Questions and answers

What sizes and lids does Iron Flask offer?

Iron Flask bottles run from small everyday sizes up to 64 oz, in wide-mouth and straw-lid versions. Many bottles ship with two or three lids, such as a straw lid, a flip lid and a handle lid, so one bottle covers gym, desk and trail use.

How long does an Iron Flask bottle keep drinks cold?

Iron Flask rates its double-wall vacuum-insulated bottles for roughly 24 hours cold and around 12 hours hot, depending on size and fill level. The 64 oz bottle holds cold drinks longest because of its volume.

Does Iron Flask have a warranty?

Iron Flask covers its bottles with a limited lifetime warranty against manufacturing defects such as insulation failure or a leaking seam. Normal wear, dents and lost lids are not covered, and claims go through the brand's support with proof of purchase.

Are Iron Flask bottles dishwasher safe?

The bottles themselves are hand wash only; the lids and straws are top-rack dishwasher safe. Hand washing the bottle protects the powder coat and the vacuum seal.

How does Iron Flask compare with other insulated bottle brands?

Iron Flask matches the insulation and 18/8 stainless steel of premium rivals and usually includes extra lids in the box. It is heavier and bulkier than slim bottles, and its powder coat can chip with rough handling.
