Looks cool, but this thing is huge. I measured my head properly and ordered a large per size recommendations. I looked like Darth Vader from the movie Spaceballs with this thing on. Now I have to waste $8.00 sending it back for shipping. If you like Spaceballs this helmet is for you.
Way too big around the sides.
Its tight and makes your head look like a mushroom
I feel like Rick Moranis from spaceballs wearing it.
I'm glad this thing actually fits according to the sizing guide. But damn the shell is huge. I feel like I'm a stand in for "The Dark Helmet" in space balls.
Bought this helmet for my girl and she loves it. Fits good. Looks good. Great price.
I have a MASSIVE head, like size 8 1/8 hat size, so when I saw reviews saying this helmet was "too big" I thought that was perfect! But no, "too big" refers to the disproportionately massive shell for the small internal head fit.<br /><br />I've never seen/tried a more hilariously disproportionate helmet, it's essentially a joke.
Finally, a helmet to fit a Ferengi.
We had a wrong delivery. However, it was resolved within 15 minutes of reporting it. We tried three other helmets but even a larger s I We was too small. My grandson is 13 years old his 5xl fits great.
They are nothing like what I was looking for they are super huge looking I look like the guy from spaceballs the movie I was very disappointed
Too much padding. Sits off the head too high. Looks ridiculous
great helmet! light weight and looks awesome, super comfy
I purchased the chrome not knowing it had the black strip on it. I actually love it and the fit is perfect. It arrived faster than expected and in perfect condition. ????????????
I think these are cool . Fit good when worn properly and buckle is fastened . Always liked the German style helmets and this one looks just like it . It’s DOT certified so it’s legal to use on the highway . I bought it to look cool on my Cruiser E-Bike with my cool shades too . Padding seems to be well made for comfort and safety .
If you’re buying this I assume it’s to travel somewhere where one is required, not because you appreciate its safety features or you’d be looking at a full face. This bad boy is made well and can be worn all day with some comfort. I wear a Shoei RF1400 on my fast bike which is top tier comfort. Neither helmet makes me dread putting back on at the last gas stop often a long day of riding if that makes sense. The inner materials are great. I was in the Army and wore the older “k-pot”. This is a motorcycle helmet and while it looks like a military helmet, it has a different function and rides higher on the head due to this. Again, it has to function differently.
Great looking helmet, the fit is very acccurate. The inner lining could do with a retrofit as the seems push on my forehead causing mild discomfort on long rides. <br /> I would still recommend this for other riders.
Perfect for fat head like mine - sits on top of head nicely with just right amount of padding.
Returned it did not like how it fits gives you the mushroom head
Abe Lincoln hat, too high and wide I need to send it back
Great German style helmet. The helmet runs big, so order one size smaller than your usual helmet size. This will reduce that mushroom head. Also make sure you tighten the chin strap as tight as possible without being uncomfortable. This will help keep the helmet from moving upwards, specially on highway speeds. It's a great helmet and looks great wearing it with old school leather jacket and riding a cruiser motorcycle. Watch my video and see.
Good helmet
We needed a very large helmet. And it is big!!
This helmet is wonderful! Ordered a 3x - It was a B-Day gift for my husband. He loves it and it fits perfectly.
I bought it as a gift. So, I can't answer all the questions.
Is a terrible helmet. Is a cartoon sized stupid looking helmet that I would not recommend to anyone who wants a helmet to look good as well as function
Don't like it ,looks like a mushroom on my head, that's all I'm gonna say
It does give you a little bit of mushroom head, but what I found is wearing a neck gater over your face, reduces the perception of having a mushroom head. This is my second one, I got a gloss black this time. I had a matte black the first time. It works and gets me by. I don't really care what others think I look like.
Nice helmet, but due to my very large head it looked ridiculous on me so I sent it back
I was one size smaller L usually I'm xl. This is a large helmet with lots of padding but still worth the $ just for the cool factor. Ps you wont look like the the heros who tried too save the world.
Perfect Dark Helmet costume accessory. This thing is HUGE! If maximum mushroom head is your objective, look no further. Otherwise, well made with good quality. I'm returning because I don't want my fellow riders to turn me into a meme.
Really good helmet it makes your head look small
If I could no star it I definitely would. But I guess it gets one star for comfort. Mushroom head away!
Fits like a mushroom on my head very heavy not lightweight at all
Helmet is way to big if your looking for something light and comfortable do not buy this, waste of money more and likely will be returning it.
Love the new helmet my biggest worried was having something large enough for my fat head. I got the 5X and it fits absolutely perfect. Kudos to finally having something to fit my head.
Loving the visibility! Peripheral!
I ordered the wrong size, so it was my fault.
I love this helmet.It is comfortable and stylish !!
Love the Helmet. Looks, Fit, Quality,n Price.
Don’t like wearing helmets but this is a good one.
