Packstack

Packstack turns a general gear closet into trip-specific packs. Items can be organized by category, reused across lists and marked as base weight, worn or consumable, producing a clearer picture than one undifferentiated total. Checklist mode helps with the physical packing step, and the paid tier can handle multiple people or loadouts. A LighterPack CSV importer lowers the cost of moving an existing inventory. Calorie planning combines trip and body inputs for an initial food estimate.

A low base-weight number is not proof of a safe kit. Entered weights may be manufacturer claims rather than measured values, and a calorie or water estimate cannot model individual physiology, heat, altitude or an unreliable source. The free tier also limits the number of lists, while advanced planning is paid. Weigh critical items, test the complete load on a shakedown hike, and use the checklist to notice missing safety systems rather than to chase a cosmetic target. Group equipment must be assigned explicitly so that shared assumptions do not become omissions.
