  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 Perfect lid never spills Perfect replacement, love the handle. I tragically lost the inner silicone piece and never thought I'd be able to use my Hydroflask again until I started my search online for replacement lids. Hilariously this was the last place I looked. I'm so happy. It's a 3-piece lid so difficult to clean, but that's what makes it so good. It never spills. The top half spins to open and close and it feels pretty secure. Fits great on my coffee Hydro Flask as well. I swear I let it roll around in my laptop bag with no fear.

Rated 5 out of 5 by from Your customer service is amazing I ordered this lid and it leaked between the top and bottom where it twists. I sent a note to customer service online and the next day a new one was on the way, no questions asked. I love this lid because the strap makes it easier to carry and it comes apart for easy cleaning and it is easy to open and close with just a twist.

Rated 5 out of 5 by from Gets the water in my mouth. I can drink my water without my dumping it all out the side of the wide mouth opening. Thanks. Nice.

Can I use this cap to serve drinks as well? Like filling a cup?. Or does there have to be a sucking motion?

Asked by: The A
Yes, it will not pour out extremely fast, but it will work.

I took the lid apart to clean it, then screwed the top two pieces together first. Now I can't get the third piece back on and I can't unscrew the top two pieces. Is there a trick to this?

Where can I find the sku# for this lid? I am trying to do a warranty claim but I cannot find the sku#. I've bought 3 coffee Wide Mouth Flex Sip and they all started leaking.

I am missing just a part of the wide mouth flex sip lid. I have the bottom piece and middle piece, but my purchase exluded the rubber part and the top part that is used to open and close sipping part of lid. I'd like to replace just the missing items

Is it easy to open this lid with just one hand? Looking for a water bottle that I can use while sailing that doesn't have a cap/lid that separates from the bottle and can be opened with one hand! Thanks!
