I just wanted to post a tip for Protein shakes and other portable beverages. The tupperware tumblers with flat lids (not sippy lids or sports lids or ones with straws) are absolutely great. You can put your Protein powder in and throw it in your bag. When you want to make up your shake, fill it 2/3 with Water and shake the hell out of it. It won't leak. Then after you drink it (out of the tumbler itself), put the lid back on and toss in your bag. Again, won't leak. I have found these to be great. I get the 11 ounce ones. I have four so one or two are always clean and dry and ready to go. You can get them cheap on eBay but I just got the "rainbow" set. It was $27 for the set of 4. My shake is only 8 ounces made up so these are plenty big, though you can get 16 ounces too.

The normal protein shakers are ok but they are big and in my opinion not very portable. I also find that they can leak from the pour spout and the ones where the lid just snaps on can make a mess if you snap it off wrong and fling your shake everywhere.

If your protein doesn't mix easily you could get one of those whisk balls and throw it in with your dry powder. I don't have this problem. I also use one to mix a medicine I have to take with juice.

Thanks for the tip - I will look these up

I am always on the lookout for a better transport method. I don't leave home without a dry mix of Protein shake in a tumbler of some kind. This is great. Thanks so much!

I use these too, I have a 11oz fruit set and two seasonal 16oz. I do preamble shakes but always have this filled with water for me to drink! You are right tho no leaks and the "spout" type thing you drink from is small, I hate big openings like Nalgene bottle, I dribble lolol!

Mine doesn't have an opening in the lid. It's just flat and you take off the lid and you have a plain cup. But the lid seals very well and doesn't leak which to me is the best part.

These are the ones I have not sure if it will post the pic

I have had good luck with no leaks with these.

I have a couple of the blender bottles as well. I like them as I seem to want to shake my drink again after a few minutes of it sitting on the desk while sipping away at it! The blender ball really helps with mixing up the Protein powder very well!

Thanks for the info I'm off to eBay

Me too! I carry a tall and a short one (pre-filled with powder) on every flight. On the road I use the short one for my pre-workout Breakfast and the tall for my lunch or afternoon snack (depending on what my work day/customer interaction is like).
