In the familiar Hydro Flask quality, the 40 oz Wide Mouth Flexi Cap keeps 1180 ml of warm drinks warm longer and cold drinks cold longer. In numbers: cold beverages stay wonderfully refreshing for 24 hours; you can enjoy hot coffee or tea for up to 12 hours. The wide opening makes it easier to fill your bottle without spilling. The foldable carry handle simplifies handling. The craftsmanship is consistently excellent. Thanks to the powder coating, the insulated bottle retains its color permanently; the 18/8 stainless steel is, of course, BPA-free, very durable, completely flavor-neutral, and highly hygienic.
