The present perfect connects an earlier action directly to the current conversation. When you say that someone has packed the rain gear, the packing occurred in the past, but your focus is on the fact that the bag is ready now. You also use this structure to discuss lifetime experiences up to this moment and ongoing states that started in the past.
We have packed the tent, so we can load the car now.
