The Maxpedition Fatty EDC works great for traveling with a few pipes, if you want to fit more get the " Beefy EDC " that one can hold more.
I also have the Maxpedition Water Bottle Holder that is a nice size ( 10"x4", holder fits a 32oz/1L Bottle ), so lots of room for pipes and tobacco. It also has an exterior pouch that is a good size.
I have the Camera Lowpro Carry Bag for traveling with more pipes etc.
The Shaving Cases work well also for transporting pipes etc.
I also have an Aluminum Cigar Tube/Travel Humidor with a built-in humidifier and hygrometer.
It can hold up to 1.5oz's of Tobacco easily and will fit into the Water Bottle Holder and the larger Camera Bags.
This is actually for cigars, but I use it for trips out of town lasting a couple days or more.
The Maxpedition Medium Jumbo E.D.C. S-Type Versipack will accommodate the other bags of the same brand with the 3" Tac Ties. Many Maxpeditions are attachable to each other by using this system.
Amazon does have other bags like the Maxpedition that are not as pricey, but I think the quality of the Max is better.
You don't have to buy pricy items or items that are called "Pipe Bags ", just use your imagination.
As long as the pipes will be protected which I think is the main concern, there are lots of options.
