This 64oz outdoor insulated vacuum flask is designed with double-wall insulation to keep your beverages ice-cold for up to 24 hours or steaming hot for up to 12 hours, making it perfect for all-day sports and outdoor adventures.

Yes, the flask features a secure, leak-proof lid design that ensures no spills or leaks, even when carried in a backpack or during vigorous outdoor sports activities.

The flask is constructed from premium, food-grade stainless steel that is BPA-free, rust-resistant, and does not retain or transfer flavors, ensuring a clean taste every time.

While it offers a large 64oz capacity to keep you hydrated all day, it is designed with a portable handle or carrying loop, making it convenient to carry for hiking, camping, and gym workouts.

We recommend hand washing the flask with warm water and mild soap using a bottle brush. Avoid using abrasive cleaners or putting it in the dishwasher to preserve the vacuum insulation performance.
