"Five days on the Colorado Trail with the Ridgeline 38. Thirty pounds on day one and my shoulders never complained."

"The shell lives in my daypack now. It packs smaller than my sandwich and kept me dry through a hailstorm on Mount Sanitas."
Dev P., Boulder, CO. Stormline Rain Shell
Trail run
"No bounce on the descent, and I can reach both flasks without slowing down. I ran 18 miles in it on Saturday."
