As consumer magazines go, Which? is probably the best known and without a doubt the most difficult to get a great review in - why ?... because they are industry agnostic and have an internal policy of complete neutrality which ensures their readers get the absolute lows and highs of any product they review. Brave then of Montane to send the Atomic Jacket in for test ?... no, not really, with quality as high as Montane's there's little to fear of an independant review, but what a review it turned out to be.

Atomic DT Jacket - Best Buy - Which Magazine - October 2009
 
The lightest jacket on test at 312gms for a Large.  A good jacket for all but the coldest days.  Comes with it's own stuff sac.  Drop tail, long arms and finishing at the waist.  Reflective strips aid visibility - something our tester thought to be a good feature when caught in fog on Mount Brandon on our Irish Three Peaks Challenge.
