The Klean Kanteen Classic Narrow Sports Cap is the perfect drinking bottle to take with you during hikes, while exercising or simply for daily use. It comes with the Sport Cap made from soft silicone. It is dishwasher safe, can be opened with one hand and comes with a practical loop so you can attach the bottle to your bag. This Narrow version is a bit narrower than the standard Klean Kanteen Classic, so it fits more easily in the side pocket of your bag or in the cup holder of your car. And it still holds a good 500 ml!
