Lightweight helmet, MIPS technology
351444
I purchased this helmet after intense comparison since it's purpose is really important, to protect my kid's head.
It's more $$$ than some others, but again it's balanced against what it's being purchased for.
This Giro helmet is built on Multi-Directional Impact Protection System (MIPS) technology and that is the reason I purchased it.
It's really light, My kid has no complaints about this helmet and will keep it on. (won't work if they don't wear it).
I'm going to purchase another when we have to size up.

I actually returned this for a flat-black version, but the point remains you can't get a better helmet for the money. I like the modular design. With the included sun shade, I don't have to take carry two pairs of glasses. I added the optional brake light and it seems to have had an impact on the cagers: they stay a little further back at stop lights and signs.

This is a great helmet. Very comfortable and quality built. I appreciate the extra potential safety feature of MIPS. I highly recommend this helmet.

I bought the Winter Kit separately from the helmet itself. There are no instructions but with a little thinking you'll be able to put the two adhesive strips onto the sides of the inside of the helmet in about 10-15 minutes, and the rest of the removable kit goes on and off in 5-10 minutes.

Something to keep in mind is that it does make the helmet smaller. If you are close to the limits of the helmet size you have, you may find that putting the winter kit in will make it quite a tight fit--especially when it comes to your forehead and the helmet straps. I found that I needed to take out the detachable visor to gain a bit more headroom.

All that said, I did pick up two kits for my two Sutton helmets (one with and one without MIPS). I only installed it on the non-MIPS version (because it's already a tight fit without dealing with the MIPS system), but that's turned out to be handy. Rather than constantly deal with taking five minutes or so to get everything in place and adjusted with changes in the weather, I just switch helmets.

This Helmet is light weight and real comfortable. The latching mechanism for the face shield works great. It was easy to install my Chatter Box GMRS X1, mic and Speakers into the helmet. I also noticed with this modular helmet that I have better side vision than I do with my other Modular helmet. I am planning on buying another Vega Summit II helmet for my other touring bike in Black. Great helmet. I recommend this helmet.

ANSI Z89.1-2009.  I First saw these on a European based U2 crew, when I worked the U2 360 Tour in 2011, in Philly & Baltimore. I originally bought a Petzl climbing helmet - because it has a chin-strap- after I saw a guy's hard hat come off his head in a fall. Dude got hurt, badly. When my Petzl helmet (which I like very much) began to get old, I searched and found the Kask on Amazon.  It's light and comfortable. I have yet to wear it in hot weather, but it does have something like 10 screened vents. If you are a professional, and value safety (and your head), cough up the big bucks for a Kask helmet. Made in Italy. Design Capitol of the world. At 100.00 PLUS, it's expensive, but worth it. You're not only going to protect your head in style, & be in compliance with the highest of safety standards for hard hats/helmets, you'll look like the pro you are.

This mask is a nice economical upgrade from your disposable face masks, with a better fit, and gives you the capability to use a whole variety of chemical cartridges as well. The silicone material used in this model is more comfortable compared to the cheaper 6000 series and I like the fact that the exhalation valve is pointing downwards to reduce fogging of your goggles.

It has some shortcomings, however, which make me wish I would have purchased the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/3M-7500-series-half-mask/dp/B008MCUULW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">3M 7500 series half mask</a>&nbsp;(in a larger size) or perhaps even the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/3M-full-face-piece-6000-series/dp/B007JZ1M10/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">3M full face piece 6000 series</a>&nbsp;instead:

After a few minutes of use this mask starts to hurt the bridge of my nose, especially once I get sweaty, as this makes the piece slide down slightly. The rest of the mask fits comfortably, but I have a pretty big nose so perhaps I should have gotten the large size instead of medium (for reference: I am a 510, 155 lbs male).
A proper fit and seal changes with the angle of your head/neck: if you have a good fit looking straight forward, the lower part of the mask loosens once you look down. Or vice versa: a proper fit looking slightly downwards becomes uncomfortably tight once you look forward or up. This is caused by the simple design of the lower strap behind your neck and I guess this will be much less of an issue with the full face masks.
The quick latch mechanism is only useful if you wear a helmet (you can lower the mask to talk/drink etc. without removing the helmet). Otherwise it is just as simple and fast to remove the head strap to lower the mask (it will stay hanging on the neck strap).
The mask itself (probably the silicone) has a bit of a new car smell. So even with chemical cartridges filtering the outside air, you will notice this smell inside the mask.

