I've had a Vulcan for over 10 years now, and have taken it all over the place, usually by train.
I like the fact it has a handle on both sides. The rear facing zip on the top pocket is lovely as it means you can get a travelling companion to put things in the pocket without having to remove the very very heavy backpack.
You can wear it over the top of a set of PLCE webbing without much issue.
And of course it's bomb proof. I got mine second hand, previous owner was the Dutch Para's...
Only 2 downsides I have found
- If you put PLCE side pockets on it, it doesn't fit through the X ray scanners for the eurostar, meaning you have to take them off to get it through
- Being so big, you can easily and quickly over fill it. Just because it allows you to carry the best part of 100lb, doesn't mean to say it's a good idea to do so.
I do love my Vulcan, and I do use it for trips where I need that volume/weight.
Thanks
