Wotancraft is known for their vintage inspired bags, and their Canteener EDC Utility Sling Bag is a take on the classic military canteen pouch. This is all about light weight, easy access, and construction. Well made to last a lifetime, water resistant, and bigger than most personal sling bags, but smaller and lighter than a messenger bag. I use it on photo sessions to carry extra batteries, audio gear, an extra lens, or as that emergency airplane personal item. Check it out at: https://www.wotancraft.tw/product/bdb26-m-blackC
