We all know we’re supposed to drink a suggested 8 glasses of water every day, but I know quite a few people who barely drink a single glass.

Keeping water around and readily available, instead of a diet soda or latté, has really helped me stay hydrated. A couple years ago I was buying flats of bottled water, but in my quest to live a more environmentally friendly life, I found a better alternative.

A reusable plastic Nalgene bottle, like my older model pictured here, are an easy way to get yourself to drink more water. They have a 32 ounce marker at the top, so to meet your quota, just fill it up once in the morning and again in the afternoon or evening.

If you’re concerned about the toxicity of plastic containers, or just want something more stylish, Sigg makes similar bottles that are cast in aluminum and have a ceramic coating on the inside. Their website has many different colors and styles available.
