The Nero Ultra 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.

I’m on the Application Trail right now for the last 30 days and am 100% happy so far. Awesome pack. Probably best on trail.

Comfortably transfer your pack’s weight to your hips with our custom Curved Carbon Fiber frame system. The frame also creates a gap between your back and the pack allowing for air flow that helps keeps you cool.

This is absolutely perfect. Ease of loading and unloading along with typical Zpacks quality. Fits great and weighs nothing.
