In reply to David Staples:
As Andy said they are standard issue in our MRTs which was due in the case of my team to an un-refusable offer from Keela.
I personally don't like the Munro, I find it heavy (they don't quote a weight on their website), bulky and I've had issues from new (read, fresh out the packaging) with the waterproofing.
Would recommend shopping around and finding a decent gore tex jacket for around the same price
