double wall stainless steel

Most options are made from stainless steel. Some listings pair stainless steel with aluminum or include plastic lid parts such as polypropylene and silicone. One listing also notes 90% recycled stainless steel.

Care varies by model: many recommend hand washing the bottle body while lids or parts are top‑rack dishwasher‑safe; some items are listed as dishwasher‑safe overall. Manufacturers commonly advise not to microwave insulated drinkware.

Some listings are labeled for cold beverages only, others explicitly state they’re suitable for hot and cold drinks. At least one listing specifically notes it should not be used with hot liquids.

Many bottles include leakproof or leak‑resistant lids, locking or push‑button closures, and proprietary no‑spill straw systems designed to reduce leaks and spills.

Common features include double handles, small straw or sippy lids, splash‑ or leak‑resistant straw systems, dishwasher‑safe parts, and BPA‑free materials. One listing also notes a heavy‑duty double‑walled design using recycled stainless steel.
