Stone Glacier Sky 5900
Stone Glacier's do-it-all western pack: a 5,900 ci (96 L with Sky Lid) bag on the curved carbon-stay Xcurve frame, rated past 150 lbs yet 5.5 lbs complete. 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.
Specifications
Features
Pros
- ✓The 150+ lb load rating is real-world verified — GearJunkie packed 110+ lb elk loads and said it 'carries like a dream with heavy weight', a claim Rokslide owners routinely back up.
- ✓Bivy-mode compression is the party trick forum users cite most: the 5,900 ci bag cinches to 4,300 ci with 'zero wiggle', so it genuinely replaces a day pack.
- ✓The fold-out load shelf adds 2,500+ ci between bag and frame (8,000 ci total), keeping bloody quarters off your camp gear entirely.
- ✓Full front-panel horseshoe zipper gives duffel-style access to the main bag — a major livability win over roll-top-only rivals like the Kifaru 357 Mag.
- ✓The 22-inch vertical front pocket swallows a full-size spotting scope, and glassing-heavy hunters call it the best stock optics solution in the category.
- ✓At 5.5 lbs complete (2 lb 4 oz bag), it undercuts most 150 lb-class haulers — the usual Rokslide summary is 'lighter than the competition but extremely tough'.
- ✓Scheels buyers rate it 4.9 stars across 252 reviews with zero one-star ratings, and Stone Glacier's fast shipping and lifetime warranty draw consistent praise.
- ✓Hook-and-loop harness micro-adjustment lets you fine-tune torso length continuously instead of in fixed half-inch steps.
Cons
- ✗Hipbelt pockets cost extra, and Rokslide users say Stone Glacier's accessory hip pockets run small and 'fight back' when zipping them mildly full.
- ✗Organization is deliberately minimalist — one big cavity plus a few externals — so hunters coming from pocket-rich Mystery Ranch designs face a packing-cube learning curve.
- ✗The Sky Lid is the most common gripe in reviews: floppy when open and fiddly to reattach, with GearJunkie calling it the only thing they 'don't really love'.
- ✗$725 before add-ons (lid pockets, hip pockets, rifle sling) — real-world builds push $800, roughly $200 over a complete Metcalf 75.
- ✗The 5,400 ci main bag is 'just barely big enough' for cold-weather multi-day hunts; Rokslide steers week-plus trips to the Sky Guide 7900.
- ✗The Xcurve's pronounced curve fits torsos 20 in and up with rounded backs — flat-backed or shorter hunters must switch to the Krux, making remote fit selection a gamble.
- ✗Stone Glacier's rifle-carry solution trails Kifaru's Gun Bearer in reviewer preference, so many owners bolt on third-party weapon carry.
- ✗Dropping the bag to deploy the load shelf means unbuckling and re-tensioning straps — slower meat-mode transitions than Exo's flap-style shelf.
