In reply to Bash:
I have a Borealis and VR Summit in the same size (medium), they both fit exactly the same on me. I'm a 6'2" 30" beanpole. I would love it if they were both a bit longer in the torso, but they're still OK.
For what it's worth, as much as I like Rab gear, I find Mountain Equipment is just a bit longer in the torso and arms, and so tend to buy their stuff now. I'd have gone with the ME Kinesis over the VR summit, just a slightly better fit, and stuffs in it's own pocket, which the VR doesn't.
