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 ($800 in OPTIFADE Subalpine) 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 mid-2026 it is backorder-only direct from Mystery Ranch and thin at retail (GOHUNT showing only a couple units), so finding your frame size can take patience.
- ✗Forum consensus is that 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.
Mystery Ranch Beartooth 85
- ✓The 270-degree duffel-style zipper is the pack's calling card — owners and reviewers alike say loading and finding gear beats digging through the roll-top-only Metcalf, Stone Glacier, or Kifaru bags from the top, side, or bottom.
- ✓The patented Overload shelf captures quarters between frame and bag with quick-attach autolock straps, keeping meat tight to your back without bloodying the pack interior.
- ✓The new MYSTERIUM frame carries forward the Guide Light lineage Mystery Ranch built its load-hauling reputation on; an early GOHUNT reviewer reported 70 lb loads riding comfortably.
- ✓The split dual-compartment removable lid draws specific praise — the center split stops the lid from compressing your quick-access items and makes headlamps and water filters easy to grab.
- ✓Hunt Talk users consistently favor the Beartooth over the Metcalf for versatility — it compresses down to a legitimate day pack, and one GOHUNT owner said it 'compresses to a sleeker profile than smaller Mystery Ranch packs'.
- ✓Organization is a step above bag-and-frame rivals: internal mesh pockets, front organizational pockets, and MOLLE webbing for customization out of the box.
- ✓Four frame sizes plus an adjustable yoke and a dedicated women's version cover a wider fit range than most one-frame competitors, backed by Mystery Ranch's lifetime guarantee.
- ✓Early Mysterium-line reception has been strong — the Beartooth 85 took Hunt Alaska's Editor's Choice 2026 for hunting packs, and prototype testers in 2024 reported positive results.
- ✗The most repeated gripe carried over from the Beartooth 80: you have to unclip several compression buckles before the 270-degree zipper will actually open, which gets old for quick gear grabs.
- ✗At 6.2 lbs it is one of the heaviest packs in its class — roughly 1.5 lbs more than a Stone Glacier Sky 5900 system and nearly a pound over Mystery Ranch's own Metcalf 75.
- ✗At $650 ($700 in OPTIFADE Subalpine) it costs $75-125 more than the Metcalf, and Rokslide value threads have long questioned the Beartooth premium over the simpler pack.
- ✗Reviewers of the outgoing Beartooth 80 found the load shelf sits too low on the frame, letting lighter meat loads ride below the ideal carry position — an area to watch on the new frame.
- ✗The same long-term testing found comfort degrading around 80+ lbs with loads sliding down the back — hunters routinely packing 100 lb loads still gravitate to Kifaru or Stone Glacier frames.
- ✗No hipbelt pockets come stock; Mystery Ranch sells them as add-on accessories while Exo and Stone Glacier include belt storage.
- ✗Mystery Ranch publishes no official load rating, so buyers comparing against Stone Glacier's 150 lb spec are left with forum anecdotes.
- ✗The 2025 MYSTERIUM platform is brand new with a thin long-term track record — forum discussion is still mostly first looks and classifieds, and post-YETI-acquisition QC chatter on Rokslide hasn't died down.
