Packing light for a short trip is a skill that has less to do with specialized travel gear and more to do with being realistic about what actually gets used over a couple of days away from home.
Plan around outfits, not items
It's easy to pack item by item — one more shirt, one more pair of shoes — without stepping back to see the full picture. Planning around a small number of complete outfits, and choosing pieces that can be mixed and reused, tends to result in a noticeably smaller bag than packing piece by piece.
Assume you can buy anything you forget
Most weekend destinations have stores. Packing as though any forgotten item is unrecoverable leads to over-packing 'just in case.' For most short trips, it's reasonable to assume that anything genuinely essential and forgotten can be bought once you arrive, which removes a lot of the anxiety that drives overpacking.
Repack the same way each time
Packing the same way for every trip — the same order, the same general list — reduces the mental effort involved and tends to result in a lighter bag over time, simply because it removes the guesswork that leads to over-preparing. A short, reusable packing list, even a rough one, tends to be more effective than starting from scratch each time.
