Features

Hipbelt Pockets

Pros

  • ✓18 oz stripped is light for a 40 L pack with a hipbelt.
  • ✓Large hipbelt pockets sized for current phones.
  • ✓Challenge UltraGrid is a reinforced fabric that holds up to brush.
  • ✓$219.99 is modest for a cottage frameless pack.
  • ✓Venom Mesh pockets are stretchier and tougher than standard mesh.

Cons

  • ✗Frameless, so comfort fades quickly above 25 lb.
  • ✗Only one colour offered.
  • ✗Weight varies by 3.5 oz with configuration, so listed weights need reading carefully.
  • ✗No adjustable torso or ventilated back.

ULA Equipment

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.

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 Circuit SV
~$299.99
Ultralight Pack

ULA's new smaller-volume Circuit is the Circuit SV: 48 L instead of 68, on the same hoop, foam and stay suspension, at the same $299.99. It weighs 37.5 oz and keeps the 35 lb rating, so the cut is in volume rather than carrying ability.

The Catalyst is the Circuit's bigger sibling — 75 liters of total volume and a 40 lb rating for long food carries, winter kit, or bear-canister-plus-packraft loads. It's the UL pack for people whose trips outgrow the Circuit.

ULA Equipment Ultra Circuit
~$379.99
Ultralight Pack

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.
