The klim nap pac is a quality pack at a reasonable price. Its a tad smaller than a lot of them, but works well and has an insulated mouth piece for the bladder. Not sure why you would want to wear one if your not riding out west, or are you? I find them to be bulky and restrictive but wear it out of necessity. I need my life safety gear,shovel and probe on my body incase of being seperated from sled in an avalanch. The only reason I wear it in the U.P. is because its already packed. If I only rode the U.P. I would pack everything on the sled and carry less weight on my worn out back. Mine ways in at 14 pounds fully loaded and it starts to get old by the end of the day. But, to each his own--eh? Also will add be sure to get one with a waist buckel AND a chest buckel. Makes a huge difference in comfort and keeping the pack from bouncing around!!
