With the Survivalist Go-Bags mod enabled you're able to construct backpacks and duffel bags at the Chemistry Station.
They come in several different colors and they include a few different accessories so you can look good wandering around the Commonwealth.
There are also a few carry weights to choose from with one at +75lbs and another at +150lbs. If you're into adding a bit of realism to the game, you'll probably want this mod.
