The best way to pack your hunting daypack is to keep in mind exactly where each item is, and exactly how and when it will be necessary to access that item. For instance, things like your rangefinder, survival knife, or GPS unit might need to be accessed quickly and easily, so store these items in easy-access pockets, perhaps the ones you can access while you are still wearing the pack.
Another thing to consider is how loud the pack might become if you are digging through it for an item while your target animal is close-by. For instance, digging for that rangefinder might cause enough noise to scare the animal off completely, so keep it where you can get to it.
When using a built-in rifle sling like the ones featured in many of the packs that we looked at, it is a good idea to familiarize yourself with how the sling carry system works before taking it out into the field. They can be more complicated than they look, and it’s best to have it all figured out in the safety and light of your yard instead of a dark forest.
