S'well insulated water bottle Any sustainable girl worth her Himalayan salt has a good water bottle. Maybe three. (I have one for my purse, one for my workout bag, and a backup in the pantry.)

And because this item is such an essential part of our lives, it's important to get one you really enjoy, that is practical and beautiful.

S'well is this water bottle. I got one to try out from ABC Home*, and it has become a fast favorite. First, it has a slim, attractive line that feels good in the hand. It keeps drinks hot for up to 12 hours, and cold for up to 24 hours, without any condensation on the outside – ever. I can attest to this, having walked 25 minutes through 10-degree temperatures to the gym. When I uncapped the water bottle, the water inside was still at a comfortable room temperature, which was so nice. I've just been using it for water, but it would make an excellent tea or coffee container, too. #multitasking

For every bottle from the Wood Collection that is sold, S'well plants a tree through their partnership with American Forests. They donated $100,000 to the U.S. Fund for UNICEF’s campaign to help provide access to clean, safe water to the world’s most vulnerable children. And it's pretty cool that it's 100% owned by a female entrepreneur.

I mean, perhaps I'm biased. After all, it does come in the EcoCult colors, electric pink and grey, as well as alligator and his and hers.

I totally recommend it as your water bottle of choice.
