Kate, Your talk of a water bottle made me think about one that my friend Jenna won't stop talking about. She was like a walking advertisement about it. First she texted me about it with pics and then when I saw her she showed me it and told me about why it's the best. It's called s'well and I've meant to mention it for the past few weeks because if there's one thing we all need in the summer it's a good water bottle. This one is stylish as well. I especially love the one below from the textiles collection. Jenna had a mint green/aqua looking one which made me want to drink from it because it looked so refreshing. You can read all about why it's the best water bottle here.
ps. It's also charitable so get on it!
