I bought a pair of Knockarounds because I wanted inexpensive sunglasses to take on my John Muir Trail thru-hike. I have an unfortunate history of stepping on or otherwise smashing sunglasses while backpacking and hiking, so I avoid expensive brands. I usually just purchase them at Target, but I decided on Knockarounds this time because I wanted polarized lenses.

The Knockaround sunglasses may look and feel cheap. They're extremely lightweight plastic. But so far, they've seemed to be pretty durable. I've taken them on some training hikes and roughed them up a bit, but mine haven't broken or shown any wear. The polarization works as advertised (you can tell by holding the lenses perpendicular to other polarized lenses, which then completely blocks out light). The only slight complaint I have is that these sunglasses do not well fit someone with a low nose bridge. I'll be purchasing some adhesive nose pads to rectify that issue though.
