Conventions, conferences, private events - to say I travel with my Vive a lot is an understatement. Here is my list of traveling cases that are cost effective to something more sturdy that I wouldn't mind taking on a plane. If you have any alternatives you'd like to share, I want to hear about them email@example.com.
The most cost effective for someone who is on the go. All of the Vive accessories will fit in this backpack. You can customize the velcro inserts to try to keep things from shifting around. The bag isn't padded much, and because of this, I wouldn’t suggest flying with your equipment in this bag.
The Pelican 1504 delivers a robust traveling case for the Vive. This ATA approved case is perfect for traveling with on a plane.
This case works great with the Pelican 1550 Lid Organizer (pictured above). Pluck the foam to craft a secure carrying case for your equipment. Design exactly what you need; Got 3 controllers and 3 basestations? Not a problem for this case.
BaseReality made this case specifically for traveling with the HTC Vive. While it is durable and secure just like the Pelican cases above, the custom foam also means it is slightly more expensive. The case comes with a dual-layer design that allows you to store all of your accessories, headphones, and much more. The red inserts make it easier to see where everything belongs and help you identify what is missing when you are packing up.
