The pack fits my IPad Pro 12.9 perfectly in the back pouch. The mesh pouch houses my charging cords and power bank. The main bucket fits my rain gear, my Hidden Woodsmen Roll Top Coffee Bag, which I use as my food bag. The Esbit folding stove, Esbit Coffee Maker, and a Hidden woodsmen Pocket Pouch "boo-boo" kit, and UCO mess kit.
