Features:

• IMPORTANT NOTE: Know that when you receive this product at your door, there will be a transparent protective film covering the mirror. This is to make sure the mirror remains crystal clear & doesn't get scratched during shipment. Please take off this protective film before using the product!
• FAST & EASY INSTALLATION - Easily attaches to your helmet in less than 60 seconds using an ultra-strong velcro pad. Just line it up exactly where you want it, then lock in your preferred adjustment - and you’re done! Once locked, the mirror stays in position so you never have to worry about it vibrating during your rides. Mounts on both left side & right side with ease.
• PERFECT REARVIEW VISION - Crystal view flat mirror helps you accurately judge the distance of objects behind you much better than a curved or convex mirror. 360° of adjustment allows you to use your peripheral vision to accurately see everything behind, while maintaining a clear view of the road ahead. The shaft length places the mirror at a perfect distance in front of you so it stays steady even during bumpy rides.
• FEATHER LIGHT & STURDY - Even though it weighs just 12g; you’ll be pleasantly surprised by how sturdy this mirror is. The strong polymer & aluminum construction makes this cycling mirror a perfect combination of ultra-strength & feather weight.
• LIFETIME REPLACEMENT WARRANTY & 90 day no-questions-asked money back guarantee.
