ULA Circuit

Pros

• Excellent weight transfer to hips, even with loads approaching 35 lbs.
• Accommodates large bear canisters (like the BV500) vertically with ease.
• Highly durable and capable of lasting through full thru-hikes.
• S-strap options and XS sizing provide a good fit for female hikers and those with shorter torsos.
• Responsive and helpful customer service for repairs and updates.

Cons

• Heavier and bulkier than many modern ultralight or frameless alternatives.
• Back padding can cause rubbing or irritation on the spine and tailbone for some users.
• Load lifter attachment points may feel too narrow for hikers with wide shoulders.
• Hip belt padding may be insufficient for users who prefer more cushion.

Caveats

• Pack fit is highly subjective; users often compare it closely with the Durston Kakwa or Z-Packs Arc Haul before deciding.
• The 68L total capacity is often considered overkill for short weekend trips.
• Some hikers find it a 'gateway' pack, eventually transitioning to lighter, frameless options as their base weight drops.

Best for

• Thru-hikers on the PCT or CDT needing to carry bear cans and heavy water loads.
• Hikers transitioning from heavy traditional packs (like the Osprey Atmos) to a lighter setup.
• Users who prioritize load-carrying comfort and durability over absolute minimum weight.

Avoid if

• You have very wide shoulders, as the load lifters may pull at an uncomfortable angle.
• You primarily do short weekend trips where a 35-40L pack would suffice.
• You are a minimalist 'weight weenie' seeking the lightest possible frameless bag.
