I use the LUNCH BAG LARGE daily for work and it easily holds breakfast, lunch, snacks and a water bottle. The insulated three-layer build keeps things cooler for longer, and the roll-top closure with welded lining has not leaked when I store it upright. The inner surface wipes clean fast, which matters after a messy salad. The removable, adjustable shoulder strap is handy when my hands are full. It is made from recycled PET, a nice bonus. Only note: roll it properly or it may not seal as well.
