Cirque Ultra 35L Backpack

What Our Gearhead® Experts Are Saying:

"I love how this pack balances durability with minimal weight. The roll-top closure is quick to use with gloves on, and the avy tool pocket keeps gear ready when I need it fast. The diagonal ski carry is super secure for bootpacks, and I appreciate that I can strip the waist belt and frame sheet when I want to cut down on weight for faster missions."
