I would choose between 3 different ones.

First- The Cabelas All-Day Transporter Fanny Pack, because it is weatherproof, adjustable and decently priced at $80

Second- TheHybrid Hunter 2-in-1 Pack, because it is very versitle, can be switched from a back pack to a fanny pack and comes with a water bladder,and is $120

Third- The Guide Model Fanny Pack, because it is quite, with not coloect burs and comes with a bottle holder, and is $90
