I love the RAB Bergen. It's light, works well and fits fine for the price I paid (£99).
Just a couple of gripes.
I wish the hood would either roll away in a collar or detach completely. I find most jacket hoods a waste of time and never use them. The problem is that the hood just hangs from its Velcro strap (no matter how tight you try to roll it up) pulling your collar down and exposing your neck to a nasty draught.
Also, a pair of hand-warmer pockets around hip height would be nice. Whilst the pockets the Bergen has a convenient for stowage and neatly avoid any rucksack straps, they're a bit high for general use.
Also, be aware of sizing. I'm 6'1" with a 40" chest and the small fits me fine. A medium would be far too big on me.
