Owala FreeSip Insulated Stainless Steel Water Bottle, 24 oz

Owala says the lid is leak-proof and that the carry loop doubles as a lock when the lid is closed. For drinking, Owala describes holding the bottle upright and sipping through the built-in straw. The brand also states that the triple-layer vacuum insulation keeps drinks cold for 24 hours. Owala's description says one push opens the lid and one push locks it.

The 24 oz size measures 10.68 inches tall by 3.12 inches across according to Owala's product details. The carry loop flips up when you need it and tucks away when you do not. The wide opening is meant for cleaning and adding ice. Owala says this stainless steel model should not be used with hot, carbonated or perishable liquids, so plan on water or cold drinks. For care, the lid is top-rack dishwasher safe and the straw can go in the silverware bin, while Owala strongly recommends hand-washing the cup to keep its finish. OutdoorGearLab's testers found the two-opening internal straw difficult to clean in every spot. Owala's FAQ says the stainless steel bottles should never be microwaved, and that although the bottle is technically freezer safe it recommends putting a few ice cubes in instead. The FAQ also says the straws can be easily removed and put in the dishwasher's silverware bin. Owala's page describes the lid as designed to be quick and easy to disassemble with minimal hard-to-reach surfaces, a claim OutdoorGearLab's testers did not find true of the internal straw. The Owala FAQ states that all its bottles and tumblers are and always have been lead free, and says it has used lead-free solder from the very beginning. Owala's warranty page states a Limited Lifetime Warranty against defects in materials and workmanship for bottles, with accessories and soft goods covered by a one-year limited warranty.

A rail traveler or platform watcher who wants one insulated bottle that drinks two ways and closes with a lock, and who will accept a lid that takes some brush work to clean. Not the choice for hot drinks or carbonated drinks.
