    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.

    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.
