ULA Equipment Ultra Circuit

The Ultra Circuit is the Ultra-fabric version of ULA's best-known pack. It keeps the Circuit's carbon hoop and aluminium stay combination but rebuilds it in Ultra 400X and 200X, making it waterproof and considerably more tear-resistant than the standard Robic version.

Pros

  • 68 L is the largest capacity in this ultralight group and handles a bear canister plus a week of food.
  • The carbon hoop and aluminium stay combination is a proven load-transfer design across many Circuit generations.
  • Ultra 400X on the body puts the heaviest laminate where abrasion happens.
  • Waterproof laminate rather than a coated weave.
  • ULA's sizing system is unusually thorough for a cottage brand.
  • Rated for heavier loads than most packs of this weight, which is the Circuit's long-standing reputation.
  • 35.9 oz for 68 L is a strong ratio given the frame hardware.
  • Hipbelt pockets included.

Cons

  • $380 is a significant premium over the standard Circuit at around $300.
  • 35.9 oz is the second-heaviest pack in this comparison group.
  • Ultra laminates are difficult to field-repair.
  • No published maximum load figure despite the pack's load-hauling reputation.
  • No adjustable torso; sizing must be right at purchase.
  • ULA lead times fluctuate with demand.
  • 68 L invites overpacking, which defeats the purpose of an ultralight pack.
  • Limited retail presence for in-person fitting.

ULA Equipment

ULA Circuit

The Circuit is the thru-hiking pack — hand-made in Logan, Utah by ULA Equipment and a perennial #1 in Halfway Anywhere's PCT gear survey. Its 68 liters of total volume, bombproof Robic fabric, and 35 lb carry make it the default recommendation for first thru-hikes. An Ultra-fabric version is sold at a premium.

ULA Equipment CDT

The CDT is the largest of ULA's frameless packs and the cheapest way into the brand. UltraGrid is a doubled 200D recycled grid fabric that resists tears well beyond its weight, and ULA states a clear 25 lb ceiling rather than leaving it to inference.
