Function meets style with this insulated water bottle. Produced from high-quality, highly durable materials, these versatile flasks are more than up to the challenge of keeping pace with the busy commuter, frequent gym-goer, or the dedicated hiker. Double-walled vacuum insulation preserves drinks, without affecting the outer temperature. Fill this drinks bottle with a generous cupful of hot tea, coffee or soup, and it will stay warm for up to 6 hours without burning your fingers. Iced tea, water, and other cold drinks remain refreshingly cool in this handy metal bottle, too. Looking as good as it performs, it sports a matte black exterior, while its tall sleek shape will slip easily into any bag or car holder.
