that flexes and tries to disconnect if pulled down too hard, another reporting a visor that simply won't stay on.
The last problem isn't the shield's design but what showed up in the box, because one owner opened a package marked brand new and found no visor inside at all. A separate owner describes a carton that arrived well worn and covered in dust. Five of the fifteen written reviews carry a shield problem of some kind, which is a strange record for the feature doing the selling.
Glasses wearers should treat the shield as the deciding question and check the return window before ordering.
What the DOT mark covers on a three-quarter shell, and what stays exposed
The listing claims the helmet meets DOT FMVSS-218, the US federal motorcycle helmet standard. That standard is certified by the manufacturer, not tested by an agency before sale, so the mark is a legal claim with an obligation behind it rather than a test report you can read.
A three-quarter shell explains what that certification does and doesn't cover. It protects the ears, cheeks and back of the head, the same rear coverage a full face provides, and it leaves the chin and face with little protection, even from non-crash events. That trade is built into the open face design, and picking this look over a full face is how a buyer accepts it.
Construction is an ABS shell over a suede-lined interior at 3.34 pounds, with a 1-year warranty row and a storage bag included. The spec rows don't name the foam liner type, which is the layer that actually absorbs an impact.
Only one owner account touches impact, and it should be reported for what it is. An owner who fell from their bike has said they felt secure in the helmet, which is one person's experience of one fall, not a test of the shell.
Two bullet claims the record contradicts, and one nobody has tested
Two bullet claims run against the record, and the wind noise one is the clearest.
The listing credits an aerodynamic shape with minimizing wind noise, but one owner reports noticeable wind noise, and another says that over 70 on the highway the helmet picks up a flying nun effect that pushed them onto back roads. The same highway account sits awkwardly against the first bullet's promise of hours of comfortable highway riding.
The 99 percent UV claim on the sun shield has no test behind it anywhere in the record, so it stays a manufacturer figure rather than a measured one.
The two three-star texts fill out the picture without changing it. One describes a cheaply made feel with very little padding, a bulky shape and a well-worn carton, then still calls the helmet good looking and easy to return.
The other is the missing-visor account from the used-as-new box. Both sit inside 8 percent of 359 ratings, and neither reports a safety problem.
Daily-use owners, the strap, and the sizing question left open
What the record agrees on is narrower but useful. Two owners describe daily or near-daily use, which nothing else contradicts, and style praise runs through the five-star texts, from old-school graphics to a jet pilot comment about the pull-down shield. Price-for-quality gets named directly more than once.
The quick-release strap earns two mentions, one owner calling the quick-snap style very adjustable and the most-voted text noting theirs already had the updated release buckle.
Sizing is the open question, and the texts point in different directions. A medium wearer sits between sizes and says they could probably have taken a large, a Spanish-language owner reports the fit is barely the measure, and a third says the brand's sizing runs off compared to others without saying which way. Measure your head circumference just above the eyebrows rather than ordering from a hat size.
This suits a scooter, moped or back-road rider who wants the retro look and doesn't wear glasses under the shield, and the 70 mph account is the reason highway commuters should look at a full face instead. The helmet table keeps the price band honest against the rest of the category.
Frequently Asked Questions
Can you wear glasses with the TRIANGLE 3/4 helmet?
Treat it as unresolved. The most-voted review is a glasses wearer who returned an XL because the tinted shield wouldn't clear their eyeglasses, and the captured page carries no glasses-friendly claim, though one owner remembered seeing one.
A second glasses owner kept theirs, though their visor was the one piece missing from the box, and rain coverage over glasses was what they had wanted it for. Check the return window before you commit.
Is the DOT certification independently tested?
No. FMVSS 218 compliance is certified by the manufacturer rather than tested by an agency before sale, so the DOT mark is a legal claim the company stands behind. The shell is ABS over an unnamed foam liner, and the only impact account in the record is one owner who fell and has said they felt secure.
How does the sizing run?
Three texts point in different directions. A medium wearer says they could probably have taken a large, a Spanish-language owner reports the fit is barely the measure, and a third says the brand's sizing is off compared to others without saying which way. Measure your head circumference above the eyebrows and ears, and don't order from a hat size.