So overall its still a nice, economical and versatile upgrade over the disposable dust masks, but its not perfect and made me looking into one of the more advanced 3M models such as the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/7500-series-half-face-piece/dp/B008MCUULW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">7500 series half face piece</a>&nbsp;or the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/6000-series-full-face-piece/dp/B007JZ1M10/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">6000 series full face piece</a>.

A very lightweight and comfortable flip up helmet. The first thing you notice when you don this helmet is how comfortable it is, especially on your forehead, where a thick foam wrap bears most of the weight. I wear glasses and this allows plenty of airflow to prevent them from fogging up. It uses standard 4 1/2 x 5 1/4 lenses which generally cost $2 to $9 depending where you buy, and has built in support for "cheater" magnifying lenses. This will be used primarily for gas welding, but is suitable for MIG/TIG/STICK also. Keep in mind that for $11.56 you are getting just the helmet. You will need to purchase shields and lenses separately. Made in the USA.

This is a lightweight (yet durable) helmet at a very reasonable price. I had an Arai full face but without the chin guard lift up feature. It was heavy, uncomfortable, and fogged up a lot. This helmet is very comfortable, doesn't fog, and having the many options with the face shield and sun visor, and chin guard positions/ operation make this a great buy!

This helmet is pretty cool and versatile. At first I was worried about it impeding my peripheral vision however those fears went away after I took a ride wearing it. I'm very happy with the purchase.

I can't believe that we paid less for this than we would have for a lesser quality helmet at the local 'discount' superstore. It fits very snug yet comfortable due to the clever built in adjustment knob. Additionally, it is incredibly light weight. One thing in particular that I like about this unit is the low profile design. No doubt there are options available that are more streamline but NOT in this price range that I could find. Many of the lower priced helmets that are available look somewhat ridiculous due to what I see as 'over designing'.

Lightweight and comfortable, just what I was hoping for in a good helmet.

Lightweight, breathable, and comfortable. Looks cool. Love the visor and the adjustment knob.
If I had any complaint, it would be that the stick on piece for the goggle strap holder doesn't stick as well as it should.
The headlight/action cam mount kit is a cool addition if you want a helmet-mounted light.

I have about a 22.5" circumference head, and had to use the dial to loosen it up almost as far as it would go to make it fit correctly, but it fits well enough now although the ear loops were a little hard to get right. Because the helmet is unisex, it might not fit very small or very large heads well. Ventilation seems pretty good, although it is a bit noisy on the road. Consumer Reports rates it excellent for its impact rating, although note that this is not a MIPS helmet, which my next helmet will most definitely have. I should mention the visor does seem a bit flimsy- one of the 4 tabs broke off in the hole as I tried to remove it (note that if you remove the visor, there are 2 holes left exposed on each side of the helmet that don't look very nice). But for me, it works quite well, was a good price at $26 (I've seen it at a number of other places for $45), and I like how it looks for the most part.

Nice helmet, good price, fast delivery. This helmet is very comfortable to wear. Would definately buy again. This helmet is not as "cheap" or "unsafe" as some reviewers would lead you to believe. All helmets are only good for one direct hard impact and should be inspected and probably destroyed after that. This helmet would definately protect my head for "the one" impact. Try not to go head first into an oncoming car, it won't protect you. Very pleased with purchase.

I'm glad MIPS helmets are available.  I have this one and I have one for road-riding since a mtb has more safety features.  I used to use one helmet for road and mtb, but the circulation in this one s not what I'm used to, so I bought a Giro road helmet with MIPS.

These MIPS helmets seem to run big.  I typically wear a medium helmet, but after this was a little loose, I bought a small road helmet.

My initial assessment of the Champion Hockey Style Catchers Helmet is it is a very lightweight and ridged product. It does what is it intended to do in protecting your head. Our league requires that you also have a Throat Protector, so we had to purchase that separately. The open back design makes for dawning and removing of the helmet very quick and easy. The adjustable satraps also allow for quick adjustments. My daughter (16) normally wears her hair in braids which requires adjustment for proper fit. This is really a one size fits all type helmet, but look at the size chart to see if it covers your size. The straps on the back also have snaps that allow the back guard to be removed completely from the helmet for cleaning. The pads inside the helmet are extremely soft and comfortable yet firm and take the shock of a direct hit to the head. My daughter has been hit a few times and does not appear she is any dinger than normal, haha just kidding. She has not been injured or shaken from the direct impact of a pitch. The pads inside are also removable for easy cleaning. The face mask is very secure feeling and allows plenty of peripheral vision for her to see the action to her left and right.
I will update this review should she experience any issues with using the product and provide any addition information we learn while using it moving forward.
