Just bought a Karrimor Phantom Jacket II & a pair of Craghoppers Pakka Lite overtrousers (ladies size 12!!) Both have their own stuff sack and fit in my bumbag along with hat & gloves which is 9"x7.5". I only wanted the trousers but decided to upgrade by old Karimor packlite jacket which is OK but does not squash into a bumbag very well at all. I was surprised by Winfields which is where I got them - they have loads of camping/outdoor stuff in stock - a lot of cheap end Regatta and the like but other high end stuff as well at Internet sort of prices.
