    Rated 5 out of 5 by from awesome! I received mine for Christmas about 7 months ago after putting it on my list and I love it! It keeps things cold for soooo long and is so easy to use and portable. My one concern with this product is that it is kind of expensive and not very accessible to many people :( However, props to hydro flask for making a great water bottle!

    Rated 5 out of 5 by from greta insulation bought it over a month ago, fourth of July weekend while grilling, i place flask next to grill area and in the sun. Went to grab it almost burned my hand, was extremely hot. so when I uncovered it realized that water still had ice in it. None of the ice melted water was very cold.

    Rated 5 out of 5 by from Great for 12 Hour Shifts I wanted a water bottle to carry around with me at work because I easily can get dehydrated being a nurse. It keeps my water fresh and cool. I’ve had no complaints thus far. I’m very happy with my purchase.

    Rated 5 out of 5 by from Lifesaver at the beach! I’ve been using Hydroflasks for about 6 months now and I couldn’t be happier with them! I have two diff sizes that I interchange (yellow and lavender) and I adore them. My favorite thing is bringing it to the beach bc if I put ice and water in it it’ll stay cold and refreshing THE WHOLE TIME. Nothing feels better than opening my Hydroflask at the beach & feeling that ice water touch my lips. 10/10 would recommend & they’re aesthetically pleasing as well. The only thing I’ve had issues w is my sports cap, as it makes a squeaky noise when I’m drinking from it.

    Rated 5 out of 5 by from Great for kids at school! I love this product because I have so many different sizes for all my kids and even me! My child in 5th grade was having problems with her old water bottle spilling everywhere and she id not like how her water was getting to warm. So I decided to get our family the Hydro Flasks. We loved to pick out our coolers and my teenager even put cool fun sifters on hers! this was a great investment for our family. Thanks so much!

    Rated 5 out of 5 by from adorable color I bought this as a surprise for my mom because she loves everything light pink. I was worried the flask would be more purple in person than in photos because it’s called “lilac”, but the color is true to pictures and is so pretty. It’s a blush pink with a hint of lilac. Perfect size and actually makes my mom drink water so it’s a win for me. I want a pink one for myself! Only downside: does not come with hydroflip top.

    Rated 5 out of 5 by from No more plastic water bottles! I really enjoy this product. Prior to this I tried to avoid the use of water bottles and invested in other bottles, that just weren't working for me. Ive used my hydro flask every day since I received it in the mail. Easy to wash, clean fresh water taste after ever wash/use regardless of what was in it before--milk, juice, tea etc.

    Hello :) The descr. says "keeps cold for 24hrs, hot for 12hrs," however product video says "hot for 6hrs." The lid shown in the video is also different, does lid type affect time for heat? Which lid comes standard with this 18oz? TY!

    Asked by: rel1speed
    The flasks will keep liquids hot for up to the 12 hours and cold for up to 24 hours. The flex cap this one comes with does better insulate because it completely connects to the flask with no openings.

    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.
