  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 Just right for day hikes I purchased the 15L because I don't want a pack that is too big and bulky. This one is just right for 3-4 people. A wine bottle will stand up in it and the side pocket is perfect for napkins. Straps are comfortable. Top pocket opening is a little small, but good for utensils.

Rated 5 out of 5 by from Best cooler! We have had our eye on this cooler for a year but finally decided to get it after COVID meant we would be doing more BYOB outings. The cooler is stylish, and keeps things cold all day. I wish there were interior pockets to put flat ice pack, but otherwise it’s great

Rated 5 out of 5 by from Covid Perfect! Just drove my daughter across country from New Hampshire to Idaho. We did not want to interact with many people, so we bought one backpack that we could access for lunches and snacks in the car and one tote for food for cooking breakfast and dinner. We brought along some reusable ice, but since we didn’t have a place to refreeze, we had to resort to regular ice. We were on the road for 5 days and brought all of our food in these coolers. The only thing we did was empty the melted ice and dump out the water and refill with new ice in zip lock bags. Both of these products were perfect and so easy to wipe out to clean and reorganize for the next meal. I sadly left both coolers with my daughter as I flew back. I will be buying another backpack cooler for myself because during Covid we get together with friends on top of mountains where it is breezy and then we pop a beer! The backpack will be perfect for this. It was also super hot on our trip and these performed well. DEFINITELY A FAN! Thank you! This is a photo of Antelope Island outside of Salt Lake City. Definitely a cool place to go, if you are road tripping and need to stretch your legs!

Rated 5 out of 5 by from Excellent backpack cooler I bought this a few weeks ago to use on a week long beach trip. Very well built and easy to carry. The straps were comfortable and the fabric hook on the back made it easy to lug out to be beach and back every day. Kept the beverages very cold the entire day in 85-90 degree heat. Able to fit 15-18 12 oz cans in the 15 L depending on the amount of ice used. I would absolutely buy this again, well worth the money.

Rated 5 out of 5 by from I love my cooler I absolutely love it! I bought this over the Igloo backpack and I’m so glad I did. I’m 5’5” and 115lb is carrying a hard cooler with one arm while full is impossible! I can carry the backpack full with no problems, and I still have my hands free for other things. Quality material, quality zippers, and perfect side/top compartments for keys/card/phone/small snacks. 10/10 would recommend!!

Rated 5 out of 5 by from "Skeptical" to buy it and try it! My wife could not believe I bought another cooler. This is the first backpack cooler and I strapped it on my back for the first time Memorial Day weekend. I'm very impressed with the performance, ease of use and how practical it is to have a spare hand for chairs, umbrella, etc.

Rated 5 out of 5 by from Excellent! We are so happy we FINALLY bought this. We have been eyeing it for some time and finally pulled the trigger. We take it down to the beach, picnics, we can carry the perfect amount. I prefer this size over the larger version, because you can't pack TOO much and make it too heavy for yourself, so it fits exactly what we need in it.

Rated 5 out of 5 by from Obsessed I have used this cooler nearly every day for the past month. I was looking for a drink/day cooler that's easy to take in the car, on a bike, rafting, etc. and this totally fit the bill. Love the 15L size, easy to carry as a pack. I've already convinced multiple friends to get one!

Rated 5 out of 5 by from Great Build Quality--Perfect for Day Trips I purchased the 15L Cooler Pack in black about a month ago. I purchased the bag as an easier way to lug water, drinks and snacks to all day sporting events for the kids. I wasn't expecting the bag to be as comfortable to carry as it was. The straps are lightweight, yet are very supportive. The bag itself kept the drinks and food cool all day although it is winter and I haven't had the opportunity to put it to the test in the heat of summer. I found the material of the bag and the construction of the bag to be excellent. In the month or so I've used the bag, it still looks new. My only gripe with the bag is the side bottle pocket feels thin and I'm not sure how it'll wear over time. Other than that, for my needs as a day pack, the bag works great.

Rated 5 out of 5 by from Love the Pockets and how lightweight it is! I am really excited about the various pockets on this back pack. I also really appreciate how sturdy and supportive the straps are. I am excited to use this hiking and by the river in the hot oregon summer! I did a trial run with ice packs and some drinks, and I thought it did great for how lightweight it is.

