Arc’teryx Squamish Kept Name & Acclaim but Tests Not the Same
Like the 2013-2014 Patagonia Houdini, the 2014 Arc’teryx Squamish windshirt kept the same name and its acclaim but, the test results aren’t the same.
For 2007 – 2008 the Arc'teryx Sqamish was made with 30d Gossamera fabric without any clear breathable PU coating (CBPU). For 2009 it was made with 30d Gossamera and CBPU coating. From 2010 – 2013 it was made with 20d Luminara and CBPU coating. For 2014 it is made with the 30D Gossamera and a MUCH less substantial CBPU coating, compared to 2013, yielding very different test results.

Neither the fiber nor the weave is the cause of the significant performance differences between the 2013 and 2014 versions; it is primarily caused by the reduced CBPU coating on the 2014 version.
