I purchased the Sentinel Jacket and Sentinel nomex pants just before a 10 day trip to the 2011 Sturgis Rally. As luck would have it, we were in our rain gear before sunset on the first day of riding, and used it during at least 7 of the 10 days. It performed perfectly, even in sleet and heavy rain that caught us on the Needles highway. I especially liked the vented back pleat and zipper vents in the armpits. These kept me comfortable even during the warmer parts of the day. The hood feature is the best I've seen. It's a nylon stretch-type fabric that holds the waterproof collar up. Only the collar is waterproof. The fabric thats under the helmet seemed to be very breathable. After one trip the durability appears to be very good. I'll have to see how it holds up over the next few years.
