Fits conveniently in the FlipBelt and is relatively secure. With the bottle completely full it moves up and down a little bit while running but becomes pretty secure after you take one or two drinks.

I love their recipes. They are easy to make and use many of the ingredients that I already use in my cooking. If you are using something that's fattening they just replace it with something less fattening. I have made many recipes from their magazine and I just love it.

I keep one at work, one at home, and I travel with one.. oh and one in my "walk of shame" bag (that bag stays in the trunk and has all my essentials for a spontaneous moment). ;-). If you are considering buying this product, my purchase history should tell you something. :-) I really do love this stuff. You don't have to be ashamed to go when you are out and about or spending the night away from home. I think every one should carry one, especially if you don't know when the feeling will hit you. I especially think ladies should use them if they have to go while at work. I can't STAND going into the ladies room and that smell hits you at the door. it just makes me gag and I feel contaminated... like the smell is all over me.
