PrimaLoft® One and PrimaLoft® SynergyGram for gram, PrimaLoft® Gold is the warmest, highest performing synthetic insulator used by Simms, retaining 90% of its insulating ability when wet, better than any other insulator on the market today. A close second is PrimaLoft® Synergy, a bit lower in cost, it still has excellent insulating ability when wet, plus a high loft. Both are as compressible and soft as down. |
