Considering that 1,500 plastic bottles are used and discarded every second in the U.S., switching to a reusable water bottle is simple good sense. Memobottle makes the prospect a bit more convenient, presenting a slimline, rectangular water bottle that slips easily into your bag. It comes in three sizes -- Letter, A4 and A5 -- and features clear, durable, dishwasher-friendly, and BPA-free Tritan construction. Holding between 750ml to 1.25L of water, the Memobottle is a clever balance of environmental responsibility and lifestyle convenience. Head over to the Kickstarter page for more info.
