The Tracks from Sundog represent a good value choice with split interchangeable lenses (three supplied) and a sturdy case and bag for storage. The finish, however, is befitting of the low price, leading to a certain amount of distrust with regards to any rough usage.
They don’t provide a particularly positive feel on the face and while they didn’t actually fall off during the tests, such an event never felt far away. Similarly, each time we decided to switch the lenses we became concerned how easily they dropped out with only the lightest of touches.
From a purely biking point of view they are, however, comfortable and provide good visual acuity. The only problem here is the slight peripheral obstruction from the chunky nosebridge and side arm hinges.
