2Pcs Lunch Tote Shoulder Bag, 15.6"

It slides right under a plane seat and still has room for my 15-inch laptop, which was the main reason I bought it. The two separate pockets keep my lunch container and office stuff from banging into each other.

The insulated lining actually kept my lunch cold for a good four hours, and the 15.6" size fits my laptop perfectly for work. I was worried the handles would dig into my shoulder, but the strap is pleasantly padded. For the price, you're getting two solid, versatile bags.
