Co-designed with Ryan Van Duzer, the new ZERK 13 pack stands alone as the ideal combination of lightweight durability, comfort, and accessibility. Lightweight, body hugging and compact; perfect for fast and committed multi-sport adventures.
From Ryan's DuzerTV website:
I'm a born and bred mountain boy from the foothills of the Rockies. Ever since I was a kid, I've loved playing in the dirt and exploring the great outdoors. My passion is getting people motivated to challenge themselves, all while making this world a kinder place.
Co-designed with Ryan Van Duzer, a prominent long distance bike packer and cycling powerhouse, this ultralight multi-sport hydration pack was developed with one mission; to go to the ends of the earth faster, further, and lighter; all while staying organized with the essentials and hydrated with the included 2L hydration bladder. Utilizing High Tenacity ROBIC Nylon with super durable Ultra High Molecular Weight Polyethylene (UHMWPE) ripstop, the Zerk 13 liter pack will be your best friend and greatest asset for whenever your adventures find you on two wheels or two feet.
