For cold, persistently wet conditions, synthetic insulation remains the only choice for those operating in the most serious environments. Impervious to water, synthetic insulation will maintain warmth even whilst wet and dry quickly, essential attributes for belay jackets and mid-layers that will be regularly exposed to high levels of moisture from the elements or from inside your layers whilst working hard.
is one of the highest performing insulation on the market for warmth, water resistance, softness and compressibility. PrimaLoft® GOLD an ultra-fine microfiber insulation that is as warm, soft and lightweight, and is warmer wet or dry than all other insulations. Ultra-fine fibers form tiny air pockets that trap body heat and keep the cold out. The result is immediate warmth without the bulk. PrimaLoft® GOLD Microfibers are engineered for permanent water resistance and create tight surface tension that resists moisture penetration, resulting in an insulation that dries faster than goose down. Ultra-fine fibers mimic the compressibility of goose down and are breathable, allowing moisture vapor to be transported through the fibers and away from the skin.
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.