Don’t like wearing helmets but this is a good one.
Perfect fit, very comfortable for me. I like having a visor built in for shading my eyes. Replaceable liner is a plus. I like having the good spatial and audio awareness. I also like the classic "biker" look, though it may not be for everyone's taste. Folks complain about the size, but this helmet actually has real padding and protection. Great choice for hot weather.
Very comfortable helmet, meets all DOT requirements and breaths well in the warm Hawaiian air.
The quality and shipping speed is a win. No body likes waiting to get their stuff in the mail! And then receive cheap gear that doesn't look like anything you would have ordered. A1 in my books.
I love helmet. I didn't like camo liner.
Fits great, doesn't bounce around on my head. Looks even better than it fits.
I Never got it, please track it for me and give me updates it's been 3-4 weeks I'm sorry honestly but it's been so long
Inner foam is hard as a rock, most uncomfortable helmet I've ever put on my head.
Mushroom head, fit is terrible
Fits great. My old would last 20 mins and start hurting my head. This one I could have on hours and no hurt. I wish it was sleeker but 4xl isn't much sleeking to it.
Great fit and feel, happy with the finish too
Mushroom head like you wouldn't believe and it runs REALLY big. I normally wear an XXL and this was XL. Fit like a 4X would. I looked like Lord Helmet from Space Balls. Returned.
Love it,a little big,fits great but buckets big
It is better than a perfect fit on my head. Well made and very comfortable.
Fits good and tight-no parachuting due to the strap system. Very good quality on the features that matter. Overall-comfortable, sturdy helmet, true to size. <br /><br />The snap at the end of the strap isn’t a real snap. It’s two piece melted into the strap to secure it after you’ve fastened it. The button side broke in half and fell off after a week. I had to repair with super glue and it still broke off. The helmet makes me look like toad from Mario bros. I’m 6’1”/200lbs-I ordered a large and it still fits like an umbrella. For what it costs, I would expect it to be flawless.
Fits good! No issues. Does look a little oversized
Sono rimasto deluso e non lo consiglio, perché fa sembrare la testa molto grande
I love it and everyone seems to like it too. Everyone wants to know where I got it from.
It is very cool looking <br />& comfortable
This thing sat really high on top of my head. I looked like the guy from Spaceballs. I sent it back.
This helmet is MASSIVE. I feel like a space balls character. Mushroom head. Sits up way too high, and sticks out way too far. Definitely gonna be returning this. Don't buy this you'll look ridiculous
good product, didn't like it so i sent it back. BE AWARE...this helmet will look HUGE on your head. It is probably safe, but it may NOT be what your looking for. Remember "Space Balls" I cant get it out of my head now.
Nice helmet and it fits perfectly. A heck of deal for the price
Be alot better if it had a quick release helmet strap , also if it was a little smaller
The helment fits true to size and is very comfortable. It?s just freaking huge. It?s literally as big around as a 5 gallon bucket and makes you look like a bobble head. Very unattractive.<br />Very funny looking. Not low profile as advertised it is HUGE.
good helmet for the price, only thing they run a little big
MUSHROOM HEAD when asked where can i get one without the mushroom head the guy answers my question with a question.....why would you want a low profile one? .....wtf.....CAUSE I DO....
Bought one for myself and my brother, wanted a half helmet that fit more down in you head
Fit well and was everything it said it would
Look no further this the vest you want this the vest you need
I have no complaints whatsoever. Great by for the price.
Very comfortable. The tying part can be a bit if a challenge if you don't know what you're doing. Just think it needs better instructions.
Awesome helmet just way to big
I got a Xs becouse I have a small head but this helmet is very bulky on the top and a little heavy for a small helmet I would have been happy knowing it would have protected my skull. But it was just too bulky and gave me a mushroom head look. Only reason I gave a one star was the bulky mess it fit well though so sizes are right.
sits to high on my head and looks like a mushroom, great looking helmet but.... for a medium it just doesn't fit right.
I have not even made 8 months yet with the helmet and the strap came off ... super unsafe.
I bought my first one of these helmets a year ago. I got rear ended on my 2005 Softail Standard last August. I was doing 20 mph, the car that hit me was doing about 60 mph. I hit my head pretty hard, at least once. I'm alive, and riding again this year, because of this helmet. Great product. I bought another one when I bought my new bike this spring.
The helmet fits well. Its comfortable. It is more low profile than my last helmet
it is the right fit that i was looking for.
Great fit
Looks a lot bigger on my head than expected. Fits good but looks oversized. The term they use called mushroom head??. If something can be done about that.
Very nice loocking helmet, top material used and very confortable.
These helmets do run big. I ordered a L and it fits perfectly! Any other style helmet I wear an XL.
Love it Durable and comfortable
3x way to small this 4x is little big but no half size that all I like any ways will use the shit out of it
Comfortable fitting and looks great.
