  • It looks like the top lid changed to add a carrying piece. Is it plastic? Is it durable?

    Asked by: Krisbri
    It is plastic and durable. It is covered under our lifetime warranty. It is the same cap as the wide mouth flex cap, but now for the standard flasks.

    Recently, concerns have arisen about insulated stainless steel drinking containers having high lead levels in the seal/plug/paint. I am looking for a safe option that is responsibly manufactured and 3rd party tested for lead, etc. Will your items work?

    Asked by: Dana2pups
    Since the company’s start in 2009, Hydro Flask products have always met the stringent safety standards set forth by the Consumer Product Safety Commission (CPSC). In late 2012, Hydro Flask made the decision to further improve our products, manufacturing practices, and the industry standard. We moved beyond the solder dot on the exterior bottom of select Classic Stainless finish flasks (it should be noted that because all of our flasks are double-wall vacuum insulated, the solder was never in contact with the flask contents) to a proprietary glass frit on all of our products, eliminating even the smallest amount of lead. As of August 2013, all Hydro Flask products are manufactured with this glass frit. And, as always, they’re all made from food-grade stainless steel, BPA-free materials, and carry a lifetime warranty.

    Does the sport cap  that is available on the standard mouth easy enough for a 2 year old to  manipulate?

    Asked by: Blackwaterotter

    Can the hydro flask float?

    Asked by: bcarlisle

    Would it be a good idea to paint on this waterbottle? I could show you a picture after I paint on it, I could send on any social medias.

    Asked by: Hydro Flask Bot

    is the spot cap lockable for putting it in a backpack. would it leak in a backpack?

    Asked by: thirsty1000

    If construction is made from "high quality" stainless steel, why is the interior coated with plastic as quality metals do not hold taste.
