Zpacks Arc Haul Ultra 60
The Arc Haul Ultra 60 is Zpacks' engineering statement: a 21.7-ounce pack whose carbon arc frame tensions a mesh panel off your back — the only true ventilation in the sub-1.5-lb class. Backpacker magazine named it the best ultralight pack of 2026.
Specifications
Features
Pros
- ✓The lightest framed, ventilated 60L pack money can buy — nothing else combines 21.7 oz with a real airflow gap.
- ✓Backpacker magazine's best ultralight pack of 2026, adding mainstream validation to years of thru-hiker use.
- ✓The tensioned arc genuinely works: sweat reports drop dramatically versus foam-back cottage rivals.
- ✓Ultra 100X fabric is waterproof and far more abrasion-resistant than the old DCF packs.
- ✓The user-adjustable frame height effectively customizes torso length — rare in the cottage world.
- ✓Carries 35-40 lbs shockingly well for its weight, per repeated long-trail reviews.
- ✓Modular add-on ecosystem (belt pouches, shoulder pockets, lumbar pads) lets owners spec it like a custom pack.
- ✓Zpacks' repair department keeps long-trail packs alive mid-hike with fast turnarounds.
Cons
- ✗Early Ultra-fabric generations had documented delamination reports; Zpacks revised the laminate, but the history follows the brand on Reddit.
- ✗$399 plus the add-ons most people want pushes real cost toward $475.
- ✗The arc frame takes fiddling to tension right, and a mis-set arc pokes the lumbar.
- ✗The 2-year warranty is thin next to ULA's and Osprey's lifetime coverage.
- ✗The curved frame reduces usable volume and makes tall canisters ride oddly.
- ✗No hydration sleeve — bottle-only hydration is assumed.
- ✗Mesh and edge trim wear faster than the body fabric; brush country is not its habitat.
- ✗The whole design rewards careful owners and punishes casual abuse — it's precision gear, not a rental mule.
