    Trusted, Cold, and durable!

    • Familiarity: I've put it through the wringer

    I aboslutely love this water bottle keeps my drinks cold for as long as I could desire. This bottle has taken abuse from camp trips, tossed around in the car, and bounced off rocks on a few river trips! 10/10 would reccommend for someone who only wants to buy a product once.

    Perfect

    • Familiarity: I've put it through the wringer

    I've been a huge nalgene guy for a few years (I have 6 of them) but I finally decided to pick up a Hydroflask, and man oh man is it great. It keeps your water cold for hours, even if it's sitting in the sun. Yeah, it's heavy, but that just means it also counts as an arm workout!
    What're you waiting for, just buy one and stay hydrated!

    can't live without it

    • Familiarity: I've put it through the wringer

    I lost my 40oz Hydro Flask a little while ago and, after a few months of using smaller water bottles I had laying around the house, I finally replaced it with another one. I just can't live without the 40oz anymore! It's the perfect size to keep you hydrated, and works like a charm. Once I left my tea in it on a dawn patrol ski tour in negative temps and it was still hot by the time we got back to the car. A true win in my book.

    So good I had to get two!

    • Familiarity: I've put it through the wringer

    I already have one of these in an older color and I use it all the time! it keeps water cool and tasting fresh. I picked up two more, one for my gym bag and one for my desk!

    Perfect for the Wildland Handcrews.

    • Familiarity: I gave it as a gift but have feedback to share

    2 of these pairs with 2 classic Nalgene water bottles and you get the comfort of having plenty of cold water without too much weight!

    One of the best

    • Familiarity: I gave it as a gift but have feedback to share

    I already own a 32oz Hydro Flask, I bought one in the lemon color for a friend they take it with them wherever they go. I've been told it's a great reminder to stay hydrated when you have such a large water bottle looking at you.

    The Perfect Big Bottle

    • Familiarity: I've put it through the wringer

    Hydro Flask really never disappoints, and this bottle is no exception. Perfect water bottle for long day hikes or camping trips. Keeps your cold liquids cold, and warm liquids warm, although I really only put cold water in mine.

    Great

    • Familiarity: I've used it several times

    Awesome bottle! The handle makes it really easy to carry around and keeps things nice and cold or hot for a long time! Purchased a separate lid with the straw to make it easier to drink out of and it works really good! Definitely worth it!

    Hydro Flask 40oz

    • Familiarity: I've used it once or twice and have initial impressions

    You can't go wrong with Hydro Flask. Needed to add the 40oz'er to our collection. The size is great for longer trips.

    Best Bottle Ever

      My hydroflask lasted me 3 years, hundreds of drops, even more memories, and the teeth of a very curious Golden Retriever. I've dropped mine off the top of climbing routes, run it over with golf carts, and everything in between. The only reason I'm replacing it is because I left it on the bumper of my truck and drove away. Here's to 3 more years!

      LOVE

      • Familiarity: I've put it through the wringer

      if you are concidering getting a hydro for you or anyone do it and i think this is the perfect size, basically imposible to fit in cup holders but its worth having the volume.

      You won't go back

      • Familiarity: I've put it through the wringer

      Initially, the price might scare most people away, but once you get one you'll never regret it or go back to a regular hydration source. Love mine so much that I outfitted the whole fam with one for christmas this year and they love them as well. Look no further for your hydration source whether on the trail, camping or just taking with you everywhere throughout the day.

      Hydroflasks are the Best!

      • Familiarity: I gave it as a gift but have feedback to share

      I gave this to my niece, as her second Hydroflask. She wanted a bigger one to carry more cold water to practice, or more hot chocolate to the mtn. Hydroflasks are the best!!

      Great Bottle!

      • Familiarity: I've used it several times

      Hydroflask never fails with making great insulated products. This 40oz bottle is massive and is great to bring around town or school or work so you don't forget to hydrate. Keeps the cold things cold and the hot things hot. The mint is a fun color! Definitely a struggle holding for small hands but oh well. Still a great product!
