OGGI's Freestyle Stainless Steel Bottle is reliable, durable, and convenient for any activity you choose for it. Take it with you wherever you plan to roam! Throw it in your bag for a day at the beach, in the mountains, a hike in the woods, or a couple of hours in the gym. The double-wall stainless steel vacuum insulation keeps your beverage of choice at the temperature you desire. Hot drinks will stay hot for 12 hours and cold drinks cold for 24 hours. The wide mouth opening allows ice cubes to easily fit inside and the spill-proof screw top is key in avoiding any unwanted leakage. The bottles’ exterior finish is sweatproof and delivers a slip-resistant grip. To keep the exterior looking its best, hand washing top with soapy water is recommended. Both the 17oz and 23oz bottles are sized to conveniently fit into backpacks and car cupholders. The sleek simple design of the Freestyle bottles paired with the many beautifully curated color options will fit seamlessly into any lifestyle.
