PrimaLoft® SYNERGY, is an advanced multi-denier continuous filament insulation engineered for superior warmth, softness and loft. PrimaLoft® SYNERGY is constructed of both fine and ultra fine denier continuous filament fibers. This fiber composition results in an insulation that raises the performance bar of continuous filament insulations.Fine and ultra-fine fibers form tiny air pockets that trap body heat and keep the cold out. These fine and ultra-fine fibers are engineered for permanent water resistance and create tight surface tension that resists moisture penetration. The ultra-fine continuous filament fibers allow PrimaLoft® SYNERGY to be softer and more compressible.

I wore these pants under my waders on a recent B.C. steelhead trip. They kept me very warm better than anything else I have used in past. Only complaint is that the snap on the pants broke on the very first day. I called Stillwater fly shop,told them what happened and they replaced them with a new pair ,great customer service.
