Gregory Whitney Backpack.
It's a few years old but I haven't used it in three years. It's in perfect shape. It's a medium with a small waistband.
This pack is comfy and probably close to 5000 cu. in. You could easily pack everything you need, including food, for ten days to two weeks into this pack.
This year's version of this pack costs $385 at REI right now.
$100.00 You pay shipping. I can take credit cards.