This helmet is awesome. It's DOT approved and stylish as hell. Only one small issue, I have a Harley Davidson half shell that's size medium and fits well so I ordered this helmet in size medium and it's just a little to big but I make it work.
Ordered the matt finish and received the shiny finish instead. Fits very well. Not happy with the old school strap loops. Wish it was quick release instead. Larger than I expected also.
Bigger than you think. Looks good when riding though.
Very comfortable and offered plenty of room for goggles.
The helmet was every bit as cool as I hoped! I will only be using it for trail riding, but I will feel much safer and "stylish" using it.
The photo looked exactly like the picture and it was a great fit for him
Both mirror came broken still have not got my money back
It?s like A 1 spice on a burger
Fits great and comfortable.
Very happy with style and fit.
Looks great!
I normally rock a $1000+ Shoei full face but wanted to get something open face that I can wear with a bandana.<br /><br />For the price I was really surprised just how well this helmet fits my boof head (4XL)
Fits great and looks better. I’ve wanted this style helmet for years and finally got one when I bought a new motorcycle.
It's perfect except when the old lady tryna get all cuddled up will riding b**** her helmet hits the back of mine where it's got a lip rim and hers is full face
I love this helmet...
I'm tired of looking like one of the Spaceballs, so I got this hoping it would be lower profile. Now I just look like Dark Helmet. I got a large at first because my head is between size 7 1/4 and 7 3/8, but it was too loose so I returned it for a medium which fits better, except the Y of the straps don't fit under my ears. Quality seems ok, but I'm not like "excited" to wear it, so I give it only 4 stars.
Love it!
Very solid helmet very good pice fast shipping
Sucks
I have a big head size 8 fits great
I did not receive the item in time, as promised in the delivery, therefore do not have it - and paid for it!
Like it, what I was looking for
I NEVER received this order. Can someone please contact me for help???
I like the helmet can't wait to get on the road!
Good item. But I don't like it.. it's my fault that I got the wrong size.. I will buy another helmet from this company. I like the quality..
Hi I never received this item
Fits great. Looks great
Fits great. And quick shipping. Straps are the only thing I would do different. Definitely worth the buy
Great fit and you can tell it’s DOT 😂 thick and what I wanted!
This is a great looking helmet. The inner lining is super comfortable, soft, pliable, yet sturdy enough to handle a significant impact. The matte black finish of the helmet hides dirt, and is resistant to light scuffs. The only thing this helmet needs is a quick closure chinstrap.
Very easy to deal with and easy to return items!!
Really bulky not light weight at all
The picture is a little misleading as it looks smaller than it actually is, the helmet itself is good quality but again is a bit bulky.
A little tighter than I'd like, but hope that it breaks in. Besides that, looks really good, getting lots of positive compliments. The flat black really makes it look awesome.
Returned it it was too bulky of a helmet. I was looking for a low profile german style.
Way too big. Not what I thought
Love it
Nice helmet DOT and fast shipping
Great Helmet fast delivery!
Fit great nice helmet design, just sits way to high on head. Looking for a more low profile fit.
It Is Exactly What I Was Looking For Very Good Quality At A Very Good Price With Very Fast Shipping I Recommend It One Hundred Percent
I purchased an XXL. For the first time, my skull and the meat around my head doesn't feel constricted The helmet is so large it looks so visible on the road. Almost to the point of ridiculousness. Also It is great again sun.
Safe, nice, good quality. It's difficult to buy such a good half German style helmet in China even it's made in Taiwan. Shipment is really fast that only took me 10 days.
I had to get a 5X for my bid head. Very comfortable fit. I’d buy it again.
Great looking helmet it ticks all the boxes and the boys love them.. totally recommend this style.
The helmet fits great and looks awesome!
The helmet looks really good, but sits too high on your head. I returned it immediately, partly because of the Darth Vader look and partly because it was too large. Not a bad helmet though, just not what I am looking for.
Great looking helmet for cruising.
A helmet is necessary to buy in person I thought I was gonna look cute in this but I look funny like a big mushroom.
Looks and fits great. Only thing is it's not beard friendly. When I go to tighten or loosen the chin strap I always snag my beard hair in it
Cool helmet. Fits well and looks good.
Unable to use, did not fit my bike. Website said it would. Was disappointed I couldn’t use it. Hoping for another option.
I normaly wear XL but with this brand had to get Larg keep that in mind when ordering
Was looking for more of a thinner helmet but am happy with the comfort and style of this helmet.
great helmet
Seems to run 1 or 2 sizes small. Had to return. The lining looks to be a bit on the cheaper end. Could at least be glued down.
Great helmet, sizing was accurate and looks great and comfortable when riding at speed. Awesome.
Size runs just a tad larger than normal, extremely comfortable and well made , just buy it ,
''Helmet was exactly what I wanted, and fits perfect. also good pricing, I'm looking to buy my wife one also''
