ROCKBROS Customized High-Capacity Hot Cold Insulated Sports Water Bottle 304 Stainless Steel Inner Liner Water Bottle

Your Drink FStays Exactly For 12hr-24hr

Most bottles lose their edge within a couple hours. This one doesn't. The multi-layer stainless steel and vacuum insulation are built to hold a real temperature difference against the outside world, all day.

  • 12-Hour Heat Retention

    Your coffee or tea is still drinkable hot by the time your afternoon meeting rolls around. No microwave required.

  • 24-Hour Cold Retention

    Ice you add in the morning is often still there at bedtime, so your water actually stays cold through a full workday or a full hike.

  • Food-Grade Steel Liner

    What touches your mouth and your drink is the same steel used in commercial kitchens, so there's nothing plastic leaching into your water over time.

Built For The Way You Actually Drink Water

Twist off the lid, fill through the 5.4cm wide mouth, and twist it back shut. That wider opening means you can drop ice cubes in without wrestling them through a narrow neck, and it makes reaching in with a brush for a real clean just as easy

Feedback to the Bottles

Most of the feedback we get isn't about the bottle itself, it's about the habits it changes. Once people stop losing the temperature battle, they use the bottle more, and that adds up fast.

Frequently Asked Questions

FAQ

Is this bottle actually leakproof?

Yes, the lid seals fully shut with a locking mechanism, so it's safe to toss in a bag or lay on its side without worrying about leaks.

Does it work for both hot and cold drinks?

Yes. The same vacuum insulation that keeps cold drinks cold is what keeps hot drinks hot, so you can switch between coffee and ice water freely.

Will it fit in a standard cup holder?

Most car cup holders fit it comfortably, but if you're using an especially narrow holder, it's worth checking the bottle's diameter first.

Will the outer coating chip or peel?

The matte finish sits over the stainless steel outer layer and handles daily use well, though like any painted finish it's best to avoid dragging it across rough surfaces.

How do I clean the inside properly?

The 5.4cm wide mouth is sized so a standard bottle brush can reach the bottom. A quick scrub with soap and water after use keeps it fresh.

Is it dishwasher safe?

Hand washing is recommended to protect the insulation seal and exterior finish long-term. A quick rinse and brush takes less than a minute anyway.
