NO. Placing a SIGG bottle in the freezer with liquid in it will cause the liquid to expand, causing extreme pressure on the inside of the bottle which may crack or split the aluminum.

Well, that advice is good if the bottle is over-filled.

My solution (and I have done this with 2-liter bottles) is to fill about 2/3 full and place in the freezer with the lid off. After the ice expands, it should come close to the top. Then, you can add a little more and let that freeze. Finally, after everything is frozen, you can add the lid. Then, you should be able to do whatever you want to with the bottle.

But... if you cap a frozen bottle and let it thaw, there will be a slight vacuum on the bottle. The lid might be difficult to get off. And, if you open the bottle be sure to freeze it again before re-capping.
