Hydro Flask Pack Size Chart
Available Sizes S / M M / L
Torso
Measurement		 18 - 19 in 19 - 22 in
43 - 48 cm 48 - 56 cm
Hip
Measurement		 22 – 46 in 26 – 46 in
56 – 117 cm 66 – 117 cm

  1. 1. Torso Measurement

    • A. Bring your chin to your chest and feel for the most prominent bony bump where the slope of your shoulders meets the back of your neck. This is your C7 vertebra, and the top of your torso measurement.

    • B. On each side of your body, feel for the top of your hip bones, just below the sides of your ribs. With fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This is the bottom of your torso measurement.

    • C. Stand up straight and have a friend with flexible measuring tape measure the distance between your C7 vertebra and the imaginary line between your thumbs. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

  2. 2. Hip Measurement

    While your torso measurement is the best indicator of your pack size, it’s still important to check your hip size when using a hipbelt. To find your hip measurement, wrap a flexible tape measure around the top of your hip bones, just below the sides of your ribs. This measurement is slightly higher than your waistline

Rated 5 out of 5 by from Keeps everything cold I love this ice pack, not only it keeps everything cold in my Hydro Flask lunchbox, it keeps my beverages cold in my cooler. I will definitely purchase more.

Rated 5 out of 5 by from Hydro Flask Ice Packs The Hydro Pack Ice Packs are a great source for keeping drinks cool and above drinking standards. We recently hiked a few miles and the ice packs prove to keep drinks in likely drinkable temperatures. I absolutely recommend the Hydro Flask Ice Pack for all your hiking and adventure needs.

Rated 5 out of 5 by from Durable, non-toxic,and keeps food cold for hours! This ice pack is very durable and made of high quality materials. I love that the filling is non-toxic, just in case it leaks; which is unlikely, but better to be safe than sorry. Unlike many others, it is also so easy to hold. This ice pack is great for a day out hiking or even to use for a child’s or adult lunchbox. It keeps food cold and fresh for a full day.

Rated 5 out of 5 by from Love em! I got two of these, and I gotta say, I love how they perfectly fit my lunch boxes. No more punctured wobble goop gel to deal with. The only thing I would change is...I wish they had filled the hard plastic with wobbly goop instead of water. The main reason is that when it thaws out a little, the ice pack becomes a little noisy. But that's only a very minor complaint. No one is going to be saying HEY KEEP YOUR ICE PACK QUIET! Over all, I love it, and I would buy more.

Rated 5 out of 5 by from Cold for hours This hydro flask ice pack is heavy duty! It stays cold for hours. I am a full time student so I’m at school all day which means I pack a lot of food with me. This ice pack is the only one I need. It’s big enough to go in a cooler and can also fit perfectly in a large lunch box. No need to worry about it leaking or defrosting because it lasts all day.

Rated 5 out of 5 by from It's Amazing This ice pack does what you would expect it to. It stays cold for a long time out of the freezer even when it's not used in it's specified container. We have used it to keep food/drinks cold on trips as well as on injured muscles that need cold.

Rated 5 out of 5 by from Very nice The Hydro Flask Ice Pack - Pacific is a great ice pack. It is sealed tight so you do not have to worry about leaking. It also is a nice flat shape that doesn't take up too much room in a cooler. It seems to stay cold for a long time. Overall it does what an ice pack should.

Rated 5 out of 5 by from great so far Have been using it for a few days now in one of my coolers and has worked great so far. i usually take a cooler with me when grocery shopping and i like the design of the coolerpack because of how thin it is.
Date published: 2019-10-02
Rated 5 out of 5 by from All about the shape! I love this little thing (not actually little, actually a great size). The shape of it is so convenient! You can easily slip a juice in the center & keep it cold. Fits into the bottom of a lunch box very easily since it’s not thick and in the way like many other ice packs are. It’s very thin and easy to work around! The design makes this so great!

Rated 5 out of 5 by from Good Ice Pack My husband uses this ice pack everyday in his lunch for work. It keeps his food nice and cold without taking up to much room in his lunch pack. I like how it fits nicely in the bottom of his lunch pack. He does not have to worry about it leaking all over his food. Overall, it is a great ice pack.

Rated 5 out of 5 by from Keeps things cold This pack does exactly what it is suppose to do, keep things cold. It seems to last about as good as any quality cold pack. A lot is determined by the amount of things you are trying to keep cold and the type of insulated bag you have them in. It’s rigid and seems well built. Overall a good cold pack.

Rated 5 out of 5 by from Great for bruises I really like this Ice Pack and it's very convenient to use around the house. The grip prevents your hand from slipping so you can hold the ice pack firmly up against the area that needs some ice. My son needed to ice a bruise and the ice pack was easy to use and hold up against his foot.

Rated 5 out of 5 by from Nice Ice Pack Nice ice pack perfect for the soft coolers? Easy to use! Just place in your freezer and the next day your ice pack is ready for use. The shape is designed with the soft cooler in mind. I recommend this product to anyone with the soft tote cooler.

Rated 5 out of 5 by from Convenient Ice Pack The HydroFlask Unbound Series Ice Pack is of a convenient size that will easily fit in any cooler. The ice pack is refreezable making the ice pack an economical pack to use over and over. The ice pack is made of a durable molded plastic with a non-toxic fill of ultra-cool liquid contents. I absolutely love the easy grab handle which is ergonomic and I love the amazing blue color. The ice pack quickly freezes and lasts all day making packing your lunch and enjoying it nice and cool! This ice pack also works wonderfully to keep drinks cool when meeting up with friends for a barbecue so NO more using ice and dealing with the water as it melts making a mess! This ice pack is of a flat size making it perfect to insert in any cooler even a soft-sided lunch bag. An added benefit to the ice pack is that it has a 5-year warranty. This ice pack is a staple in my house for packing my lunch and I plan on purchasing more for other family members and friends. This ice pack is so versatile and lightweight making it the perfect accessory for anything you want to keep cold all day.

Rated 5 out of 5 by from Great Ice Pack This ice pack is thin and innovative, fits great into any lunch box. It is also lightweight and is great for traveling. Keeps food cold and is an excellent ice pack. Would definitely recommend. Perfect for the kids lunches.

Rated 5 out of 5 by from Great size This ice pack is a wonderful size. It can fit in a lunch box or a much bigger cooler. Their water bottles hold temperature great and so does this little ice pack. This thing stays cold for hours, especially in a good cooler.

Rated 5 out of 5 by from best ice pack ever I love this i bought as a joke but now im so glad i did it is the best i froze it over night and it stayed cold for 6 hours so happy :)

Rated 5 out of 5 by from Works Great! I am very happy with my Hydro Flask Ice Pack. I have used it in my small cooler to keep things cold. I have also used it to put in my freezer bag when I go grocery shopping. I put it in between my frozen or cold grocery's and it does great helping keep them cold. I like the hardness of the ice pack. So much better then the gel pack ones.
Date published: 2019-09-29
Rated 5 out of 5 by from Fits perfect in the backpack cooler. This ice pack is very convenient as it fits perfectly in the bottom of my Hydro Flask backpack cooler. This allows me to have more room in the cooler instead of having a layer of uneven ice at the bottom. I also love that it’s reusable and a non-toxic fill.

Lunch tote states it will keep items cold for 4 hours. If this item is added, will the cold time be longer? If so, how much longer?
