The North Face Terra 65L Backpack Grey Green
Great backpacking entry/moderate level bag
Quality is what you expect from The North Face, brilliant and sturdy. Have already been testing it on the South West Coast trail and have been very happy with it, particularly with the weight distribution system.
While lacking the bells and whistles (though it does have an emergency whistle) of the higher end models, there is nothing you can fault with this bag, especially at this price point.
