I recently upgraded my daypack. I had been using an old Cabela's fleece pack for a long time and it is trashed, so I did a lot of research, and decided on a Stone Glacier Approach. The one thing I was surprised by where all of the best quality packs were concerned was the lack of any very quiet material used in the bags. I think the Stone Glacier material is not all that noisy, but most of my deer hunting is for whitetails in the timber where a lot of times a 20 yd shot is more likely than not. So I started to think about a fleece cover, and again I was surprised to see that there are almost none to be had! I found one that they wanted $90 for and was not impressed, so I just made one. I'm gonna give it a try tomorrow and see how it goes. It's pretty basic.
