WATERSY Insulated Stainless Steel Water Bottle, Red, 40 oz, Leak-Proof Straw and Spout Lids, 48-Hour Cold

The WATERSY 40oz insulated water bottle is a heavy-duty stainless steel flask that keeps drinks cold up to 48 hours and hot up to 24 hours while offering leak-proof straw and spout lid options.

This 40-ounce WATERSY bottle combines vacuum insulation, scratch-resistant coating and multiple lids to give you long-lasting temperature control and everyday convenience. Made from 18/8 food-grade stainless steel with a copper-plated vacuum layer, it’s built to preserve flavor and resist odors. The bottle ships with extra accessories—two lids, two straws, cleaning brushes, a carry pouch, paracord handle and reusable stickers—so you can customize use for the gym, travel, hiking or daily commutes.

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

The triple-layer vacuum construction with a copper-plated interior is designed to minimize heat transfer and maintain beverage temperature. Expect iced drinks to stay cold for up to 48 hours and hot drinks to remain warm for up to 24 hours under typical conditions. Actual times vary with ambient temperature and how often you open the lid.

• 48-hour cold retention for iced beverages
• 24-hour hot retention for warm drinks
• Three-layer copper-plated vacuum barrier reduces flavor transfer
• Optimal performance when lids are closed between sips

What materials and finish are used, and are they safe?

The bottle body is crafted from 18/8 food-grade stainless steel to resist rust and prevent metallic aftertastes. The exterior has a textured powder coating that improves grip, resists scratches and extends the bottle’s visual life. All plastic parts are BPA-free for safer everyday use.

• 18/8 stainless steel interior for corrosion resistance
• Copper-plated vacuum layer for thermal performance
• Durable powder-coated exterior that’s scratch resistant
• BPA-free plastic lids and PP drinking straws

How does the lid system work and is it leak-proof?

WATERSY includes two lid options: a straw spout lid for easy sipping and a secondary lid for alternate use. Each spout lid contains a silicone loop seal that limits leaks and stops splashes when closed. The design keeps water accessible during activity without sacrificing security in a bag or backpack.

• Straw spout lid for hands-free sipping
• Silicone loop inside spout to reduce leaks
• Two lids included for flexibility between activities
• Comes with spare PP straws and two cleaning brushes

What extras come with the bottle and how can I personalize it?

WATERSY packs a practical accessory set so the bottle is ready for daily life or travel. You’ll receive a carrying pouch and paracord handle for easier transport, two reusable waterproof stickers for personalization, and cleaning brushes to keep the straw and lid sanitary.

• Carry pouch and paracord handle for portability
• Two reusable waterproof stickers for DIY personalization
• Two cleaning brushes to maintain hygiene
• Spare lids and straws included in the box

The WATERSY 40oz insulated bottle suits active people who need long-lasting temperature control and a durable, customizable flask—from outdoor enthusiasts and athletes to commuters and students. If you want a large-capacity bottle that resists odors, endures daily wear and gives you multiple lid choices for sipping or straw drinking, this model covers both performance and convenience without adding bulk.
