WATERSY's 1-gallon insulated water bottle is a 128oz stainless-steel jug built to keep drinks cold up to 48 hours, hot up to 24 hours, and to resist leaks and sweat during active use.

This single-container solution combines heavy-duty 18/8 stainless steel with a copper-lined, double-wall vacuum design and an engineered lid to extend temperature retention. It’s designed for people who need long-lasting hydration on hikes, at the gym, during travel, or working outdoors. The bottle’s large capacity reduces refill stops while the integrated handle and non-slip coating make carrying and pouring easier.

How long will this bottle keep my drink cold or hot?

The WATERSY 1-gallon jug uses vacuum insulation plus a copper-lined interior and a honeycomb-insulated lid to extend temperature hold. Expect cold beverages to remain chilled for up to 48 hours and hot drinks to stay warm for as long as 24 hours under typical conditions.

• Double-wall vacuum insulation minimizes heat transfer.
• Copper lining improves thermal retention and flavor neutrality.
• Honeycomb-insulated lid adds an extra thermal barrier.

Is this bottle durable and safe for everyday use?

Yes — the jug is crafted from 18/8 stainless steel and is BPA-free for safe, reusable hydration. The exterior has a sweat-proof, non-slip coating and a rubber base pad to reduce wear, while the wide-mouth opening simplifies filling, cleaning, and adding ice.
