It’s like finding a wife - keep your standards high as possible and it will work out better in the long run, even if the first model you bring home doesn’t stick.
What are you looking for in a pack? Day hunt, hunt from truck, backpack into an area, etc… lots of questions to answer before suggesting any type, style, or brand of pack.
Second most important is a pack. Choose wisely and don't skimp. Fit is very personal so you may want to order a few and try them all.
I'm a Stone Glacier fan. The X curve fits me great and I like the simplicity of their packs. I use a 5900. Good for multi day trips. Good for an afternoon hunt because it scrunches down to nothing.
