18 Oz. Sienna Stainless Steel Bottle

The 18 oz. Sienna Stainless Steel Bottle combines a stainless steel outer and inner shell with double-wall insulation for hot or cold retention, a wide-mouth opening for easy filling, and a screw-on, spill-resistant flip-top lid that stays attached rather than coming loose in a bag. It's BPA-free and meets FDA requirements for food-contact materials, and hand washing is recommended to protect the insulation seal over repeated use. The flip-top lid style makes it a slightly more casual, grab-and-go option compared to bottles with a separate cap, which matters for recipients who want one-handed access on the move.
