I'm planning my first trip to Colorado for an OTC archery elk hunt. We plan to backpack in fairly deep and hunt for 7 days. I have a Badlands 4500 and have heard most guys saying not to use their hydration bladder in the lid of the pack.

So I'm looking at some other bladder options to put either inside the main pack or in the vertical pockets on the side of the pack. How many ounces of water do you think I need to pack most of the time? I will be packing a water filter and hope to have decent access to water but not sure yet.

Trying to understand if a 70 ounce bladder is enough water to carry most of the time or if I need a larger bladder. Thanks in advance for your help. I'm sure I will have other questions along the way, I'm consumed by it already and it is only May
