Mystery Ranch Marshall 105 vs Stone Glacier Sky Archer 6400
Quick take: The Stone Glacier Sky Archer 6400 carries more (105 vs 103 liters); the Stone Glacier Sky Archer 6400 is lighter (5.18 vs 6.7 lbs).
Which one to buy
A bow on the front of the pack is the deciding detail. Both packs cost $750 and hold about the same volume. The Stone Glacier Sky Archer 6400 is built around a 26-inch side zipper that reaches the whole bag while your bow stays strapped under its storm flap. Owners who switched from Stone Glacier's Talus 6900 say it ends the routine of unstrapping the bow to get into the pack. It weighs about 1.5 lb less than the Mystery Ranch Marshall 105 and carries a 150+ lb rating, while Mystery Ranch gives none.
The Sky Archer's drawbacks are mostly about extras and availability. The hydration sleeve, hipbelt pockets and organizer pockets cost extra, so a fully set-up bag runs $850 or more. It has few reviews on Stone Glacier's site, and one long-term owner decided he'd rather have more pockets and just unbuckle his bow. Owners also say the side zip and spotter pocket get tight when the bag is stuffed full. Its fabric is PFAS-treated, so it can't ship to California or New York. For rifle hunters, the main feature does nothing.
The Marshall is the better rifle and guide pack. A bottom sleeping-bag compartment, two full-length side zips, rifle or bow carry and four frame sizes with an adjustable yoke are all included. Testers carried two elk quarters plus antlers with no slippage. Its weaknesses are weight, noise (the previous version had squeaky straps and loud fabric in brush), a lid-to-daypack conversion one reviewer never found comfortable, and, as of October 2026, no stock at Mystery Ranch with no restock estimate. Take the bow out of the picture and the Sky Archer's main advantage disappears, leaving its extra-cost accessories and thin track record.
Mystery Ranch Marshall 105
For rifle hunters, guides and expedition hunters who want rifle or bow carry, a sleeping-bag compartment and side zips included, and can live with the weight.
Stone Glacier Sky Archer 6400
Made for backcountry bowhunters on long hunts who want full access with the bow still strapped on, a 150+ lb rating and a lighter frame, and who aren't ordering for delivery to California or New York.

Pros & cons
Mystery Ranch Marshall 105
- ✓This is Mystery Ranch's biggest hunting pack by a wide margin — 103 liters swallows 10+ days of gear, and Outside Bozeman called the attention to detail on 'this 105-liter beast' evident the moment you strap it on.
- ✓Long-term testers load it brutally: Backwoods Pursuit packed two elk quarters plus antlers with 'no slippage' and found no noticeable vertical frame flex, with 60+ lb loads staying comfortable.
- ✓The Overload meat shelf is unusually easy to deploy for a pack this size — reviewers single out the ease of access for getting quarters between frame and bag.
- ✓The dedicated bottom speed compartment keeps a sleeping bag accessible without unpacking, and dual full-length side zippers reach the middle of the enormous main bag — access most expedition top-loaders can't match.
- ✓The removable lid converts to a daypack, so you can drop camp and stalk light from a spike camp without carrying a second pack.
- ✓Outside Bozeman raved about the carry: the five-point hipbelt 'hugs the hips with a secure firmness, while the back panel and load straps pull the weight off the shoulders' — even suggesting you add 15 lbs more than you think you can carry.
- ✓The 2025 MYSTERIUM rebuild cut roughly 0.8 lbs versus the old Guide Light MT Marshall while adding the new weatherproof CORDURA 5PM fabric.
- ✓Owner reviews are a perfect 5.0 at Scheels, with one guide-type user writing 'I trust my life with the Marshall' — and Mystery Ranch's lifetime guarantee backs it.
- ✗At $750 in either colorway it is Mystery Ranch's most expensive hunting pack, priced right against a Stone Glacier Terminus 7000 or Exo K4 7200 without their lighter weight or modular bag swaps.
- ✗At 6.7 lbs it runs about 1.5-2 lbs heavier than comparable Stone Glacier and Exo expedition systems — weight you carry on every mile of a long hunt.
- ✗Noise is the recurring Mystery Ranch gripe: the prior-generation Marshall tester reported squeaky shoulder straps and fabric that's loud brushing through branches on stalks.
- ✗The lid-to-daypack conversion is more clever than comfortable — the Backwoods Pursuit reviewer 'never really found it to be comfortable' as an actual stalking pack.
