ACTIVITY: Rock/Ice/Alpine Climgin; High Output Activities

The Proton LT Hoody is Arc’teryx’s most durable, insulated jacket to date. After many iterations and countless wear tests to finely tune the balance of performance and durability, the designers ended up with a fabric that is proven to be over 60x more durable in abrasion tests than the industry standard.

Highly breathable, the Hoody is a synthetic midlayer for high-output activities. “We designed the Proton LT for our core user who will put it to extremes from climbing to snowsports, so our biggest challenge was creating a textile that was light and open enough to be air permeable, but tough enough for multiple end use,” says designer Brylee Geddis. “Advanced material technology allowed us to create Fortius™ Air 20 face fabric. It has outstanding hardwearing durability as well as high air permeability. The result is my go-to jacket whether I’m going climbing, skiing, or backpacking, I’m stoked to have it!”

But innovation didn’t stop there. Inside, the Proton LT  has Coreloft™ Compact 80 synthetic insulation that, paired with the  Fortius™ Air 20 face fabric, creates a solid balance between air permeability and thermal protection. Other key features like the Hemlock drawcord and helmet compatible hood allow for essential climbing gear to work seamlessly with the Proton LT Hoody. Versatile, durable and breathable; a best in class blend which unlocks a range of high output activities that will let you go further.
