ESS CDI Max Sunglasses with Interchangeable Lenses - Polarized UV Protection for Cycling, Running & Outdoor Sports - Tourrain Tan Frame

I ordered these from the US and had them shipped directly to my location in Afghanistan to accompany my deployment. Shipping was fast, they made it here before I did. Overall quality is excellent, and I ordered replacement lenses in amber and copper. The copper color goes great for those not so bright days and you can see indoors also (had to order from another site, could not find on amazon). Anyway, quality is great and I'll do a pro/con like everyone likes.These are low profile as stated, but I found that while wearing body armor in a standing position (you know how you have to tweak your head just right to get around your kevlar collar) my optic sight on my rifle was not visible. It seems that I look right over the bridge of my nose, placing my tip of nose on the charging handle of the M4, the nose bridge of these glasses blocked view of the sight. So I went back to my issued ESS that have the lense that wrapps around.Pros:1. solid construction and quality2. ability to change lenses by simply colapsing the glasses and sliding the lense out3. the replacement lenses come in a small carrying case, you could easily fit them in your pocket or and empty pouch on the body armor.4. come with a case and headband.Cons:1. Limited field of vision (see remarks above)Overall these are great shades that fit in your pocket easily and can be used for a wide variety of projects and circumstanses. I have super long eyelashes that the ladies are crazy about, but they dont get in the way with these. I still wear my issued glasses for shooting in body armor because of the listed problems.
