Iron Flask Water Bottle

Yes, thanks to the double-wall vacuum insulation, it is designed to maintain cold temperatures for up to 24 hours. Performance can vary slightly depending on the ambient temperature and how often you open the lid, but it is highly effective for all-day use.

Yes, the bottle comes with a spout lid, a straw lid, and a stainless steel lid. You can swap them out depending on your activity—for example, using the straw lid for easy sipping during a workout or the stainless steel lid for a completely sealed, leak-proof experience while traveling.

Absolutely. The 18/8 food-grade stainless steel construction is safe for hot liquids and will keep them hot for up to 12 hours. Just be careful when drinking directly from the spout or straw with very hot liquids.

At 3.5 inches in diameter, this bottle is on the wider side. While it fits many larger vehicle cup holders, it may be too wide for some standard-sized sedan or compact car cup holders.

To preserve the vacuum insulation and the exterior finish, we recommend hand washing the bottle with warm, soapy water. While the lids are generally top-rack dishwasher safe, hand washing the bottle itself will ensure it lasts much longer.

No. The double-wall vacuum insulation prevents condensation from forming on the exterior, so you won't have to worry about water rings on your desk or moisture inside your gym bag.
