Extremely strong glass. Very thick. I would think if you left room for some expansion of frozen liquid, they should be fine. I have not tried freezing anything in them. This is only my opinion based on how sturdy they are.

I would not freeze milk in these. You can freeze your milk in storage bags and thaw them to put into the bottles.

I've never tried to freeze them, but they are dishwasher safe so I would assume that means they are able to be frozen. They don't expand like a throw away bottle would so you would just have to be careful to leave room for the liquid to expand.

Yes, i always had problems with bottles breaking from multiple freezings. This one holds up great! I fill it 3/4 full and leave the lid off every night and it's ready to go the next day. I just ordered five more of these specifically for this reason

I left them frozen. however, it truly depend what you are trying to keep cold and where you are. I kept the packs frozen because I was traveling through AZ and CA in the summertime. We are supposed to keep the insulin cold, but not frozen. Maybe you can keep the bottles or pens near the area but not touching?

What do you mean? You just fill them up, put the cap on tightly, and lay them down in the freezer. No spilling. No leaking. Awesome!

For long lasting ice, save your 16oz water bottles. Fill them almost full with water and leave the cap just a little loose and put them in the freezer. When frozen securely tighten caps. Use the frozen bottles in place of ice cubes to keep an ice chest cool and they will last DAYS, and you can finish them off as ice water. I've done this for years and it' amazing how long they remain frozen.

They are not air tight - liquids seep out if you turn them on the side. I use them in the frig and for pantry storage but have never used them in the freezer.

I've never tried freezing but really like them for my daughter. They're safe and a great size and I feel that I'm not microwaving chemicals. I am sure if you google the mfr instructions it will specify. I bought 4 and am glad I did!

Yes, these work great for freezer storage. I have froze breast milk and homemade baby food for 3 of my children in these, and have never had problems. They go directly from freezer, to bottle warmer to dishwasher with out any difficulty.

Looking at the date of your question you may not need this answer any more but I was curious about freezing in the Medela bottles, too. I looked on the Medela website and they have the following posted "Flexible: Ideal for expressing, storing, freezing and feeding breastmilk".

Have not attempted this, but I feel confident that they would hold up for a single use if they went immediately into the freezer. I am equally confident that they would NOT hold up for more than a single use and/or if the water were significantly hot when put into the container. Hope that helps.

I attach these to my outside faucets to somewhat purify my dogs water. In the winter, I completely take them off and wrap my hydrants. Sorry that I could be more help. I would figure they would freeze though unless you alowed a large amount of water to flow through them.

I have not used for freezing food but think they would work well. They are a heavier plastic than some and quite airtight. 2oz is still quite small.

Accidentally answered yes to this. I have never tried freezing with these. Not why I bought them. Sounds a little scary. Would think the glass would easily break.

YES! We love these sport bottles. They keep the liquid cold, if you put in enough ice, in a hot car for hours! My whole family uses these bottles :) I just called to get some replacement parts because my one child likes to take them apart and lost some of his the stoppers. He also broke the spout off and they replaced the broken and missing pieces at no cost and no questions asked! Lifetime warranty.
