Hello everyone. I'm trying to workout my clothing system for an upcoming rim to rim backpacking trip in the Grand Canyon. I don't have any of the windshirts you all have mentioned but I do have a cs95 windproof smock that I use at various times here in Cali. As it is kind of a go to piece of kit for me, I was planning on taking it for this trip. This thread has got me wondering now though if I should maybe get something else. Do you guys know how the cs95 compares to some of these newer windshirts? From what my friend who is masterminding the trip tells me, the temperature could range from the teens to the mid 50s with rain and/or snow.
