I bought these glasses for a glacier trip in the Alaska Range because they were cheap, seemed hard to break and well the color was just a bonus. They worked way beyond my expectations and since that trip I use them for all activities in the sun (skiing, biking, ice-climbing and kayaking, etc). These glasses are hard to break which is perfect in a recreational setting where you don't want to worry about loosing your three hundred dollar shades or need to pack light and don't want to pack a hard case. Ultra light they protect your eyes from the sun without making everything look too dark. It is hard to find glacier-glasses that are as affordable and multi-functional as the Tensing.
These aren't small, stylish glasses, so don't expect that, but they completely protect your oh-so-fragile eyeballs from the sun, and provide exceptional field of view, so they're just about perfect for out on the glacier. And what a price compared to other glacier glasses!You might look a tad bit like you're wearing your grandma's driving glasses, but your eyes will be protected, and your pocketbook will be happy. What more can you ask for?!
