ULA Equipment Circuit (68L)

Published · Researched 2026-09-21

2026 lineup note: Current and effectively unchanged for over a decade — ULA Equipment (Logan, Utah) iterates rather than redesigns: the 2024 update brought the UltraStretch front pocket and an Ultra-400 fabric option (the "Ultra Circuit"). Still the best-selling cottage thru-hiking pack in North America at $300 (Robic version).

Version lineage (2023–2026)

• 2001–present: Circuit (continuous) — Brian Frankle's original ULA pack, in production since ULA's founding. A living design: small running changes (pocket fabrics, strap options) but never a generation break.
• 2024: UltraStretch front pocket update — the front mesh pocket switched to a stretchier, more durable mesh; ULA introduced the Ultra-400 fabric option (~$365–400, ~1.5 oz lighter) alongside standard Robic.
• 2025–2026: Continued; the Circuit remains ULA's best seller and the most-used pack in Halfway Anywhere's annual PCT hiker survey for multiple years running.
• Still a smart buy? There's no "old Circuit" to avoid — any used Circuit from the last decade is the same pack. Buy used ($200–225) with confidence; the only decision is Robic vs Ultra fabric.

Overview

The Circuit is the thru-hiker's workhorse: 68 L total (4,200 cu in), a 35-lb comfort ceiling that embarrasses most packs under 2.5 lb, and a three-part suspension (carbon-fiber + Delrin hoop, foam framesheet, single aluminum stay) that gives it real structure where frameless packs flop. ULA 400D Robic nylon is the standard fabric — tough enough that PCT thru-hikers routinely finish the trail on one pack. Fit is made-to-order: three torso sizes, six hipbelt sizes, J- or S-shaped shoulder straps. Roll-top closure with side compression, dual hipbelt pockets, front shock cord, ice-axe/pole loops, and a hydration sleeve. Every bear canister on the market fits vertically. Made in Utah, USA.

Key Specs

Pricing

• MSRP: $300 (Robic) — packstack review data (Sept 2026) and CleverHiker (2025) both cite $300; Ultra-400 version ~$365–400.
• Street price: ULA sells direct; no MAP games — $300 is the price. Used: $200–225 (GearTrade/Shoppok listings, Sept 2026).

In the Box

Pack (built to your torso/belt/strap spec). Optional accessories (shoulder-strap pocket, hydration sleeve, handloops, internal stash pocket — a $76 value on older listings) are not included by default. Rain cover not included (ULA sells one separately).

Warranty

ULA Equipment lifetime warranty against manufacturing defects — exact current terms UNVERIFIED from today's research (packstack's review table cites "Lifetime"; re-verify at ula-equipment.com).

Support & Parts

ULA's small Utah shop does repairs directly — strap, hipbelt, and buckle replacements are the routine work. Because the pack is made to order, fit parts (hipbelts in 6 sizes) are always in stock. Turnaround is personal but small-shop slow in spring thru-hiker season.

Community Verdict

The Circuit is the most-copied, most-recommended thru-hiking pack in North America — Halfway Anywhere's annual PCT survey has named it the most-used pack for years running, and BPL/r/Ultralight treat it as the default answer to "my frameless pack isn't carrying 30 lb." CleverHiker (4.6/5) calls it the "Best Load-Hauling Ultralight Backpack": stable and comfortable to 34.5 lb in their Rocky Mountain testing, with the honest cons that it's "too big for some" and the Robic needs DWR upkeep for water resistance. The two recurring owner complaints: the back panel isn't ventilated (sweaty backs in summer) and the shoulder straps could use more padding near max load. No fabricated scores.

Research date: 2026-09-20. Specs from packstack-tech's ULA Circuit review (Sept 2026: 1,092 g, 68 L, 35-lb max, $300, lifetime warranty), CleverHiker's review ($300, 2 lb 6.5 oz, 4.6/5), and GearTrade's used-Circuit listings. Used pricing from Sept 2026 listings. Image 1 shows the embroidered "ULA CIRCUIT" logo; images 2–3 match the Circuit's green Robic/black colorway and yellow hardware.

Long-term durability & warranty-claim reality (enrichment — Sept 2026)

The Circuit's durability is trail-proven at scale: full-PCT finishes on a single pack are routine, and the 400D Robic shows the PCT-survey longevity that made ULA's reputation. The known long-term wear points: the front mesh pocket (pre-2024 generations; the UltraStretch update addresses this), and hipbelt foam compression after thousands of miles. Warranty-claim reality: ULA is a small shop that repairs rather than replaces — owners report reasonable, personal service but spring-season backlogs. The secondhand market is so deep that parts packs are always available.

Version history — year by year (enrichment — Sept 2026)

• 2023: Circuit unchanged (Robic standard).
• 2024: UltraStretch front pocket; Ultra-400 fabric option introduced ("Ultra Circuit").
• 2025: Continued; top of Halfway Anywhere's PCT pack survey again.
• 2026: Continued at $300 Robic. No redesign announced — ULA's model is continuous iteration.

Head-to-head vs closest rivals (enrichment — Sept 2026)

• vs Osprey Exos Pro 55 (/library/gear/water-packs/osprey-exos-pro-55/ — new this round): the Circuit hauls 5 lb more and costs $20 less, but has no ventilated back and no big-brand warranty. Sweaty-back hikers → Exos Pro; load-haulers and cottage-loyalists → Circuit.
• vs Gossamer Gear Mariposa 60 (/library/gear/water-packs/gossamer-gear-mariposa-60/): the Mariposa is the organized pick (7 pockets, $315); the Circuit is the hauling pick (35-lb ceiling, made-to-order fit). The two most-argued packs on r/Ultralight.
• vs Hyperlite Mountain Gear Southwest 55 (/library/gear/water-packs/hyperlite-mountain-gear-3400-southwest/): HMG is waterproof and lighter; the Circuit is cheaper, more adjustable, and has a real frame. Weather-proofing vs structure.

Care & maintenance (enrichment — Sept 2026)

Robic nylon is not waterproof — maintain the DWR with periodic spray-on treatment and always use a pack liner or cover in sustained rain. The roll-top's side compression straps are the abrasion point against rock; inspect stitching annually. Wash the hipbelt to prevent salt-crystal abrasion of the foam. Store uncompressed.

Buying traps (enrichment — Sept 2026)

• "Circuit" is also a model name other brands use — verify the ULA logo/made-in-Utah tag; the embroidered mountain logo on the front pocket is the tell.
• Old accessories (pre-2020 shoulder-strap pocket, internal hoop) are sometimes listed as "included" — they're optional extras, not standard.
• The 68 L includes all pockets — the main bag is smaller than a traditional 68L; size up your expectations, not the pack.

Community Verdict — additional voices (enrichment — Sept 2026)

Additional sourced voices (Sept 2026): CleverHiker — "Best Load-Hauling Ultralight Backpack," comfortable to 34.5 lb in testing; a Shoppok seller listing (Sept 2026) itemizes the Circuit's thru-hiker bona fides ("most popular pack on the PCT for the past 3 years per Halfway Anywhere"); packstack's review (Sept 2026) — "most popular pack on the Pacific Crest Trail for four consecutive years." No fabricated scores.

Key Specs gap-fill (enrichment — Sept 2026)
