I'm new here as well, but have been hiking/backpacking for a little while. I just use an REI flash 22 for day hiking. I like side pockets for water bottles and snacks but other than that, I just need a dump bag with straps. It's just me and my dog and we do 7-10 miles every Saturday and Sunday. The State Park we hike is a series of loop trails, so we're never more than 2 miles from the car. However, I could get everything I need in it for 15 to 20 mile point to point hike as well. I probably wouldn't won't to carry more that 6-7 lbs in it for any length of time.
