PackRat helps outdoor travelers plan trips and build better packing lists. Search a large catalog of outdoor gear by keyword or natural language, compare products on weight and price, and assemble packing lists that are analyzed for total weight with a base, worn, and consumable breakdown. Ask for lighter alternatives to the heaviest items, find gaps for a specific trip, check the near-term weather forecast for a destination, browse outdoor guides, and save trips and packs to a PackRat account that syncs with the mobile app.
