A staple for hiking

These are a little bit harder to drink out of than a hard-sided bottle, but the fact that they are super light weight and take up no room when empty makes it worth the trade-off. And, I have found that they work great to keep wine fresh. Just pour it in and squeeze the air out. Platypus makes a version of this bottle that is labeled for wine preservation, but the only difference I can see is that the wine version is a darker color and more expensive. If you are keeping it in the refrigerator, then it doesn't matter.
