Kerilyn Insulated Gallon Jug 128oz Stainless Steel — Dark Blue, Double-Vacuum Insulation & Wide Mouth

Kerilyn's Insulated Gallon Jug is a 128oz double-vacuum stainless steel water bottle with a wide mouth, molded handle and sweat-proof finish designed to keep drinks cold for up to 48 hours or hot for up to 24 hours.

Built for long outings, shared use, and active days, this one-gallon jug combines a high-capacity interior with rugged 18/8 stainless steel, a leak-resistant wide lid, and a powder-coated exterior. The design balances spill protection and easy refilling, making it useful for travel, workouts, camping, and everyday hydration. The dark blue finish resists scratches and the non-slip surface helps keep the bottle secure during transport.

How does the jug keep drinks cold or hot for so long?

The jug uses double-wall vacuum insulation and high-grade stainless steel to limit heat transfer. That vacuum barrier slows warming or cooling, so cold beverages stay icy and hot drinks hold heat significantly longer than single-wall containers.

• Double-wall vacuum keeps temperature stable for extended periods.
• 18/8 food-grade stainless steel resists corrosion and prevents metallic taste.
• Powder-coat exterior reduces sweating and improves grip.
• Tested performance aimed at maintaining cold up to 48 hours, hot up to 24 hours under typical conditions.

Is this gallon jug easy to carry and refill?

Yes — the jug has an integrated ergonomic handle and a four-inch wide mouth that makes pouring, adding ice, or filling from larger dispensers straightforward. The handle's placement and bottle balance reduce strain when transporting the full 128oz capacity.

• Molded handle designed for comfortable carrying, even when full.
• 4" wide mouth accepts large ice cubes and makes cleaning easier.
• Leak-resistant screw-top reduces spills while in transit or in a bag.
• Compact footprint for a one-gallon bottle fits many vehicle cup holders and backpacks with external straps.

What materials and safety features are included?

The jug is made from 18/8 food-grade stainless steel combined with BPA-free plastics in the lid and seal, ensuring a neutral taste and safe contact with beverages. The powder-coated finish is durable and helps prevent condensation, keeping bags and gear dry.

• 18/8 stainless steel interior for durability and flavor neutrality.
• BPA-free plastic components in the lid and gasket for safety.
• Powder-coat finish for sweat-proof performance and scratch resistance.
• Sturdy construction resists dents from everyday outdoor use.

How do I clean and maintain the jug?

The wide mouth allows straightforward hand-washing and access for bottle brushes; the lid and gasket detach for thorough rinsing. Regular cleaning after use prevents residue buildup and keeps seals performing correctly.

• Hand-wash recommended; disassemble lid and gasket for deeper cleaning.
• Use a soft brush for interior and a mild detergent to preserve finish.
• Rinse and air-dry fully before storing to avoid odors.
• Avoid bleach or abrasive cleaners to protect powder coat and seals.
