If you can't stand getting a swig of warm water on a sweaty hike, you'd be wise to invest in an insulated bottle like this one. While an insulated metal bottle will typically be a bit heavier than a plastic bottle or an uninsulated metal one, this model is still relatively lightweight, and worth it for the ability to keep your water ice cold for over a day.

If you're going to be hiking somewhere that has some sketchy water sources, you will definitely want to bring a Lifestraw.

The filter removes microplastics, chlorine, and organic chemical matter, as well as sand, dirt, cloudiness, and up to 99.9 percent of waterborne bacteria. It can also filter up to 1,000 liters of water before needing a replacement.
