I sprayed a good coating of "waterguard" on my old Columbia shell last night. We'll see if it helps. I had about a half of a can left and used it all on the jacket.
Where I live is at 7,000 feet. Where I hike is at 8,000 to 9 or 10 for now. (close by) Temperatures are generally cool enough to not sweat to death or warm enough to take the jacket off and tie it to the pack in the summer. As I mentioned, I found out my shell was no longer waterproof when it rained and then hailed on me about 3 weeks ago.
