  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 Love my HydroFlask I bought 2 Hydro Flask (20 and 40oz) during "cyber week" sale. I love them. Keep things hot or cold. I mainly use it for cold drinks. Very happy with my purchases :)

Rated 5 out of 5 by from An absolutely incredible product I am someone who drinks a LOT of water, especially since I don't drink soda or coffee. As much as I love my 64oz HydroFlask, I don't always end up drinking the entire amount when I'm out and about, and by the time I use my water bottle again, the water inside is not good. So I got a 40oz bottle so I can drink all or most of the water I fill it with, leaving room for possible refills. I got a custom bottle and it is PERFECT. I am so freaking happy with this water bottle that I could skip. It's a perfect size for mid size trips or if I am in a location where I can comfortably refill my water bottle regularly. Again I love my growler but sometimes it's too much and this water bottle is a great addition to my collection, as well as being a great size for when my other water bottle is too much. Never thought I'd have more than one water bottle but this was a fantastic decision and a fantastic product!

Rated 5 out of 5 by from Just Right! I had the 32 Oz and it was great but because Hydro Flasks keep water cold I drank more water and would run out. So I got a 40 Oz and it’s the perfect size!

Rated 5 out of 5 by from Love it I enjoy the fact that I could fill it with ice and water at night and still have ice cold water for the next day. My Hydro flask makes it super convenient and I love it!! ❤️

Rated 5 out of 5 by from Great bottle! I love my hydro flasks! My most recent purchase was the 40oz bottle. I love the colors and the extra space over the 32. My only complaint is the paint seems to stretch pretty easily

Rated 5 out of 5 by from Best Water Bottle Ever!! I own a few Hydroflasks now and they're the only water bottles I've found that can actually keep my drinks cold throughout the day - even the ice stays cold for hours! They have amazing colors and I've fully eliminated plastic bottles from my routine. I hope everyone has one in the future so we can cut back on our plastic waste!

Does the straw cap fit the 40oz bottle? Does the straw reach all the way to the bottom of the 40oz bottle, as it would function regularly in the 32oz bottle? Or is it too short? If so, are there longer straw attachments?
