I have some Prism Trails and some Prism Roads. When I am on my home trails, in and out of the Pacific Northwest jungle, the Trails are mostly perfect. This time of year, though, on a cloudy day, even the trails are sorta too dark in the trees. On a sunny day, the Roads are perfect for out of the woods and just ok in the woods. The Roads are excellent for road biking! The non polarized lens helps me see my computer. I sprung for some Oakley Transitions type lenses, they go dark in the sun, but going from a clear cut into the jungle is like the lights got turned off. They work pretty well for mowing the lawn though. I get them at a pretty big discount by the way. To summarize and answer the question, I wouldn’t wear the roads if your ride involves shady woods.
