This is a decent enough tripod bag. It fits my TR343L with BH50 well. The carry strap is nice and the bag appears to be pretty well-made thus far. However, the interior Velcro straps are more of an annoyance than useful. I cut them off, as I prefer to just throw my tripod in the bag and go. The exterior pocket is useful. I store tripod-related tools there.
My biggest disappointment and I hope that PMG reads and acts on this: This bag is made in China. There are many great manufacturers in the US that produce superior products competitively. I can steer you toward several that would make better bags that fit well with your "built in USA. Just let me know if you're interest.
I bought a TR344L (which is a awesome tripod although I have not yet taken it on the road) and I also own a RRS BH-55 Ball head. Needed a bag to carry them both, I bought the 28 inches VSBAG and I was able to fit the tripod and the ball head in the bag - I'm Satisfied customer!!
