Exped Summit Hike 25 Litre pack with phone and hydroflask carrier options on the shoulder straps and a quick attach ice axe attachment on the external daisy chain.  The pack's main compartment is easily accessed with a wide opening zipper closure and a small zippered "brain" compartment on the top.  The two mesh size exterior compartments hold a guidebook or waterbottle.  The pack is great for mountain adventures or around town.  It's had minimal use and is in excellent condition.
