does it keep you from getting air in your stomach

No air in stomach, because you suck up the water, no air. It is very good, they have excellent service too.

i have no idea - i've never had trouble with this unit (nor has my family), but frankly not with any other water bottle or hydration packs either.

No it doesn't. Just helps to keep skin moisturized. It's a good product to use to prevent them. I am 8 months now and my stomach is really huge, haven't got one yet and I butter myself up twice a day right out of the shower.

Yes, it does....at least for me. This create sweats longer I stay in it. I've been using it from last five years.

It works as far as breathing goes. You won't struggle for air, but it isn't made to work like a genuine respirator.

It's shaped. However, it gives with pressure, such as your face against your pillow. I sometimes sleep on my stomach and I haven't had a problem with mask.

Hi! I believe to help keep any and all air out. I use mine and I love it!!! I sleep like a baby in it!!!

Yes - it doesn't affect your ability to sleep on your side, but you probably couldn't sleep on your stomach.

Not at all. Keeps air dry and slightly warm. My bet is there's some other cause for the odor.

No your nose is open on the bottom. It covers the top of your nose and keeps the wind from hitting your nose directly.

for stomach you need to get one of the pillows with a hole in the center - so I would advise it for you - ;)

It's referring to the inhalation of germs/dust and other things you want to keep out, though it does restrict overall air intake a little bit, as breathing through a mask or thin cloth might.

No, it doesn't. There is weather-stripping that goes in between the two shields and if properly installed, you get no air. If you do get air, its unnoticeable.

Not really. Works to raise vehicle under load then you deflate back to 5-10#. Only works under load

It does prevent air bubbles...by the way, I have tried every sippy cup. This is the only one I recommend. Hands down the best !

It does! I am very insecure when it comes to being in the gym. When I put this on, it surely helps keeps the stomach in position. After my pregnancy I got a lot of excess skin and most of my workout is running the treadmill and doing T25 or Piyo. I only work out under an hour since I workout during my lunch hour. I did not notice any sweat going onto my shirt within that hour. This waist trimmer is definitely one of the best I have bought. It has a good grip around your stomach without loosening up or having to readjust. Hope my feedback is of help.

Yes. It raises your chin, and helps keep your airway open. It also is helpful on your side by making room for your mask. Not a total solution,but helpful

No, it truly has a vaccum port so that you can remove ALL the air. Deflate wouldnt be enough to really get all the air out.
