As you probably know, there is a scare about the BPA (bioethsphenol-A) which leeches from many of the traditional sports water bottles which have been on the market, particularly the old Nalgene polycarbonate style. This has made stainless steel water bottles one of the hottest items in the promotional products market. From a promotional perspective, I think of them as comparable to an apparel item, but better—they are almost infinitely reusable, giving your message long term exposure. When/if they are finally discarded, they are 100% recyclable. The stainless steel ones, unlike the aluminum which are also available, don’t add a funny taste to the water. A color coordinated caribiner is a nice added touch, making it easy to attach to a belt or purse. Over the last several months, it has been hard to keep stainless bottles in inventory, so there could be long lead times. If you need them quickly, it’s worthwhile to check inventory with your supplier before ordering.
