RAYMYLO Insulated Water Bottle 40 oz — Triple-Wall Vacuum Stainless Steel, 36-Hour Cold & Leakproof

This large-capacity bottle blends heavy-duty insulation with outdoor-ready features for everyday hydration and adventure. Crafted from 18/8 food-grade stainless steel and finished with a no-sweat powder coat, it’s built to resist odors, stains and condensation while offering a wide mouth for ice and easy cleaning. Included accessories — a spout lid, straw lid with extra straw and brush, paracord handle, carrying pouch and cleaning brush — make the bottle ready for workouts, commutes and camping trips.

How long will it keep my drink cold or hot?

The triple-wall vacuum with copper plating minimizes temperature transfer so cold stays cold and warm stays warm for extended periods. Tested performance reports up to 36 hours of cold retention and about 18 hours for hot drinks under typical conditions.

• Triple-layer vacuum with copper plating for enhanced thermal performance
• Keeps cold beverages icy for up to 36 hours
• Maintains warm drinks for around 18 hours
• No external sweating thanks to powder-coated finish

Is the bottle truly leakproof for travel and backpacks?

Yes — the RAYMYLO bottle comes with two lid styles engineered for spill prevention. Both the spout and straw lids use rubber seal rings to block leaks, and the threaded closures tighten securely for bumpy rides or packed bags.

• Spout lid for direct sipping and controlled pours
• Straw lid with quick-sip convenience and an extra replacement straw
• Rubber sealing rings resist drips and pressure changes
• Carabiner-equipped paracord handle for hands-free carry

What materials and cleaning options does it offer?

Constructed from 18/8 stainless steel, the bottle is BPA-free and formulated to avoid metallic tastes or lingering odors. The wide mouth makes it simple to add ice, pour smoothies and scrub the interior with the included bottle brush or run parts through gentle dishwasher cycles as recommended.

• 18/8 food-grade, non-BPA stainless steel interior
• Wide mouth for ice, fruit and easier cleaning
• Powder coating that resists slips and surface wear
• Comes with a straw brush and bottle brush for deep cleaning

What extras come with the bottle and how do they help?

RAYMYLO includes a selection of practical accessories so you can customize the bottle for different uses — quick sips on the move, spill-free storage in a pack, or secure handling while hiking. The paracord handle adds both utility and a survival-style feature, while the carrying pouch protects the finish when stowed.

• Straw lid plus an extra straw and straw cleaning brush
• Spout lid for controlled hydration while exercising
• Hand-knit paracord handle with compass and carabiner for outdoor use
• Protective carrying pouch and bottle brush included