Rated 5 out of 5 by from Amazing I can't say enough about this cooler. Hands down the best I've ever had. It's so lightweight that it's hard to believe how good it works. A couple ice packs and your pre chilled items will stay cold, not cool, cold, for over 24 hours. The pockets make it easy to access your choice of items and the top zipper allows super easy access. We take it everywhere!!

Rated 5 out of 5 by from Well made cooler! I got the Hydro Flask 15 L soft cooler a few weeks ago. It is a soft canvas cooler with plastic inside designed for keeping your stuff cold longer. I like that it is lightweight by itself. I love that it’s designed like a backpack, convenient if you need to free up your hands. It is comfortable to wear on your back, there is extra padding so that you do not have anything hard poking your back. There are a couple small places on it to store stuff that you want to keep dry. To open and close there is a zipper. It is an aqua seal zipper to keep from leaking.

Rated 5 out of 5 by from Good looking and convenient I really like this cooler pack because personally I love backpacks and being hands free and this accomplishes just that and it looks fresh! The design is what makes it the most appealing in my opinion - I got the mist grey and its very modern minimalist looking, which I love. It holds a lot and the straps hold up really strong. The side pockets are really convenient too to store the little things like your wallet, keys, etc. without getting them cold or wet. The one thing to keep in mind is the size - while it's great to hold a large capacity of food/drinks, if you're a smaller person it can be a little overwhelming. I am 5' 2' 120lbs and when full the bag is very big on my body, but that is the case with any backpack or large cooler so its not a bad thing, just something to be aware of. I highly recommend!

Rated 5 out of 5 by from Love everything about it! I love my Hydro Flask 15 L Soft Cooler Pack - Black. It's a really nice size, nice color, nice texture, nice size straps in the back of it to carry it on my shoulders so I don't have to worry about carrying it with my hands, nice size wide mouth on the top of it so that many items can go inside of it to keep them cold. When I put some ice inside of it, the ice stays inside of it for almost the whole day keeping my drinks and food I had in there really cold and the ice doesn't melt if at all. The blue insulation inside is made of really nice thick material and the black material on the outside of the coolor back is made of really nice thick material as well. I accidentally dropped it on the floor a couple of times and no ice or liquid came out or leaked outside of it. The zippers are really thick as well and prevent any liquid from leaking from it. Without anything inside of the coolor pack, it's really light and easy to carry. With ice and drinks and food inside of it, it's still light and easy to carry. There are several pockets on the outside of it that allow me to put my phone and my car keys inside of them. I have gotten many compliments on the coolor pack that it's a nice size and shape and many drinks and food fit inside of it and keep cool. I have taken my cooler pack to almost every event I have had that's outside so I can keep my food and drinks cool in this hot weather. When emptying the coolor pack of anything that's inside of it, it's really easy to empty it out and clean.

Hydro flask is continually creating the best products for keeping items cool (for this Texan) or hot! Seriously, the quality is unparalleled and the colors are fun! Highly recommend.

Rated 5 out of 5 by from Great Backpack cooler I bought this a month ago and took it to the beach. Kept beverages cold with a small amount of ice. Easy to carry on back while riding a bicycle. The hands free is priceless! Another great feature is the dry pocket on the lid and the fact that the cooler stands up without falling over. Go on and get this, you won’t regret it.

Rated 5 out of 5 by from I love this cooler!! This cooler is amazing!!! The backpack design of it (with front chest snaps) is so comfortable and easy to carry. I packed a lunch to take camping with 3 ice packs, 2 cans of soda, 4 bottles of water, 4 sandwiches, container of tomatoes, cucumbers, salad dressing, and snacks in pockets. It was easy to carry the food, and the next day....well after 24 hours, drinks were stilled chilled. It is very easy to clean out too. Just wipe it down leave it to dry.

Do any coolers in your Unbound series float if accidentally dropped in water? I'm sure these weren't built to constantly be submerged, but am wondering if this would instantly sink if it went overboard while paddle boarding. Thanks!
