IRON °FLASK 128 oz One Gallon Vacuum Insulated Sports Water Bottle
A high-capacity vacuum-insulated stainless steel water bottle designed for maintaining beverage temperature over long periods.
This product is a large-capacity sports water bottle, specifically designed to hold 128 ounces (one gallon) of liquid. Constructed from double-walled, vacuum-insulated stainless steel, it functions as a thermal mug or canteen jug intended for both hot and cold beverages. The design features two distinct lids: one equipped with a straw for easy sipping and another featuring a spout for pouring or direct drinking. Because it is marketed as leak-proof, it may suit users who need to transport large volumes of water during outdoor activities, sports, or long work shifts. When evaluating this item, buyers should compare the weight of the empty vessel against its total capacity, the durability of the stainless steel finish, and the specific flow rate of the included straw versus the spout lid.
