I picked it up for my daily run in non-summer season. So far they work really great. The back mesh helps breeze, and not so obvious reflective signs actually work nicely. I got nighthawk color, which is cool combination of blue and gray. I still love the color but also wish Arc would offer it in much lighter gray, as the color isn't the best in sunny day. I also love the pocket design, I hated Accelereo due to tiny useless pocket, but Incendo really nailed it.
