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.
Don't be a jerk, ride with the Zerk. Its Duzer approved and he's a really nice guy.
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. Increase the carry functionality by taking advantage of compatibility with ourZerk 3L Loki Lumbar pack which acts as a chest rig on the Zerk 13 shoulder straps!

Finally found a replacement for my 15 year old pack!
So many pockets! The pack is very comfortable to ride and hike with. I’m not a fan of hip belts when riding, but this one works great; it positions the pack weight where it needs to be. I forget I’m wearing it. Each element of the pack was very well thought out.

room and accessibilty for ALL of your on board burritos (and water)
amazing room for multiple burritos and the correct amount of water to be lugging on your back while pushing pedals around the map. love the securness (its a word now) of the three clip straps, the depth of the shoulder strap pockets going vertically down the torso and how handy the flank pockets are at the bottom of the shoulder straps. The magnet to hold the water hose is a complete game changer. no more fighting with the ridiculous clip that played a part in my last wreck. I cannot recommend this backpack enough for getting out there!!!
