Pros & cons

Zpacks Nero Classic 40

  • 9.9 oz is the lightest hiking pack in this entire catalog, lighter even than the Cotopaxi Batac.
  • Ultra 100X with taped seams is genuinely waterproof, not merely treated.
  • Three volumes from 30 to 50 L on the same frameless design.
  • $239 is reasonable for a laminate pack from an established maker.
  • Zpacks has one of the longest DCF and Ultra track records in the segment.
  • Nothing rigid to break, bend or rattle.
  • 40 L is workable for a genuinely light multi-day kit.
  • Hipbelt pockets included despite the minimal design.
  • Frameless at 40 L demands a very low base weight to carry tolerably.
  • No published maximum load figure.
  • Ultra 100X is the thinnest of the Ultra family and abrades at fold lines.
  • No adjustable torso.
  • Difficult and expensive to repair in the field.
  • Sub-10 oz construction leaves no margin for rough handling.
  • Bear canisters do not fit sensibly in a frameless 40 L pack.
  • Warranty terms are not published in the way major brands publish them.

Zpacks Nero Pro 40

  • 11.1 oz is still extraordinarily light for a waterproof 40 L pack.
  • More robust construction than the Nero Classic for only 1.2 oz more.
  • Waterproof taped seams throughout.
  • Same three-volume range as the Classic, from 30 to 50 L.
  • Zpacks' Ultra fabric expertise is among the deepest in the segment.
  • Frameless simplicity with nothing rigid to fail.
  • A sensible middle step between the Nero Classic and the framed Arc Haul.
  • Hipbelt pockets included.
  • $279 is $40 over the Classic for a modest durability gain.
  • Still frameless, so the load rides on the shoulders above roughly 20 lb.
  • No published maximum load figure.
  • No adjustable torso.
  • Laminate fabrics are hard to field-repair.
  • The Classic-versus-Pro distinction is not well explained in Zpacks' own materials.
  • Bear canisters do not fit sensibly at this volume and construction.
  • Warranty terms are not published in detail.
