I'm look for advice on a hunting pack. I hunt northern Ontario the first week of November each year. The weather is anything and everything. Last year I bought the Sitka fanatic jacket and bibs. They are to warm to wear while walking into the stands usually anywhere from 3/8 to about3/4 of a mile. I generally sit all day so I need something big enough for a couple of sandwiches and drinks plus the Sitka gear. Any ideas of a pack that I can strap the jacket and bibs to the out side.
