Since 2016, Outdoor Research's proprietary AscentShell™ technology uses an electrospinning process to create a 3L construction that breathes faster, weighs less, stretches more, and far surpasses the comfort of traditional waterproof membranes. Never crunchy or noisy, AscentShell™ is just as comfortable as a soft shell, with the performance of a hard shell. Air permeable and breathable, AscentShell™ vents perspiration and excess heat during aerobic activity, while its light weight saves precious energy on demanding endeavors.

Comfort, protection, and enhanced freedom of movement are exactly what first-of-its-kind GORE-TEX Fabric with Stretch Technology aims to deliver. Combining the trusted waterproof durability that GORE-TEX is known for, with waterproof stretch panels that let you move freely, this technology is the best way to prioritize comfort without compromising protection. GORE-TEX Fabric with Stretch Technology can just as easily move with you as a second base layer, or accommodate extra insulation as the stretch panels expand to allow you more room.

The new GORE-TEX INFINIUM with WINDSTOPPER provides protection against wind chill by using a totally windproof membrane with maximized breathability, allowing perspiration to escape and reduces the risk of overheating when active. INFINIUM with WINDSTOPPER is created using an ultra-thin protective layer laminated to a lightweight textile, rendering the product windproof. Its membrane technology has billions of pores that are 900 times larger than water vapor molecules, so even though wind can't get in, moisture from sweat vapor can easily get out.

Pertex developed Diamond Fuse technology as a unique way of improving the durability and abrasion resistance of fabrics without adding any unnecessary weight. Diamond Fuse fabrics use yarns with unique diamond shaped filaments that lock together to create a durable and highly abrasion resistant fabric. This engineered structure allows Diamond Fuse fabrics to remain very stable over extended wear and washing.

Providing a waterproof barrier against rain, snow, and wind in tough, hardworking, rugged environments, Ventia Waterproof™ construction ensures moisture from the outside won't penetrate fabric. Breathability allows body vapor and moisture that builds during active pursuits to escape for greater warmth and comfort. With seam-taping for the most thorough protection, this proprietary technology provides storm-worthy protection for active use in rugged, demanding conditions.

Deadening cold is no match for the innovative breakthrough of PrimaLoft® Gold Insulation Aerogel. Optimally designed for footwear and handwear applications, Aerogel insulation is a compression-resistant and waterproof thermal barrier made up of millions of air pockets that reduce heat loss from freezing cold elements. Aerogel is trusted by NASA space travel and retains on average 96% of its original thermal performance when faced with the pressure caused by active hands and feet.

Outdoor Research proprietary Ferrosi Fabric makes up our largest, and most frequently awarded, product collection.

Ferrosi is truly the “do-it-all” choice for any adventurer looking for a layer that ticks three or more items off the gear list.

Outdoor Research proprietary Astroman Fabric is a catch-all for the adventurer who spends extended time in sun-baked environments.

Lightweight, stretchy, and silky-soft, the Astroman is comfortable for all-day wear, while retaining an extreme level of durability for brushes with rock while climbing.

Outdoor Research proprietary Echo Fabric is the all-time best-selling choice for ultralight protection during high-exertion activities in heat. Each Echo product is infused with UPF 15 sun protection to fight off dangerous UV rays, and ActiveFresh™ odor control technology to repel bad smells.

AirVent pulls perspiration away from the skin as you sweat for outstanding moisture management that dries quickly without sacrificing durability.
