ULA Equipment Circuit SV

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.

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.
