I purchased this before the coronavirus pandemic and used it for a while, but I'm selling it because I haven't been using it as much. The size is S, and it comes with a harness and drink pocket. *This item was used for mountain climbing, so I have inspected it visually, but please understand that there may be minor scratches. Also, please ask any questions you may have before purchasing. #Discontinued #Rare #Mountaineering #Zack #Rucksack #Backpack #mountainlaureldesigns #Ultralight #Lightweight
