I obtained my Rab Vapour Rise equipment ([jacket and pants] before it was announced that Rab would be entering the US market) December 2005/January 2006 directly from Rab on a Professional Courtesy basis because I am a Professional Nature, Landscape, and Wildlife Photographer here in the US. Unfortunately, right now I have to lose some weight to fit back into the pants.
I had decided to get this equipment having previously received and liked the older Vapour Rise Top from Prolite Gear in Bozeman, MT. I like this gear very much but haven't used it enough to do any kind of review. Mark Verber uses the Vapour Rise Jacket fairly extensively.
But, right now, Jackson Sports in the UK is a good source for getting the Rab Equipment and having it shipped to you here in the US. At this point, very little Rab equipment is brought into the US until Rab gets its distribution set up here.
Here is a link for the Rab Vapour Rise Jacket from Jackson Sports:
Hope this is some assistance.
