  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 Hydro flask I received this product in exchange for my honest review. First off the color of this bottle is beautiful. Second, whatever you put in it stays cold all day long along with the ice. Great for long trips for hiking

Rated 5 out of 5 by from Keeps it cool This hydro flask is perfect for both cold or hot drinks. I use it mostly for keeping my water ice cold but I have also used it for coffee in the past. The color really makes it unique. All of their products are good quality.

Rated 5 out of 5 by from The best waterbottle I love my hydro flask. The color is cute, the size is perfect (not too bulky or small), and most importantly, it keeps things cold. I’ve tried a lot of other brands and nothings keeps my water iced longer than a hydro flask. And they’re super durable and last for ages. Highly recommend

Rated 5 out of 5 by from Great water bottle! There are so many things to love about this water bottle. It has such a minimalistic and sleek design, and the color is very bright. It's the perfect size for urban day to day use. Its tall and skinny design makes it easy to carry around, and it fits in my car's cup holder. I like that it has a carry strap so I can grab it or even use the carabiner to attach it to my bag or bicycle. The coat is grippy in texture so it is very easy for me to hold onto a bottle, but still slippery enough to slide into any pocket or corner of a bag. The lid is easy to open and close with sweaty hands and it's completely watertight. It really keeps your drinks cold/hot for said amount of time and the mouth is wide enough that I can put ice in the bottle as well as get a brush in there to clean it. Unlike some other bottles, It is comfortable to drink directly from because the threads are on the inside of the mouth spout so lips cannot touch screw threads. I definitely recommend this water bottle!

Rated 5 out of 5 by from Perfect size for an afternoon walk I have different a collection of drink containers and this 21 oz standard mouth bottle is one of my favorites. I have one for different occasions and use - bigger bottles for longer trips or carry more volume, smaller bottles for a short walk or trip, gardening etc. It's harder to drink from larger bottles, especially if riding a bicycle or driving a vehicle or doing some activity - the 20-24oz size bottles are perfect. This came with a shoulder bag/strap which makes carrying the bottle much more easier/comfortable. The keeps cold and hot drinks - great for a cold water/lemonade or power drinks, or for coffee/tea. Good simple design - nice teal color on the bottle.

Rated 5 out of 5 by from Holds ice very well This keeps my drinks super cold. My husband's ice in his bottle melted hours before mine did! I love being able to have a cold drink all day. My only downside is that the lid can be a little hard to open sometimes.

Rated 5 out of 5 by from Love it The Hydro Flask in laguna blue is so nice. Love the make? Versatility and ease use of product. Cleaning is easy plus got the sling to go with it. You can’t go wrong with the set. The sling also has clips and a pocket. Overall I love my hydroFlask products and recommend highly!!

Rated 5 out of 5 by from Worked great! The Hydroflask 21 oz standard mouth bottle keeps my drinks nice and cold for hours. With the temperatures outside rising,it is really nice to have a bottle that actually keeps my drinks cold for long periods of time. Easy to fill and clean with a standard bottle brush, this is my favorite way to carry beverages on my adventures.

Rated 5 out of 5 by from Always a Winner! This brand of water bottles has never disappointed. Keeps my water cold all day. And if I use ice, sometimes I have ice in it the next day. Only great things to say about it. This size is a perfect size to pop in my bag and go. Haven’t tried it for hot drinks but I’m sure it would work just as well.
