Your hiking lunch needs a hard-sided box

A hard-sided lunch box is the single best fix for the trail-squished sandwich problem.

Crushing is easy to solve: keep soft stuff in a rigid container, not a soft-sided bag. If you’re already using a soft lunch bag, put a hard plastic box inside it. Sandwiches go in a Tupperware, fruit in a small container, chips in a sturdier tube or packed upright. The real trick is filling the empty space so nothing moves. Use a cloth napkin or a bag of nuts to wedge things still.

For freshness, skip the ice pack. Freeze a water bottle and rest it on top of the food. It keeps everything cold, thaws slowly, and gives you drinking water by mid-day. Put the lunchbox in the center of your pack, away from your back (body heat) and away from the top (squished by your rain jacket). And don’t bring anything with mayonnaise. Heat and hours will do it no favors. Hard cheese, nut butter, cured meat, dried fruit, or a heavy wrap all hold up fine.

Future sandwiches deserve a fighting chance.
