Rated 4 out of 5 by from Great shades, Amazing lenses, but had durability issues Chromapop lenses are amazing, the brown lenses in my experience really do make colors much more vivid. Glasses have been great on fishing trips, tooling around on my SUP, on hikes or just hanging out around town. Only problem I have had is that after less than a year the inside of the lenses had appeared to have started to ripple, and wave. That being said I sent my glasses back to Smith and they were promptly replaced with a brand new pair 100% covered by the warranty. Wish there was an explanation for why that happened so I can try and make sure it doesn't happen again. Would be a solid 5/5 if it wasn't for the durability hick-up.

Rated 5 out of 5 by from Best Lens I've ever used I've tried the best lens's from Costa, Maui Jim, and Ray-Ban. These glasses in chromapop are the best variation of the "top dog" glasses on the market. I work at a marina in the summer and wear these every day. After work they work great whether I'm fishing saltwater or fresh. I wear these skiing in the winter as well. No downside to these glasses. I love how lightweight they are for the quality. Second place for me is the Costa Del Mar 508 Glass lens in terms of quality, but they are so heavy, therefor the Chromopop lens system is the best available. I have been wearing these for 2 years now and they still amaze me when I look at a body of water.

Rated 5 out of 5 by from "The Grass Really Is Greener" Ever heard the saying "The grass is always greener on the other side"? Well these Chromapop Lowdowns really are!!! No, literally, the grass and everything else you look at has such vibrant and beautiful color, it's almost unreal. The clarity is incredible. I had been waiting to get my hands on these for about 2 months since they were out of stock. Now I finally have them, and I can see what all the talk is about. The quality is spot on and I love the rubber panels on the nose and ears to help prevent them from slipping off your face. I could see the rubber wearing or splitting over time but so far so good! Seems pretty durable for the most part. The fit is perfect - I'd say I have a Medium sized face and these are an awesome fit. Overall, these are hands-down the best pair of sunglasses I have ever invested in and I am glad I waited. No complaints, even if I tried.

Rated 5 out of 5 by from Pop! Just picked up these in the Chromapop Polarized Gray Green and I can't tell you how much I love them. These lenses are unlike any other polarized lense I've tried where the clarity and the rich tones are truly worth every penny. The amount of coverage is perfect for me but I do enjoy a larger coverage, which is why I don't understand why Smith describes the Lowdown's coverage as medium. In my opinion they're a large to medium fit but I do have a smaller face. The nose and temple pads assure me these will not fall off my face even if I'm going on a hike or even taking a run. Sometimes I don't even realize I'm wearing them. The fit/style feels super solid and Smith did an excellent job on these glasses. I will defiantly grab a few more Lowdown's in different lenses in the near future because I just enjoy how they look. The rich tones, clarity and colors that these lenses bring out even on a slightly overcast day is amazing. If you have the money, don't even consider purchasing anything else because the Chromapop lenses will not disappoint.

Rated 5 out of 5 by from Great glasses! Being a sunglasses "collector", I have owned every type, brand, and manufacturer. With a retail sunglasses dealer in my family, it has allowed me access to even more, and when they asked me go with Smith Optics, I gave them a shot. The Lowdown matte black with red lens catch the attention of more people than my higher end glasses. These glasses are durable and lightweight. I am actually considering selling most of my sunglasses collection, so I can fill my variety of "shades" with Smith.

Rated 5 out of 5 by from Quality Sunglasses that Don't Kill Your Wallet I have been buying cheap Wayfarer style sunglasses for years, but finally I decided to drop some money on some decent quality glasses after breaking the cheapos on a regular basis. I was excited to find a pair under $100 when I stumbled upon the Lowdowns. They fit perfect on my medium face are still very light compared to some other quality sunglasses. I love the rubber on the back of the earpieces which keeps them on your face better if you are an active person like myself.

Rated 4 out of 5 by from Comfortable, great quality, but doesn't fit well on my face. Without trying them on I bought online because they looked very stylish. They are good looking , however they sit on my face fairly high. I feel I have a medium face (width and height) with medium height nose and the width on these are fine, just not how high they fit. The tops of the glasses go just above my eyebrows making them look odd on my face. I got the black w/ polarized grey lens and the quality and clarity seem very good. Comfortable and lightweight also. I'd recommend these, but just make sure to try on.

Rated 5 out of 5 by from Chromapop Lowdowns - the best! I've been wearing these glasses daily for over a year now. Snowboarding, bike riding, hiking - they always stay in place. They look great and the chromapop is really nice. I had an issue with the coating peeling off but Smith's lifetime warranty program and awesome customer service took care of that for me. Best sunglasses I've ever owned!
