Osprey Exos 46 Backpack

I have had this for 3 years and found that it's hard to beat haveing 9 diferent packs I seem to use this one the most. The mesh suspension gives a lot of air behind your back. I cut all the extras off and have the large 46 pack down right at 2lbs and less with out the top I also love haveing the stretchy back area to put coat or tarp ect in . I only have one caution keep it 20 25 lbs and u cant beat it over 30 it becomes like a bungy cord . The best part it light tuff and has a frame .
