Attack MAG MAX

I use these for mountain biking and back country ski touring and they are the best glasses I have ever had for the job. They evacuate heat really well. They only fog up if you find your self stopping and panting breath up towards the lens. Even then, they clear up relatively quickly. They integrate with my Smith helmet with ease for those early morning ascents or for those times where you don't quite beat sunset. One complaint, the case they come with requires you to remove the lens for storage. The inside foam should definitely accommodate the glasses folded with the most commonly used lens. Five stars for the glasses. Minus one for the case. Freakin great product!!

Excellent for riding in the rain- raindrops bead up, and no fogging- the safest I've felt racing in the rain ever, and enough to make me a convert to these glasses. I haven't had issues with lenses breaking but I've only worn them for about four months. I thought the chromapop reflection glare that I noticed while trying them on would bother me, but with a helmet I don't notice at all.

Light weight and roomy. These glasses have great optics.

I've had these glasses for 15 months and have used them primarily for cycling but also for backcountry ski touring and running. Smith is a hometown company for me, and I want to love these glasses, but they need to overcome a significant design vulnerability.



Pros:

- The lens quality is amazing. I love the ChromaPop technology and really appreciate that the second lens is a rose tint and not just a clear lens. The green is excellent for bright days, and the contrast is great.



- MAG interchangeable lenses. This is the easiest lens changing system I've ever used personally. I know there are others that are arguably as easy, but this is just so smooth.



Cons:

- MAG interchangeable lenses. The simplicity of changing lenses comes at a cost. It's a beautiful design on paper, but it doesn't stand up to real-world conditions. The plastic anchors on the corners of the lenses, where the arms clip into, are attached to the lens very delicately. In the 15 months I've owned the glasses, I've had two lenses break. Both times the break was from opening the arm of the glasses with a light touch. Underneath the anchor, the lens is only held together by a few small pieces of lens plastic. This is a critical point of failure that gets a lot of repetitions of low pressure force (i.e. hinging the arms open and shut). In addition, the magnets are good, but not great. I repeatedly had an issue there the magnets wouldn't stay clasped together, and closing the arm would cause the magnet to unclasp and the arm to fall off. I also had a magnet rust. And then the lens was damaged by rust.



I wish these were more robust, but I can't keep using them because I want to use gear that I know will stand up in the field. I don't want to take backup glasses on a ride, or on a multi-day bikepacking or ski touring trip. Until the Smith MAG system is updated, I'd have to shy away from anything using that system.
