I agree with Overbo--too loud. After this last season I changed my whole philosophy on packs. A few years ago I switched from the big Kifaru to the Eberle 105 because it was more quiet. But I was still having noise problems. This year I even dropped down to a smaller Cabela's day pack that did improve the limb-slap problem because of its lower profile but I found another problem--the shoulder straps, on packs in general, are made of synthetic material that causes enough noise when arms are raised, to alert game.
I verified this over and over this year with, especially, deer, but I had an elk at 15 yds that alerted when I simply brought my bow up. He got away and it made me look hard at this friction noise caused by shoulder straps.
Also, on most packs that have quiet-cloth material, there are other straps, cordura, etc., on the pack itself that make noise when contacted.
So I switched to a shoulder-type bag. I found the biggest one I could find that was not synthetic. I loaded it with essential gear and carried it around for awhile and found it was comfortable, much quicker to put on/off, and much more quiet. The bag itself rides lower and flatter against my body so will be better when ducking brush. I am adding belt loops on the bag so a waist belt can be used to better hold the bag against me.
With the other packs that I used I had the added advantage of being able to haul meat out, using the pack, on that first trip back to camp after a kill, and that is nice. But after this season and other, past frustrated experiences, I realized that my first priority is now to just get an animal down.
