For the hunter who needs a descent amount of room but doesn't want to haul meat inside the pack, the overload alpha is ideal. The 4200 cubic inch bag with a load carrying feature makes this the optimal bag for those doing 5-7 day backcountry hunts. Instead of a traditional day pack lid, we incorporated a sealed flap that keeps the bag drier during rain showers. The daypack lid can be purchased as an accessory if extra space is needed. The Overload Alpha is a pack that will keep all of your gear clean and dry even after you've hauled out your fresh kill.
