red primaloft logo

High-performance sustainable insulation

Developed in the 1980s for the U.S. Army, PrimaLoft® was created as a water-resistant alternative to down insulation. Today, it's a global leader in synthetic insulation technologies—known for delivering exceptional warmth, compressibility, and performance in wet conditions. Lightweight, breathable, and often made with recycled materials, PrimaLoft keeps you warm and comfortable across a wide range of outdoor pursuits, without compromising on sustainability.

Lightweight, compressible, synthetic insulation

Designed to be lightweight and packable and deliver reliable warmth even when wet while reducing environmental impacts.

MATERIALS WE USE

PrimaLoft® P.U.R.E.™

PrimaLoft® P.U.R.E.™ (Produced Using Reduced Emissions) Insulation sets a new standard of renewable manufacturing technology. P.U.R.E.™ uses 100% recycled polyester and a disruptive manufacturing technology that drastically reduces carbon emissions.

PrimaLoft® Gold insulation with Cross Core™

Created by fusing NASA developed Aerogel particles (composed of 95% air) with the superior warmth and packability of PrimaLoft® Gold fibers. Reaching new levels of warmth this insulation provides in excess of 50% more warmth compared to traditional PrimaLoft® Gold Insulation.

PrimaLoft® Active Evolve

Featuring breathability, moisture management, and stretch, PrimaLoft® Active Evolve was developed to keep you comfortable in a wide range of activities, regardless of intensity or season.

PrimaLoft® Silver

For instances requiring warmth, especially in cold and wet conditions, PrimaLoft® Silver Insulation is a go-to for technical performance. PrimaLoft® Silver Insulation is designed for durability in a lightweight design for active applications, packability, breathability, and softness.

PrimaLoft® Silver P.U.R.E.™

The superior characteristics of PrimaLoft® Silver P.U.R.E.™ insulation offers warmth without bulk and is soft, packable, and lightweight, mimicking the compression of down. Its ultra-fine fibers are water resistant and breathable, allowing moisture vapor to be transported away from the skin ensuring a drier, more comfortable experience.

PrimaLoft® P.U.R.E.™ manufacturing technology transforms the manufacturing of synthetic insulation to drastically reduce the carbon emissions produced during the process. This transformation results in a 70% reduction in carbon emissions during the production of PrimaLoft® Silver Insulation. Ultra-soft fibers deliver uncompromised warmth, loft and packability. A proprietary, water-repellent finish delivers excellent warmth, even in wet conditions.

PrimaLoft® Gold with Cross Core™

PrimaLoft® Gold insulation with Cross Core™ technology fuses NASA developed Aerogel particles (composed of 95% air) with the superior warmth and packability of PrimaLoft® Gold fibers. Reaching new levels of warmth this insulation provides in excess of 50% more warmth compared to traditional PrimaLoft® Gold Insulation.

Originally developed by NASA for use in aeronautical applications. Aerogel is composed of more than 95% air and is the lightest solid material known to man. Silica aerogel forms a temperature barrier – locking out cold and heat. Cross Core™ is composed of multiple PrimaLoft® technologies fused to create next-level comfort and performance.