- ✗External storage is lean for a pack this size — two torpedo pockets and no stock hipbelt pockets, so quick-access items depend on add-on accessories.
- ✗Mystery Ranch publishes no official load rating, leaving buyers to forum anecdotes while Stone Glacier claims a 150 lb spec on its expedition frames.
- ✗As of October 2026 both colorways show out of stock direct from Mystery Ranch with no restock estimate and thin at retail (GOHUNT showing only a couple units), so finding your frame size can take patience.
- ✗Many owners say 103 liters is overkill for most lower-48 hunts — unless you routinely do 5+ day bivy hunts or fly-in trips, a Metcalf or Beartooth carries better and invites less overpacking.
Stone Glacier Sky Archer 6400
- ✓The 26-inch side zipper is the killer feature no competitor matches at this weight: full-height internal access with the bow still strapped to the pack face — owners who switched from the Talus 6900 say it eliminates the unpack-your-bow dance entirely.
- ✓Purpose-built bow carry using the top compression system and integrated storm flap holds the bow tight against the bag, keeping weight centered rather than swinging off one side like universal bow slings on Kifaru or Exo packs.
- ✓At 5 lb 2.8 oz complete on the Krux it is 1.8 oz lighter than the Sky Talus 6900 while carrying nearly identical volume, a spec that got long-time 6900 owners to switch.
- ✓The 2024 refresh directly answered the old 6250's minimalism complaints: external-access spotting scope pocket, 8-inch zippered stow pocket, and 14-inch stretch side pocket for a tripod or Nalgene.
- ✓500 ci Sky Lid is included in the price, unlike the Solo and Col where lids are extra or unsupported — and Bivy Mode compresses the bag to a legitimate 4,000 ci day pack.
- ✓Full 150+ lb load rating with the 2,500+ ci expandable load shelf means one pack covers scouting trips, week-long elk hunts, and the heavy pack-out.
- ✓YKK Aquaguard water-resistant zippers plus X-Pac construction give it the best weather resistance in the Sky line without a rain cover.
- ✓Made in Bozeman with Stone Glacier's lifetime defect warranty, and the bag swaps onto any existing SG frame if you already own a Krux or Xcurve.
- ✗Only 6 reviews at 4.3/5 on stoneglacier.com — the lowest-rated and least-reviewed bag in the current SG lineup, so the redesign has a thin track record compared to the 220-review Sky Talus 6900.
- ✗A multi-year owner concluded 'I'd rather have a few more pockets and just unbuckle my bow' and preferred the Talus 6900's organization — the side-zip advantage matters less than it seems for some hunters.
- ✗Contains PFAS-treated fabric and cannot be shipped to California or New York, an unusual restriction competitors like Exo and Kifaru don't carry.
- ✗Availability has been spotty since the original 6400 launch, with Krux-frame and Xcurve size/color combos often back-ordered.
- ✗Still fundamentally a minimalist single-compartment bag — the Talus 6900 offers four external side pockets at the same $750 for hunters who prioritize organization over bow access.
- ✗Hydration sleeve, Swing-Out Pockets, Camp Pockets, and hipbelt pockets are all sold separately, so a fully rigged bag costs $850+.
- ✗The bow occupies the front of the pack, so rifle hunters get no benefit from the signature feature and are better served by the Sky 5900 or Talus 6900.
- ✗When the bag is stuffed to its full 6,400 ci, owners note the internal spotter pocket and side-zip access get tight — the design shines most at partial loads.
Mystery Ranch Marshall 105 vs Stone Glacier Sky Archer 6400: common questions
Should a rifle hunter consider the Sky Archer 6400 over the Marshall 105?▾
Probably not. The Sky Archer's main feature is reaching into the bag while a bow stays strapped to the front, which does nothing for rifle hunters. The Marshall includes rifle or bow carry, a bottom sleeping-bag compartment and two full-length side zips at the same $750.
Which pack carries heavy meat loads better?▾
Stone Glacier rates the Sky Archer at 150+ lb on a 2,500+ ci expandable shelf. Mystery Ranch offers no rating, but testers carried two elk quarters plus antlers in the Marshall with no slippage or noticeable frame flex. Both work for heavy hauls, and only the Sky Archer has a rating to go by.
What does the Sky Archer 6400 really cost once it's set up?▾
A fully set-up bag runs $850 or more, because the hydration sleeve, hipbelt pockets, Swing-Out Pockets and Camp Pockets are sold separately. The 500 ci Sky Lid is included. The Marshall includes a hydration sleeve but also lacks hipbelt pockets.
