AER Tech Pack 2 Business Backpack Purchased about a year ago. I'm selling it to organize my belongings since I'm using a different backpack now. It's in good condition with no wear and tear. I used it for about 3 months. The Tech Pack 2 is designed to organize and protect tech gear. It features multiple compartments for smart organization and a structured body that allows the bag to stand on its own. It also does not have a sternum strap. All compartments are sealed with YKK® AquaGuard® zippers to protect gear from wind and rain. Retail price: ¥42,900 (tax included) Aer was founded in 2014 in the San Francisco Bay Area.
