The wide handle and non‑slip finish make it easy to carry and use on the move.

How long will beverages stay cold or hot in this 128oz bottle?

The WATERSY gallon jug uses vacuum double‑wall insulation plus a honeycomb thermal layer in the lid to slow temperature transfer. In normal conditions it maintains cold for up to 48 hours and keeps hot liquids warm for as long as about 24 hours, depending on initial temperature and ambient conditions.

• Double‑wall vacuum insulation with copper lining for improved thermal retention
• Honeycomb thermal layer in the lid reduces heat exchange
• Keeps cold up to 48 hours, hot up to 24 hours under typical use
• Performance varies with climate, fill temperature, and opening frequency

Is this water jug truly leak‑proof and convenient to carry?

Yes—WATERSY engineered the spout cap with a silicone seal and advanced sealing tech to prevent leaks during transport. The bottle also features a wide, ergonomic handle and a sweat‑proof powder coat, making it comfortable to grip and carry even when filled to 128oz.

• Leak‑resistant spout cap with silicone ring for a secure seal
• Non‑slip powder coating for steady grip and dry exterior
• Wide molded handle designed for one‑hand carrying and pouring

What materials and safety features are used in this jug?

The bottle is constructed from food‑grade 18/8 stainless steel and includes a copper‑lined interior to reduce heat transfer and preserve beverage taste. It is BPA‑free and reusable, intended to avoid residue and retain the clean flavor of water and other drinks.

How do I care for and clean the WATERSY 1 gallon bottle?

Routine cleaning keeps the bottle performing and tasting fresh. Hand wash is recommended for the lid and spout; the stainless interior can be rinsed with warm, soapy water and allowed to air dry. Avoid abrasive cleaners that could damage the exterior coating and insulation.

• Use warm water and mild detergent for the stainless interior
• Air dry fully before reassembling to prevent odors
• Do not use bleach or abrasive pads on powder coat or seals
