There are two main optic products that I consider very important in bow season. I've been using Vortex for many years and they have never failed me.
As many hunters have, I've been through many back packs over the years and my favorite has been the Tenzing Hangtime Lumbar Pack. It is light and small enough to make it easy to carry but holds everything I need.
This is mostly personal preference on brand and pattern. I have always been a fan of MossyOak Bottomland for any type of hunting.
My advice is to wear whatever makes you comfortable.
The more confident you are in your equipment, the better you will shoot.
