I like my lunch bags like I like my men: With a built in insulated lining. That doesn't really work, but it's the best we could come up with as a group that was suitable for the website. The good news is that this cute bag has an even cuter design, and an even cuter purpose: Keep themes lunches cold! With an insulated design, and enough room in there to store a delicious lunch (and then some!), this bag really hits the spot... same way a good man does.
