TrailBottle Stainless Steel is an extremely durable water bottle in high quality stainless 18/8 steel for those who are on the go. Stainless steel neither picks up nor gives off flavours. The lid is made of plastic and contains no BPA. The water bottle has a large opening which makes it easy to fill and clean. With a strap connecting the cap and the lid, you can be sure that you will not drop and lose the cap. You can also attach the loop on the strap to your backpack so that you always have water nearby during a long hike, when training or taking a walk to work. The bottle has a standard thread to fit most water purifiers and filters on the market.
