Why PrimaLoft?
Treks in subfreezing climates threaten to push the average body temperature to dangerous levels. Combat the cold with PrimaLoft fabrics which form tiny air pockets that trap body heat and keep the elements out—even in rain and snow.
How Does It Work?
Water resistance, engineered. Ultrafine fibers create surface tension that prevents moisture from penetrating the garment, while also allowing vapor to escape for breathability.

PrimaLoft Black Insulation ECO
High-performance insulation meets post-consumer recycled content. Over 266 million plastic bottles have been

To Sum It Up
Whether you’re flying down a steep run or the temps suddenly plunge in the backwoods, our winter gear with PrimaLoft’s synthetic insulation keeps you warm. Its lightweight construction provides the optimal blend of protection and compressibility, plus stands up to any rain and snow you encounter on your outdoor adventures (something natural down jackets can’t do). Originally built for the army and now in the packs of climbers, skiers, and alpine explorers everywhere, PrimaLoft also offers an environmentally friendly line that’s diverted 266 million plastic bottles from landfills.
