24 oz. Hydroflask

The 24 oz. hydroflask is a must for any aspiring coffee shop "it-girl". Not too big to be gluttonous or unwieldy, not too small to be unhelpful. Pick a color that says, "I had go into three different REIs to find this one". Keep it nearby at the cafe or the park to help stretch out an afternoon of squinting at Joan Didion and journaling about the complexity of your TJ's run.
