BD Athlete Hazel Findlay says that Book of Hate (5.13d)—a blank, overhanging corner in Yosemite Valley—is "all in the legs". "Probably the easiest 13d someone like me will ever find," says Hazel, since she self-admittedly loves a good stemming test piece.

We figured that putting Hazel in a pair of our new Forged Denim stretch jeans on Book of Hate would stand as the ultimate test. Can they hold up to the endless "bridging" as Hazel says, on one of the world's hardest corner pitches?

The answer is yes. Hazel, as well as our other athletes have been making the rounds in the Forged Denim and have reported back that these jeans truly rock.

BD Athlete Nalle Hukkataival recently took a pair on a developing spree in the boulder fields of Tuzgle, Argentina, where he wore the denim while sending highballs at 14,000 feet. "Love these new stretchy jeans!" says Nalle. "Never once felt restricted by them while climbing and the fabric is comfy and durable. Something you can wear from a day of climbing to the bar. What's not to like?"


BD’s new Forged Denim uses an innovative combination of best-in-class materials with climbing specific features to create the world’s best climbing denim, utilizing Black Diamond’s exclusive BD.FORGED design protocol. Through this process, we’ve created denim that is both extremely durable, yet unbelievably light and stretchy, designed to work perfectly with your climbing gear.

Fashionable lady crusher Daila Ojeda explains that not only do these jeans climb well, they look good too.

“Comfortable, durable and practical,” says Daila. “You can feel like a climber on the rocks and like a climber at the bar drinking a beer.”

Be prepared to slip into a pair and never want to take them off … at least not for climbing.
