Ditch the hard lunch box. Take a soft cooler (or none at all).

For a long hiking trip, skip the rigid lunch box and use a soft cooler or a dry bag—it’s lighter, weighs nothing when empty, and stashes flat in your pack.

Hard lunch boxes are heavy, bulky, and they don’t compress. Every gram counts when you’re carrying it for hours, and a hard plastic box is dead weight from the moment you leave the car. A soft cooler or insulated dry bag gives you the same cold-keeping power for a fraction of the weight, and you can shove it in a corner when it’s empty.

What you actually want to bring isn’t a “lunch” anyway—it’s a bunch of snacks you eat over the day. Calorie-dense stuff that survives the trail: tortillas instead of bread (they don’t squish), peanut butter, hard cheese, salami, nuts, dried fruit, dark chocolate. Skip anything that melts or needs a fork. Use a honey packet instead of jam—it won’t soak through the tortilla.

Freeze a small water bottle the night before and throw it in as an ice pack. It keeps things cold for hours, and when it melts you have drinking water. Eat the heaviest foods first, and you’ll lighten your pack as you go.

This is not the place to be precious about your sandwich. Go soft, go snacky, and your back will thank you.
