So, my 13 year old son drew a LE rifle elk tag and a cow moose this year and the wife drew a cow elk. Now the kid is only a couple inches taller than the wife but he'll be out growing the pack by next year. So, my thought is to buy my 5'1" wife a pack that the kid will use this year. The question is, which small frame packs can do double duty for a season or two? Cost is a factor so I'd like to stay under $400, preferably less with discounts.
