    SO Hydrated

    • Familiarity: I've put it through the wringer

    I bought this bottle to replace my 32oz Nalgene and have absolutely zero regrets, I carry it with me everywhere and never have to worry about being dehydrated (because that's something I worry about constantly.) It's also rugged enough to be thrown around the trails and camp. My hydroflask has also kept water cold for 10+ hours in a hot car in summer, which just blew my whole mind. I will say that it's not the lightest water bottle there ever was , as its stainless steel and probably wouldn't carry it with me on longer hikes, rides or backpacking trips.

    Awesome water bottle for hot climates

      I’m from Maine where it’s generally not very hot. I’ve been visiting North Carolina where it’s been extremely hot lately. I like to go for walks that last an hour or more but after about 30 minutes my un-insulated bottle of water was getting too hot to be refreshing. Today I used my new Hydroflask 40oz water bottle and my water stayed cold for the whole time I was out in 90+ degree temperatures. When it’s this hot and humid it’s very important to stay hydrated. This fabulous water bottle will enable me to do that. I love the lilac color too.💜

      NO BRAINER

      • Familiarity: I've put it through the wringer

      I absolutely love this water bottle! I take it everywhere! It keeps my water cold all day and provides enough to keep me hydrated throughout the day.

      Icy cold

      • Familiarity: I've put it through the wringer

      Love this bottle size for having ice all day long, the wide top is super easy to fill too. The bottle can get a little heavy so I suggest a smaller size if you're hiking/backpacking.

      Nice and cold

      • Familiarity: I've used it several times

      Works as advertised. Water stays plenty cold. The bottle is a little heavy to hike/workout with but it's great for around the home and office. Large size keeps you well hydrated all day

      Hydro Flask Fan

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

      I gave this gift to my nephew as a gift and he absolutely loves it! He has always been a fan of Hydro Flasks and this one is just as amazing as he had imagined it would be. It keeps the ice and water cold for many hours and it is the best water container!

      Stay Hydrated Folks!

      • Familiarity: I've put it through the wringer

      I'm a firm believer that having a bottle of water on hand helps you to drink more water throughout your day. This bottle keeps my water cold all day and then some! It's certainly not light so, I wouldn't recommend using it for hiking or backpacking. A much better alternative to wasting plastic water bottles. My bottle has held up very well and is still keeping my water cold after a couple years.

      Fantastic purchase.

      • Familiarity: I've put it through the wringer

      I use this bottle every single day. It makes it easy to remember to stay hydrated on a day-to-day basis, even on busy days. Durable and can’t wait to use it on hikes this summer.

      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.
