PrimaLoft®

PrimaLoft®: Lightweight Warmth. No Compromise.

When the temperature drops, PrimaLoft® steps up. Built from ultra-fine fibres—thinner than human hair—it delivers serious warmth without the weight or bulk.

Originally developed for the US military, it’s engineered to perform in tough conditions. Today, it goes further—combining durability, comfort and a more sustainable approach using recycled materials.

Soft, packable and ready for anything, PrimaLoft® is made to move with you.

Whether you’re pushing the pace or heading out into the cold, it balances warmth and breathability. Air flows freely through the fibres, allowing excess heat and moisture to escape—so you stay comfortable, not clammy.

And unlike traditional insulation, it keeps performing even when damp.

Why it matters:

• Lightweight warmth without bulk
• Breathable design to regulate temperature
• Water-resistant fibres that perform in damp conditions
• Made using recycled materials for a lower impact

From fast-moving hikes to everyday wear, PrimaLoft® delivers reliable warmth you can depend on—wherever you’re headed.
