I have a Zpacks Nero available for sale. It is in near perfect condition, only used a few times. It is the green version and sizing is adjustable to fit different size torsos.

The manufacturer says: “The Nero is a compact frameless backpack streamlined to only the most essential features making it great for hikes where less weight and volume is required.

Multiple thru-hikes of the Triple Crown trails have been completed with our Nero series backpacks, helping to prove that smaller volume frameless packs are a legitimate approach to long-distance hiking.

Featuring an optional removable belt, an included sit pad, and a variety of optional modular add-ons, the highly versatile Nero Ultra will allow you to get the most out of any day, section, or thru-hike.”

Price does not include shipping.
