The Brass Zipper Ascent

That heavy canvas backpack resting by the hallway closet was practically daring me to lock down its main compartment! The chunky brass zipper pull hung halfway down the seam like a suspended climbing harness. No hesitation! I grabbed the cool metal tab with both hands, planted my boots against the stiff ribbed canvas, and heaved with everything I had! SKRRR-CLACK! The metal teeth zipped shut one by one beneath my feet, buzzing straight through my arms with every click! Step by step, I hauled the slider all the way to the top seam until—SNAP! Locked tight at the summit! Flawless heavy-duty ascent!
