    Rated 5 out of 5 by from Great product! Nice quality!! Bought 8 Hydroflask products for my adult children and their spouses as Christmas gifts. They all loved them . Paired the coffee flask with coffee pods, the water bottles with protein bars.... the options for gift giving are endless. Will be getting my 7 grandchildren Hydroflask products as soon as they have a sale on them !! Hopefully before summer as they would be great to take to the beach or pool!

    Rated 5 out of 5 by from Christmas Flask I love my hydro flask. I never thought I would have one of my very own. Now I can have ice cold water during practice, instead of a plastic bottle.... yay!

    Rated 5 out of 5 by from Love My White Skyline Bottle! I love my hydroflasks. No other water bottles even come close to keeping my water cold. I was so excited when I saw the Skyline collection. I like the unicolors. Wish there was a white boot to match.

    Rated 5 out of 5 by from Life proof! I have always loved hydroflask but the skyline series is gorgeous, functional and sturdy all in one! The loop is great for attaching to a bag or holding with other stuff in your hands too, I was originally a little worried about the white getting grimy or damaged easier but it’s been great on all my adventures so far!

    Rated 5 out of 5 by from in love with the color I bought this 1 month ago and I love it. Ive gotten many compliments. The only thing I suggest is having it in bigger sizes

  • Is the white hydro flask white and gold as pictured or white and silver?

    Asked by: CNeedsHelp
    The rim at the top is silver but the Hydro Man on the front is a gold color.

    What is the color of the hydroflask logo on the white bottle? One review mentions a hint of gold — is it gold or is it silver like the other bottles in the regular line?

    Asked by: Izzi
    We just ordered just opened it and it has no hint of gold more like a beige color.  Picture is misleading

    I'm wondering if the lids are all the same size and interchangeable between the sizes?

    Asked by: brenda1234
    Yes, the small caps are interchangeable with the smaller mouth bottles ( the ones less than 32oz ). Same goes with the wider caps for wide mouth bottles.
