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.

Features

Pros

  • βœ“ULA publishes a specific 25 lb maximum load, which most cottage brands leave unstated.
  • βœ“Four torso sizes from 15 to 24+ inches is far more sizing granularity than most frameless packs offer.
  • βœ“UltraGrid is a doubled 200D recycled grid, notably tougher than single-layer gridstop.
  • βœ“$200 is the cheapest ULA pack and undercuts most cottage frameless packs.
  • βœ“50 L is generous for a frameless pack, handling a bear canister at a push.
  • βœ“27.1 oz is competitive with framed packs 10 L smaller.
  • βœ“UltraStretch front pocket holds shape better than plain mesh.
  • βœ“ULA's sizing guidance explicitly covers what to do when between sizes, which is unusually careful.

Cons

  • βœ—25 lb is a hard ceiling and easy to exceed with water and several days of food.
  • βœ—Frameless construction puts the whole load on the shoulders once the pad is compressed.
  • βœ—No adjustable torso; the size must be right at purchase.
  • βœ—ULA lead times fluctuate significantly with seasonal demand.
  • βœ—No hydration sleeve as standard.
  • βœ—50 L invites overpacking past what a frameless pack can carry.
  • βœ—Warranty terms are not published in the way major brands publish them.
  • βœ—Limited retail presence, so trying one on before buying is unlikely.

ULA Circuit

The Circuit is the thru-hiking pack β€” 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.

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.
