What is PrimaLoft®?
From active insulation that adapts to your body’s output to loose-fill insulation that mimics the structure of down, we use a variety of PrimaLoft synthetic insulations in our gear.
Active Insulation
PrimaLoft® Active Evolve comes in varying thicknesses and lengths, creating highs and lows within the loft. This design traps warm air while allowing excess heat to escape.
Static Sheet Insulation
PrimaLoft® Gold Insulation with Cross Core blends aerogel for ultra-lightweight warmth and compressibility, delivering comfort in harsh conditions.
Loose Fill Insulation
PrimaLoft® Silver Insulation is made from 100% recycled materials and engineered to mimic down, offering exceptional loft and warmth.
