A hot water bottle bag($160) that you can fill your bag with hot water and give you warmth in the winter. I like this idea, but the $160, a bit expensive.
"Warm up your wardrobe with this bag made from a reclaimed hot water bottle used during the 1960s by the "Bundeswehr" (Germany's Federal Defense Force). Tough and utilitarian, the body of this bag is made of recycled truck tarp, while the army water bottle serves as a flap. Features a clasp for closing, long adjustable strap and an interior pocket for a cellphone or small item. Handmade in Stuttgart, Germany." |
