I just got a new one to replace the one I've worn for several years. It is great for moderately active days like rock climbing, but not great for high output. Perfect for multi day adventures as it does not hold odors as much. Fit chart is accurate but expect it is a performance fit. Store it with some cedar shims so the moths don't get to it.
