This thread has kind of jumped back and fourth between Gallets, Evo's, Bose, Headsets inc, etc etc.. So for those who might the on the fence a little betwen the brands and options I thought I'd jump back in and compare some things that I have noticed.
I think it's safe to say that I've flown pretty much every imaginable Gallet variant you could come up with, they are just
that good...
But when all the buzz started about the new Evo, I really wanted this helmet to fly (pardon the pun). First off, on principal alone , I would rather spend my money on an American made product than any other YMMV, and secondly, I am a firm believer that the more competition out there, the more the consumer benefits... So the last time I needed a new helmet, I pulled the trigger on an Evo. Here are some notes;
Weight... No matter how you configure them, Like for like, the Evo is always lighter. It is just a lighter built helmet. If weight is a factor for you (and ultimately it should be) the Evo is lighter. Unfortunately the Evo isn't magic, it's lesser weight comes with a couple sacrifices

A plus for Evo (sorta)
While the Evo may be thicker, looking at the two I can honestly say this would take a micrometer to discern. The reason the Evo is stiffer is because the Gallet has three strategically located relief cuts in the nape of the helmet.it is designed to flex there to ease donning of the helmet. If you put it on once during the course of the day, and use it once in a while, life is great. If you're like me and may remove it a couple dozen times a day, and wear it 330+ days a year… the ease of the Gallet is greatly appreciated.
Fit... Of course all helmets in this league are custom fitted, so if it doesn't actually fit right then you're not doing something right.. But that's not what I'm getting at. What I mean here is how the shell is made, and what it takes to make it fit. If you build an ANR helmet, (and I have no idea why you wouldn't) you are simply not going to be able to order an MSA Gallet shell of the appropriate size, and get it to work with the oversize comm equipment that goes with ANR. These shells were designed before the day of ANR. Consequently, if you were a size 7 1/8 ball cap, you will be ordering a shell that is good for an XXL head

Evo did their homework and pushed the ear cups out 1/2" This gives you the ability to fit ANR in the right sized shell, and not order a bigger one that gets 'padded down' everywhere else to fit right. Another plus for the Evo.. again sorta..
One negative to fitting the Evo is that they come with Boxell's version of an Oregon Aero Zeta liner. This is awesome if you live in Nome, but if home is more like the Sahara, you'll want something cooler like the Gallet comfort liner. Unfortunately the under liner (or lack there of in the Evo) makes utilizing other liner systems a challenge in the Evo. Booo Both come with several sizes of nape pads. Evo's all suck until you try their memory foam one. OMG! Why don't they all come with one of these? Gallet… take notes here.
Options and set up... Once again, ordered new, either of these helmets will be a custom build, So you'd think there'd be not much difference here, but there is one thing about the Evo that is worth noting. With a Gallet, you'll either get a single visor'd helmet (with an internal visor) or a dual visor'd helmet. With the Evo, it's pretty much the same, with the exception that you can have your single visor'd helmet come as an internal visor (model 052) or an external visor with a carbon fibre cover (152). This doesn't seem like much of a difference, until you try one on with glasses on. Having the external visor which is farther and a tad larger makes wearing glasses under your helmet much more friendlier.The only way to do this with a Gallet is to order a dual visor'd helmet and either deal with the extra weight or remove the inner visor you paid for
another plus on the Evo side.
Price… Price is about a wash, which is a little surprising since the Gallet has to come from France. Add ANR and either is a big ticket item
Sound… the stock comms in any of these helmets work, but they sound like your head is in a fishbowl. CEP's are the undisputed king if your ears and mission will tolerate them, and to that end either helmet will be using the same CEP's so a push there… ANR absolutely rocks for those of us that can't use CEP's. In this case the Evo shines. The helmet was designed form the get-go to accept ANR ear cups.
Which ANR is a personal choice, but a few tid bits; A20 clarity and sound is amazing. If you listen to music, you will love these, but beyond that the hype is just that. I can and have flown with HSI and Bose back to back. The HSI is every bit as quite, but has much more volume. (if you wear foamies under your helmet this will be important as the Bose will then just barely have enough volume to work) Lastly here, (and the only plus I see to the Bose) ease of interface with peripherals. Come on HSI, lets catch up to 2015…The blue tooth interface on the Bose will allow you to listen to music, take a call from a grower, and have it all mute when an important radio call comes in… This is the way it should be done…
Little odds and ends;
The comm cord securing on the Evo is bombproof, The Gallets works, but the Evo is better
Another nice comm touch on the Evo is the mic cord exit, (there is one) on the Gallet the mic cord was forgotten and the cord just has to be routed out the edge of the helmet
The securing strap ends on the Evo are aluminum vs plastic ones on the Gallet, nice touch, but the way the Gallet fastens down is a world easier than snapping and unbuckling every time. If the aluminum ones worked as easy this would go to the Evo, but for me the plastic ones get the nod.
Fit and finish, I hate to say it, but the Gallet is just a nicer finished product. Remove the liner on an Evo and it looks like the inside of a $.99 ice chest

The Gallet looks refined even when it's naked. I'm sure leaving the under liner off contributed to some weight saving, but this must be minuscule, what it also did was leave you with a much poorer interface for velcro on the Evo…. Booo
Soo… net net which one gets my vote? I'd say they're both pretty darned good helmets. The Gallet is definitely more 'refined' but the Evo has 'evolved' from it to be an easier to set up helmet. Price seems to be a wash, so for me it comes down to customer service and how much money stays at home, and in this case Evo got the nod

Sorry if that was pretty long winded, but some of these things are approaching three and a half grand, if this helps just one person pick the better choice it's probably worth it. If anyone finds it useful I can upload a few pics of the differing areas I posted on.
Take care, Rob
