Biggest Hiking Backpacks by Capacity (2026)

Stone Glacier's Sky series tops out at the Sky Guide 7900, a 7,400 ci main bag plus the included 500 ci Sky Lid for a 129 L total, and the successor to the Sky 7400. The $775 price is the complete pack: bag, a Krux, Krux Short or Xcurve frame, an S/M/L belt and the lid, at 5 lb 8.7 oz on the Krux with a medium belt. The bag separates from the frame to open a 2,500+ ci load shelf rated past 150 lb.

Designed with Shoot2Hunt and released in June 2025, the Teratorn 7400 is Exo Mtn Gear's largest pack system, a 7,400 ci (about 121 L) bag. Exo rates it at 150+ lb.

The Terminus 7000 is Stone Glacier's ultralight expedition pack for sheep and goat hunters: 7,000 cubic inches (115 L including the 500 ci lid) at just 3 lb 15 oz, with the bag sewn directly to a 26-inch carbon-stay frame rated for 150+ lb loads. A 2,200 ci collapsible internal load cell positions boned-out meat against the frame, and the main bag compresses to 4,300 ci in bivy mode for day hunts. The main bag uses SG's waterproof ULTRA fabric, a UHMWPE blend developed with Challenge Sailcloth.

The Sky Talus 6900 is Stone Glacier's best-selling, most fully-featured bag: a 6,400 ci main bag plus included 500 ci lid (113 L total) with four external side pockets and a full-length center zip. It converts from a 4,750 ci bivy-mode day pack to an 8,900+ ci expedition hauler with the 2,500+ ci load shelf deployed, all on a 150+ lb-rated Krux or Xcurve frame for $750 complete. Many owners recommend it for Alaska and sheep-hunt duty.

The newest bag in Kifaru's Expedition line, blending the Dall and Kutthroat into a 6,580 ci (108 L) external-frame pack with dual access via a horseshoe zipper and snow collar. Ultragrid and EPX400 fabric makes it the most weatherproof bag in Kifaru's lineup, with integrated pockets that replace add-on belt pouches. Complete system is $877 ($377 bag + $500 25-inch carbon ARK frame) at 6 lb 4 oz.

Kifaru's guide-driven expedition hauler since 2019, updated in Gen 2 form (fall 2025) with a full-length main zipper. Total capacity is 6,500 ci (107 L): a 4,340 ci main bag, 1,000 ci expandable snow collar, and dual 580 ci zippered side pockets sized for spotting scopes. The complete system is $850 ($350 bag + $500 25-inch carbon ARK frame) and weighs 6 lb 7 oz.

The Sky Archer 6400 is Stone Glacier's bowhunting-specific expedition bag: a 5,900 ci main bag plus included 500 ci Sky Lid (6,400 ci / 105 L total) that replaced the Sky Archer 6250. Its signature is a 26-inch side zipper giving full internal access while your bow stays strapped to the front under the integrated storm-flap carry system. The 2024 refresh added an external-access spotting scope pocket, an 8-inch stow pocket, and a 14-inch stretch side pocket, and the complete Krux or Xcurve system runs $750 with a 150+ lb load rating.

Mystery Ranch's largest and most feature-rich expedition hunting pack, rebuilt for 2025 on the MYSTERIUM frame at 103 liters (6,285 cu in). It pairs the patented Overload meat shelf with a bottom speed compartment for a sleeping bag, dual full-length side zips, and a removable lid that converts to a daypack for spike-camp stalks. Built for 10+ day hunts, sheep and moose expeditions, and guide duty.

The Unaweep 6300 is Seek Outside's integrated-platform hauler — 103 liters on the same Revolution frame as the breakaway packs, but with the bag sewn to the suspension for lower weight and a simpler ride. GearJunkie scored it 8.7/10, and it has been used everywhere from Denali's West Buttress at 120 lbs to multi-week packrafting expeditions.

Sitka's flagship backcountry hauler pairs 6,200 ci of total volume with a 6061-T6 aircraft-grade aluminum frame that weighs 6.4 lb yet is rated to carry 150 lb. The primary bag expands from 4,000 to 5,000 cubic inches so an elk quarter can be set on the internal load-hauling shelf without re-rigging straps, and every load-bearing component attaches directly to the frame. Harvest-critical components are finished in Sitka orange so they stay findable during a fatigued pack-out.

The ICON 6 6000 is Kuiu's 2025 ground-up replacement for the Pro 6000, pairing a 98-liter expedition bag with a patent-pending 3D corrugated thermoplastic carbon frame that yields under stress instead of shattering. The $699 full kit ships with the frame, suspension, two hip belts, a load sling, a rifle quick release and a gear loop strap, and at 6 lb 2.4 oz it remains one of the lightest week-long backcountry haulers sold.

Kuiu's first women's frame-pack line, released in June 2026, puts a women's harness and belt on the same USA-made 3D carbon ICON 6 frame as the men's system. The 6000 holds 98 L with its detachable 700 cu in lid and weighs 6 lb 2.4 oz as a full kit; $699 is the complete pack with bag, frame and suspension. It converts to a load-sling mode that carries 5,000 cu in of meat against the frame.

Stone Glacier's do-it-all western pack: a 5,400 ci main bag (5,900 ci / 96 L with the Sky Lid) on a Krux or curved Xcurve carbon-stay frame, rated past 150 lbs yet about 5.1 lbs complete on the Krux. The $725 system compresses to a 4,300 ci bivy-mode day pack and opens a 2,500 ci load shelf between bag and frame for hauling quarters, with USA-made CORDURA 500/X-Pac construction.

Exo's weeklong workhorse: a 5,010 ci bag (5,658 ci / 93 L with the included lid) on the carbon-stay K4 frame rated past 150 lbs, sold as a complete $700 system. It pairs a roll-top plus horseshoe zip with the deepest stock organization in the flagship class, with four frame heights and five hipbelt sizes built in Boise, Idaho.

The Commander + Pack Bag pairs ALPS OutdoorZ's aluminum freighter frame with a detachable 5,250 ci (86 L) ripstop bag, giving budget hunters a true meat-hauling system for a $269.99 list price. Strip the bag off and the frame's lashing system and fold-out shelf carry quarters solo. The torso adjusts from 17 to 23 inches, making it a popular loaner and first elk pack.
