The short answer is: sealed compactly. Here’s what it means in practice:Use Lightweight Options Whenever PossibleNot every food can be replaced with a lighter version, but there are definitely some that can.For example, opt for energy bars or gels instead of a heavy bag of trail food. You can also ditch canned food for food in compressible packets and sachets. Dried food can replace fresh fruits. These small changes will make a big difference in your backpack’s weight. Remove Excess PackagingMarketing makes food manufacturers use packaging that isn’t always conducive for a light backpack. Once you’ve prepared the food you want to take with you, transfer it to a more compact container, or remove any of the unnecessary packaging.For example, just pack the muesli bars singularly, not the entire box. Divvy out portions of what you’ll need from larger containers, like powdered milk and nuts rather than taking the entire bag.
