No affiliation with Lululemon, but I recently got this belt bag for travel and running errands around town, and love it. I am not a frequent poster, but I read here often enough to know this crowd shares my love for all things travel bags:
This is not large enough to replace a purse, and not small enough to replace a hidden belt, as many people here like. But for times when you want to be hands free and carry a few cards/ID and a phone, it's perfect. For day to day I find I like it best for the farmer's market, so I can save my hands and shoulders for my food haul.
It's a little on the pricey side, so if you need to give someone a gift idea for you, this could be a good one.
