James T.wrote a review of Smith Pivlock Arena Max ChromaPop Sunglasses on August 14, 2017
First, the lenses are high quality. Note that the category 3 lenses worked best in full sun, even with Chromapop. To echo a previous reviewer, the pivlock mechanism seemed destined to fail; after several months, it finally did. Not sure if it was just my pair as only one of the arms had this problem. Fortunately, Backcountry was there to help out. Thanks!
