Teton Dave wrote a review of Smith Forefront 2 MIPS Helmet on October 3, 2018
Familiarity: I've used it several times
I owned the original Smith Forefront and rode it for a couple of years, and loved it, until I crashed and had to replace it. Because I liked the original I purchased the Forefront 2 with MIPS.
The good: great styling, great color selection, MIPS, comfortable, stays put, all good. It does what a helmet should do. Protect your noggin while not calling attention to itself.
The gripe: this is big for me, but maybe not for you. When I ride I tend to get what I call "hot head" - no matter what helmet I wear. My face and head always gets hot and it causes most glasses I wear to fog up. For that reason, I often put my glasses on my helmet until I'm done climbing and need them. The original Forefront had the eyewear groove above the visor, which made it very easy to place my glasses in the groove while riding and with one hand. On the Forefront 2 they've moved that groove underneath the visor. So, to get the glasses onto the helmet you need to move the visor up, and insert the arms of your glasses just right so they go into the groove underneath the visor. I have taken this helmet on 1/2 dozen rides so far and I can't get to the point where I can do this operation one-handed. This means that I need to stop, and with both hands insert the glasses into the channel. This is really irritating to me because I don't like stopping just to put glasses on my helmet. I can't get over this and I'm now irritated that I spent all of this money on this helmet and a seemingly simple design change has changed the way I have to ride. They claim that the groove in the back of the helmet will also hold your eyewear. It might, but who puts their glasses on the back of their head while riding? The fit of the eyewear/groove is not tight and I'm concerned that my eyewear will fall off without me knowing it.
Apart from that gripe, it's a great helmet. But, if you're like me, and you don't like stopping just to put eyewear onto your helmet, I'd look for a helmet that makes that process easier.
