Haven't riden them yet but they certainly are substantial.
Warmth and Repellent
I just purchased the G-Shield Leg Warmers, as well as the Arm Warmers, Very recently I had the opportunity to try them out in Seattle in some cooler, rainy conditions. Wonderfully repellent, as well as keeping me very warm while cycling on my gravel bike on the John Wayne Trail in 50 degree Fahrenheit temperatures. I very much recommend this product for those that live in cooler, rainy climes, such as Seattle, and would like to have the luxury of shedding the skin when the weather breaks.
