I am going on a wilderness elk hunt in Idaho with an outfitter this year. This will be my first hunt out west and I am starting to purchase gear for the trip. We will be hunting from a base camp in the wilderness so am looking for a great day pack option to carry my daily gear with me. I like the SG Avail but am not 100% sure if that is a big enough pack for a big game hunt in Idaho in November. Any advice would be appreciated.
