Solid
Great product. Don’t normally bother writing reviews but just went over the bars and landed on what would have been my face if it hadn’t been for this helmet. Body pretty banged up but not a scratch on my face/head

Meh
I might get some backlash here, but I may be the only one that hates this helmet. Pros: -Lightweight -Breathable -assorted cheek pad sizes Cons: -No rear tension for a snugger fit -Chin strap is impossible with gloves on *prefer a quicker release like the Bell Quick Air chin strap -sizing is off, the med didnt feel secure on my dome and a small was too snug -i cant pull up my goggles for a quick breather, they flop right back into your face I wore this helmet once on a longer ride and was so ticked the whole time. I fumbled with my gloves every time i wanted to take it on and off for a breather. And i know its not just me because my friend has this helmet and its annoying with the chin strap and gloves. I didnt like how lose it felt, i had to have the chin strap basically choking me and even then i just didnt like the fit. If Smith adds a rear tension adjustor and an easier way chin strap i would love it. Just not for me. Lame.

I've owned Smith ski helmets, first Smith bike helmet.
Great fitting, great looking, confidence booster. I haven't taken a fall with the Mainline, but feel that it will keep me safe if that day comes.

A great replacement for my old full face
I use this helmet for work and it’s making wearing a full face in this heat bearable. Love the Matte Black look and the vents to keeps cool. The MIPS is great, but can sounds a little creaky when coming down rough stuff. Not very distracting though. Would still recommend it to anyone looking for a lightweight downhill helmet.

Great for fast downhill runs
1 year of use later.. The mainline is fantastic when it's either below 60f or you are getting lots of air circulation on a fast downhill. As soon as your not moving fast enough on a day upwards of 75f you can't get this helmet off fast enough. The rattling issue is not an issue if you wear a sweat wicking cap under, which also improves general comfort. As far as crash protection, I took a huge spill bashing my noggin into rocks, the bike, and ground and the helmet held up amazing. It protected my skull from being split open and my face from being pulverized.

Wrecked it - shipped to ER with head trauma. I'm buying another one the next day.
I don't think I'd be sitting here easily ordering a new one today if I was wearing a different helmet yesterday. Absolutely solid piece of equipment, head injury could have been much worse if I was wearing something that sucked. Well done.

Best Helmets!
We love Smith! My wife and I love these helmets. We already have open face Smith helmets for MTB and Snowboarding and skiing helmets. These are so lightweight and comfortable. We both change our chin pads for optimal fit. Lots of vents for the hot days high in the Rocky Mountains of Colorado.
