Stainless Steel Outdoor Thermos Cup (1700ml)

Designed for outdoor enthusiasts and everyday heavy use, this 1700ml vacuum thermos bottle combines durability, functionality, and smart design.

The bottle is made from high-grade 316 stainless steel, known for superior corrosion resistance and excellent thermal insulation. Whether you prefer hot tea, coffee, or cold water, the double-wall vacuum insulation maintains temperature for extended periods.

A key feature is the integrated tea separation filter, allowing you to brew loose-leaf tea directly inside the bottle without residue. The lengthened and widened stainless steel filter net ensures clean separation between tea leaves and water.

The one-button opening lid enables quick, one-handed operation — ideal while hiking, driving, or working. A solid side handle provides secure grip, while the military-inspired army green finish adds a rugged outdoor aesthetic.

With its large 1700ml capacity, this thermos is perfect for long trips, camping, fishing, construction sites, or daily hydration without constant refilling.
