Aer Day Pack2 X-PAC High Water Resistance/Durability Bag Although I've removed the tag, it's brand new and unused. I purchased it during a sale on ZOZOTOWN, but I'm selling it because I bought a new one. The color scheme is really cool. The regular price is 35,200 yen, so I think it's a great deal. The following is a product description: The Day Pack2 X-PAC is a daily backpack designed for the modern business person. It features a minimalist design, multiple pockets for smart organization of small items, and a structured, self-supporting body. X-Pac is a new material derived from yacht sails, developed by DIMENSION-POLYANT, the world's No. 1 share holder in sailcloth (yacht sails). It is a special material that excels in strength, lightness, and water resistance.
