In reply to katiep:
I have a 'medium' and am 6'0 & 70 kg, so I think he'd be wanting a large. I definitely couldn't get a fleece under mine, (well, not a chunky one) never mind two of them. It's pretty warm though and not sure you'd really need anything other than a decent thermal or ultra-light fleece, unless you're doing some long-term hanging about in very chilly conditions.
If I were in the market again, I'd probably get a Mountain Equipment Lightline which doesn't cost that much more but felt like it had slightly better design features. These are just small things, but definitely noticeable.

If bang for the buck is what you're after though, the Filo is probably your best buy, unless you can find a Lightline at a knock-down price.
Edit: just checked the Lightline price and it's now more than I'd seen last year...by quite a bit! (I'd tried one on sale at £149) It's not a direct / fair comparison then, so you can ignore my earlier comment above.
