Fire iridium is not for night. They are for super bright sunny days. For night, use hi-yellow, or another lens with a higher VLT %.

For night... H.I. yellow is better than HI persimmon.
I have both lenses. I use the HI persimmon for mostly cloudy days and the HI yellow for snowy days and night riding.
I'd get the H.I. Yellow lens for night

Yes, this is the 20' model. The less expensive version is the 10' model. But, the 20' model is capable of pulling at much faster speeds.

Pretty sure it goes like this:
Small=7 1/8 medium= 7 1/4 large=7 1/2 and XL=7 5/8

Bummer because I'm a 7 3/8 and grenade never makes 7 3/8 hats :(

High Intensity Yellow is great for overcast and night time. It has 81% light transmission so its good. I use it for night and low light conditions.

fire iridium is good for super bright sunny days

fire lens is probably the best for super bright blue-bird days. But theyll probably be too dark for anything other than super bright sun.

yea itll still work. frame shape hasnt changed at all.
foggy? well my favorite low contrast lens is the High Intensity Yellow lens.
I use it at night and in fog and overcast. It has 81% light transmission i think so its good for those darker low contrast conditions

Im 6' 190 and I have the XL. It fits pretty big. I would have been fine with the L. But I have gotten used to the baggy feel of the XL and I like it. If you want more baggy, get the XL, less baggy get the L.

yes. it doesnt have a snap like some helmets do, but it works well.

Hey.
I have had the Smith Holt helmet and the Maze helmet and I use crowbars 99% of the time. No gaper issues (check my pic in my profile: holt + crowbars). The Variant is def a 'skier' helmet though. Check out the Maze or Holt for sure.

Hey.
yea the hi yellow is awesome for low contrast, low light and night time. It has a 81% light transmission so it lets in a fairly large amount of light.
i think the g30 is only around like 30% so the HI yellow would be better for night.
H.I. Yellow or clear are the way to go for night.
hope this helps

I have used goggles from dragon, smith, oakley, quiksilver and spy with this helmet and never had a problem.

It says 'genuine leather' which primarily means cowhide. So chances are, yes, this is most likely made from cow leather.

Well for mirrored in the daylight, I prefer the black iridium lens, but with only an 18% light transmission, at night you can't see much.
The black iridium is awesome when its bright, and I use the H.I. Yellow lens for night time and its great. It's not mirrored, but is great at night and in low contrast conditions.
I dont really know if oakley (or anyone for that matter) makes a type of lens that youre looking for (mirrored in daylight but still be able to use at night / mirrored lens for low light and night).
Perhaps Pink Iridium would be your best bet? My girlfriend has pink iridium lenses on her stockholms and she wears those at day and night. theyre not 100% mirrored, but like maybe 40% mirrored.
hope this helps bro
take care

They aren't very warm. I only wear these riding if its a warm day (like warmer than 35 degrees F (~3 C). I would not recommend them for a -10 C day (14 F). You will have very cold hands. These also have no waterproofing. Your hands wont be totally soaked, but they wont be dry. I've worn these with it was about 28 degrees and freezing rain out and I was miserable.
Don't get me wrong though. I love these gloves (on a warm day). I wear them to work and when I'm walking around town and going out to the bars and stuff. They're comfortable and I get compliments on them all the time. They're just not made for snowboarding on cold winter days, they're made for spring.
If you want a pair of grenade gloves that are warm, I suggest the sub-zero gloves.

This board is good for everything; all mountain, pipe, etc. Its a directional twin so if he's a big-time freestyle rider you may want to consider something that's a true twin. But, if he is an all mountain rider as you say, this could be a perfect board.

My buddy has a pair of 'crash-pads' (essentially the same thing but just made by a different company). He wears his boxers and long underwear (if he needs them) under his crash pads, then his pants on over his crash pads. This makes it easier for changing into and out of them. Also, if you scare the crap outta yourself, you wont leave evidence in your hip pads ;). Hope this helps.

I have Fuse and Prodigy goggles with sensor mirror lens. I ride a lot at night so I have the sensor mirror lens, but I've also used these a lot during the day. The lends is excellent at night. I'm not gonna say they 'work well' in sunny conditions, but they'll work. With a 70% vlt rating, they let a fairly large amount of light in. A more versatile lens would maybe be the gold at 42%. However, if you want maximum performance from the lens, I suggest getting the sensor for flat light, low contrast, and night riding, and probably the platinum mirror for brighter days. But the sensor mirror will work during the day :)you just might be squinting a little. hope this helps

I use the H.I. Yellow lens for night time riding. (High Intensity Yellow).

In terms of size and fit, I think these are probably a little larger than A-frames. I probably have an average size face and prefer the fit and wider peripheral vision of the Crowbars over the A-frames. But it really comes down to personal preference. I would try them on at a local shop or something before you buy them.

I am 6' tall and usually wear XL pants. I have these in a Large and they have a good amount of 'bagginess' to them. If I got XL they would probably be just as baggy but with a bigger waist.
