The DRAGON RVX MAG OTG Goggle is a magnetic ski goggle for quick-lens changes on the mountain or in the lodge. The OTG means they're over-the-glasses compatible, delivering eye protection for glasses-wearers as well. The snow, wind, sun, and more can be harsh on your eyes, and if you're not seeing clearly, it can lead to some serious situations, whether skiing or snowboarding. Protect your eyes with this medium fit goggle that is also helmet compatible.
