I've been very disappointed with the primaloft filled clothing that I have tried.
IMO - for synthetics, I've found polarguard delta and climashield clothing both offer vastly superior performance.
Primaloft seems to go very thin and loses its loft in no time. It also doesn't have any 'guts' and gets completely flattened by any strong wind. In the garments I've tried, this reduces them to the effectiveness of a pertex windshell or similar with little significant insulation/thermal property to speak of.
Guess I'm not a huge fan then huh??
