That is what I mean't. Not too sure its silly, especially if the bigger pack's profile isn't conducive to hunting in the timber. I've never tried a Kifaru but can assure you some of the competitors aren't worth a shiite in day pack mode.
B, think of it this way. The limiting factor in how svelte the pack is when you're going through brush is the frame, not the bag. If you cinch down the compression straps with a partial load the pack will be as wide as the frame and as tall as the frame, but no less in either dimension.
So changing out the bags won't make a difference in how small you can make the pack, with a daypack-sized load aboard.
