REI Flash 65 Men's Large Internal Frame Backpack. I bought this in 2010 or 2011 (not sure) and used it for a total of five nights in the Superstition Mountains. While climbing Battleship Mountain, I butt-scooched a narrow ridge and wore a small, 1" diameter hole in the bottom. It is patched from both sides, inside and outside. Otherwise the pack is in excellent condition.
Asking $70 shipped from Alaska. Please contact me via email: [email protected]
