Okay I have been wearing a Giro Air Attack Shield for about 4 years now and it's the best helmet I've ever had however Jay recently bought a cheapie helmet that looks like a Giro knockoff and really liked it so I did the same thing
 
Here's the helmet, looks almost exactly like my Giro
 
https://www.amazon.com/gp/product/B0731LNRJ3/ref=oh_aui_detailpage_o08_s00?ie=UT F8&psc=1
 
Grand total $32.97 so it can't compare to a $200 Giro right? well yes it actually can...
 
The fit and finish isn't quite as good as the Giro, maybe 95% there and it's not uncomfortable on my large lizard head
 
Ratchet is a large round knob that's actually easier to adjust than the Giro AND on occasion while riding with the Giro I had to push it forward but never had to do that to the Basecamp
 
Front shield held onto the helmet by 3 magnets which appear to be much more powerful than the Giro but the magnets rattle if you move the shield around, this isn't an issue during the ride
 
Front shield is larger than the Giro's and the view is GLORIOUS! Maybe because its new and not scratched up yet but I was impressed, slight optical distortion around the nose area but you don't notice it while riding, thought it might touch my nose which would be annoying but it never did
 
Shields are about $18 compared to the Giro's $40, I even tried mounting the Basecamp shield on the Giro but the magnet polarity is reversed and they repel each other, bummer
 
Not bad for $33 bux

Nice looking.  After checking it out it also appears there is a more open design similar to a conventional road type lid withthe shield as well.  Price point in in the $39 range

I've never had a problem with needing a more open design, I've ridden the Giro in +100 degree weather and never felt hot in fact it worked better than my previous open air Giro, might be because it provides more shade?
 
Basecamp also makes a shield that integrates in the shell and apparently pulls back inside the helmet although I can't find them for sale in the US, looks interesting but might be fragile

I have the red version of that helmet. I like the fact it doesn't slide down and let the shield ride on my nose, like my three GIRO Air Attack Shield helmets do. Very comfortable helmet with some nice features. A real bargain at $40. These are not "one size fits all" helmets, so when ordering them off Amazon, pay attention to the head diameter range listed under the helmet description.
 
I'm going to order more of them in different colors. I could order six of them and the total dollar amount would still be less than what I paid for my first Air Attack Shield helmet.

Jay you need to start with this one for your collection: https://www.amazon.com/Basecamp-Children-Skating-Protective-Crocodile/dp/B01N4C0 GU2/ref=sr_1_12?ie=UTF8&qid=1501189120&sr=8-12&keywords=basecamp+bike+helmet

Jim, I'll wear one of those helmets after I install a surrey top on my trike.

Wrap the tape measure behind your head and around your nose.  (snicker, snicker!)
 

Heck I'd wear it on the HHH 100  it would be all that more entertaining

I know. I too am sometimes very helpful...
 
I have been to a requisite Barbecs breakfast and a ride after, so does that technically make me a Clown as well?

Ordered another BASECAMP helmet. It's 2 oz. lighter than my white GIRO helmet, and $225 cheaper. The tinted shields on both helmets are polarized.  
 

 
$259 GIRO Air Attack Shield helmet on left. $34 BASECAMP helmet on right.

Now I have to find a different color...can't match Jay. He has no love for surreys.

"...I also got the yellow lens for low light conditions."  It's amazing how those yellow lenses enhance your vision under low light conditions. I have a pair of clip-on yellow lenses I use on my glasses.
 
Wore my safety-yellow GIRO Air Attack Shield helmet, riding in Richardson and Collin County traffic this morning. This was the first time I've worn one of my GIRO helmets, since I purchased my first BASECAMP helmet. The shield on the GIRO helmet is too close to my face and jacks up my glasses to where I'm looking out of the middle portion of my trifocals. I'll only wear one of the GIRO helmets in an emergency in the future.

yeah i'm not sure I'd be up for that ..  the shark though .. that I could get into ..  Unfortunately they don't make one in the right size for my fat head.  
 
I'm pretty sure whatever certs it would have are illegitimate too .. but I'm not sure that bothers me so much ...

From someone that makes a living importing things from china ..  never trust a sticker (or any other certification) coming out of there without verification.    Products aren't the only thing thats faked.      I've seen some pretty amazingly well done certification forgeries. Heck there are places in the Canton Fair http://www.cantonfair.org.cn/en/index.aspx  that will sell you whole compliance testing (on paper)  for pretty much anything you want.     I made a joke once about getting some Level VI ballistic penetration certs for the spandex stuff we sell and seeing if we could market it to certain politicians and regimes.  Unfortunately, if effective,  such a market would only be short duration, not much reoccurring sales.  
 
A good sign of a fake compliance situation is when you find a other-country-sticker in the box rather than your own.   Can't get customs to pull your stuff for that, they won't care.
 
IMO (and I've looked)  EN1078 is better than CSPC/Snell    Europeans take this stuff seriously.   Thats why I'm buying helmets in the EU now and not the US.

Now that made me laugh Jay! Haha. I only wear my helmet to be a role model for my grand kids. This old hard head would break the anvil. I really like the helmet, thanks Jay and Mark.

This helmet might be my winter helmet as it does not have many vent holes. I may also pick up one like this: https://www.amazon.com/gp/product/B073FJY5PM/ref=ox_sc_act_title_1?smid=A1S7T1ZU 8V1Q4S&psc=1
 
My video review:

Here is my second Basecamp helmet review. I neither endorse wearing helmets or condemn their use. https://youtu.be/DVf8IBHVBbA

I just got mine in the mail yesterday.  Looks and feels great.  Thanks for the info and review guys, I had been looking at the Giro, but hated to spend the $ for it.  I also ordered the retractable lens model, it hasn't arrived yet and I'm anxious to compare the two.

Will do!  I ordered it from Ebay as it was about $20 cheaper than Amazon.  Downside is that shipping will take longer.  It does come with the three face shields.

Figures...

I finally received the Basecamp sliding visor helmet.  I ordered it thru Ebay ($36.99 plus $3.00 shipping) vs Amazon ($54.84) as it was cheaper; however it took over 3 weeks to arrive from China. The removable visor Basecamp helmet weighs in at 291 gms w/visor attached and the sliding visor Basecamp helmet, the pink one, weighs 285 gms.  The sliding visor comes with three different visors, gray, yellow and metallic (flash).  The sliding visor works well and is easy to remove and change out between the other visors.  The sliding visor is shorter than the removable visor and covers less of your face.  The sliding visor helmet is somewhat longer and more bulbous in the front, making it less aero in my opinion, than the removable visor helmet.  My major complaint with the sliding visor helmet is that it will not clear my glasses, so I cannot wear my glasses while wearing this helmet.  The removable visor helmet however works well with my glasses.  The metallic (flash) colored visor works great in bright sunlight, better than any other colored lens or visor that I have used.  One unusual thing that the sliding visor helmet has is the chinstrap lock.  I have included photos, it has a clicking mechanism, similar to some I have seen on some bike shoes.  Please note that I purchased the sliding visor helmet in the "hot pink" color for my wife.  I quit wearing that color many years ago. LOL  Both helmets are very adjustable, as my wife has a small head, and I have a large head (due to such a huge brain, I am sure) and we are both able to wear either helmet.
 


 

Looks like they are about  $19 on Amazon Jay. If they are darker, I might get one as well.

Let me know if they are darker. I have one in my cart...

All good...second opinion.

Well, I guess they're all gone. Can't find them on Amazon or eBay. Oh, well.

Thanks Jay. Exactly why I don't like all the "smartness" of search engines trying to only show me what they think I want!
