I have a like-new (worn for 2 hours) Patagonia Chest Pack that I will sell for $40. It originally retailed for $129 and the street price is about $65. I basically didn’t the chest pack concept and went back to my ancient vest. Traditions die hard.
I holds a lot of gear. The back section will hold a rain jacket and your water. Patagonia has even engineered in opening and holders for the tube so you can drink while you fish!
Rather than posting pictures, here is the link to the Patagonia site:
