In reply to ianuk:
Columbia don't seem to have caught the imagination anywhere near as much in the UK in comparison to TNF, Patagonia etc and consequently their brand awareness and market penetration is on the low side. I'm not surprised you haven't heard of them. They are a long established US brand and are literally huge in the States. I have several items of Columbia clothing - trousers, fleece and soft shell. All are very well designed and made so if you really like the Jet Stratus jacket, I'd get it.
Hope this helps.
