Hello /out/ I'm seeking something perhaps you all could help me find. I am seeking a backpack. The pack I am seeking is roughly 22" long ( I have a 21" item ) and roughly 40L of storage space. It will have to be durable and long lasting. Waterproof would be a huge plus, but not a necessity. Comfortably is a huge factor, it must have a waist and chest strap as well as shoulder tightening straps ( I searched backpack specs but I am not sure what those are called specifically but if you know please feel free to inform me ) Here is a cool kitty video ( unrelated ) Thanks
