Knowing how to pack a tote bag for travel is key to maximizing its convenience. Use the bag’s exterior pockets for often-used items like cellphones, keys, water bottles, or an umbrella. Store warm or cold food in the insulated compartments, which are designed to keep things the right temperature and wipe clean in case of spills. Chips, cookies, and other snacks tuck easily into the non-insulated compartments, and some totes even include padded sleeves that protect electronics like laptops and tablets.Related:  How to stay organized for any trip.
