Why We Like The Shift MAG ChromaPop Sunglasses

There's nothing worse than squinting our way through a bike or a trail run, and we're set on making sure that doesn't happen by donning the Shift MAG ChromaPop Sunglasses. ChromaPop lenses make everything from wildflowers to the blues in the sky pop, and a comfortable fit means we'll be wearing these sunnies all day. While the lenses enhance natural color and contrast for optimal optics, we also like the large amount of coverage we get from a medium fit. Two-click position adjustable fit Megol nose pads and Megol temples offer a non-slip grip so everything stays in place, and the Smith MAG frame lets us swap out lenses easily as needed.

Fantastic fit, used it for a bike race

Familiarity:
I've used it several times

I bought the item for a bike race and it was amazing. Perfect fit and perfect for the sunny day out on the road. After 5hrs and the road, it was still comfortable and didn't have any irritations.

IMO not worth it

I use these for mtb biking and work. First week I had them they stayed nice and firm on my hat. After a week they started falling off my head. They fell once and got scratch up super easily. Not satisfied at all. Save your money.

Love - but fit could be better

I definitely have a small head, no doubt about about that. But they bounced around a lot and don't fit my temples and feel too flexy side to side and I can't keep them steady when riding really fast in chunky terrain

Not Impressed at All

Even though I purchased these at a steep discount, I will return them. They feel incredibly flimsy. I found the lenses hard to swap out. Even after I practiced and practiced I still found them difficult to change. When closing the arms of the sunglasses, the Smith logo on the side almost pops out on its own. I fear this would lead to an accidental release of the lenses. I couldn't change the lenses without getting fingerprints on both sets of lenses, which defeats the purpose of using these on multi-day bikepacking events. The clear lens already had a nick in it too. They also felt like they were going to slip right off my head. I couldn't take them out biking, because I already knew they wouldn't work for me. I like the shape of the lens, and they seem to provide good coverage. I know they would end up broke or scratched in about a month with how hard I am on gear. I'll keep looking for a pair of sunglasses with better fit, quality, and functionality because the Shift Mag lacks all of those features.

I really like the fit

I really like the fit of the Shift MAG, and am impressed with how light they feel. Good field of view, and top shelf optics. I do find it a bit of a task to line up the lense with the bottom edge of the frame, but overall, I would buy these glasses again and am very happy with them!

These are great glasses if

These are great glasses if you want light feeling glasses that don’t put much pressure on the bridge of your nose. The lens that adapts to light works great as well.

Kinda good but definitely not durable

They worked good until the magnetic mechanism that holds the lenses broke under light pressure in my pocket. Smiths quality has declined in recent years (I’ve noticed this with their helmets as well as sunglasses) and these sunnies are proof of that. Not related to these glasses, I had a horrendous experience with their customer support team over a separate order. So between these breaking on me and my horrible experience I wont be buying anything Smith ever again.
