Pros & cons
Kuiu ICON 6 6000
- ✓At 6 lb 2.4 oz for the complete 98 L kit, it undercuts comparable Kifaru and Mystery Ranch expedition haulers by a pound or more while keeping a genuine load-hauling frame.
- ✓The 3D corrugated thermoplastic carbon frame is engineered to yield rather than shatter — a direct answer to the cracked carbon frames Rokslide users reported on the old Pro system.
- ✓Load-sling mode opens roughly 5,000 cubic inches between bag and frame for quarters, and the Pack Load Hauler doubles as a glassing pad for direct on-frame meat hauls.
- ✓$699 buys the entire kit — frame, bag, two hip belts, load sling, rifle quick release and gear strap — while Rokslide posters note comparable Exo K4 and Stone Glacier builds push north of $800.
- ✓The horseshoe zipper across the back panel lets a rifle or a whole elk quarter slide down against the frame without unloading the bag, a feature early reviewers single out.
- ✓An internal waterproof-coated drop pocket carries up to 45 lbs of boned-out meat high and tight against the frame, keeping the weight where the suspension can handle it.
- ✓Hook & Barrel's tester found the suspension 'began to distinguish itself around the 80-pound mark' with zero frame creak or squeak — a common gripe on older Kuiu carbon frames.
- ✓Nearly five inches of half-inch-increment shoulder adjustment plus Regular and Tall frame heights covers hunters from 5'2" to 6'6", with a dedicated women's version.
- ✗Zero backward compatibility — Kuiu states the ICON 6 'shares zero key components' with the Pro/Pro LT systems, so existing Kuiu bag owners must rebuy everything, a sore point on Rokslide.
- ✗Kuiu pack skepticism runs deep on Rokslide — veteran posters still say the frames aren't at Stone Glacier or Kifaru level for comfort under loose meat and heavy quarters.
- ✗It's a brand-new 2025 system with essentially no multi-season durability record, versus the proven Exo K4 and Stone Glacier Xcurve platforms it competes with.
- ✗Kuiu's 'Regular' frame sizing historically runs short — forum users warn hunters around 5'9" and up end up with weight stuck on their shoulders unless they size up to Tall.
- ✗Tall frame variants were sold out in every suspension size at the time of research, so long-torso hunters may face a wait.
- ✗Only 7 verified reviews existed on Kuiu's site as of mid-2026, so crowd-sourced validation is thin compared to packs with hundreds of reviews.
- ✗No rain cover is included; the uncoated weight-saving panels and unsealed seams mean a soaked pack in sustained downpours without a liner.
- ✗At $699 the kit costs $100 more than the outgoing Pro 6000, and it's over twice the weight of ultralight crossover haulers like Seek Outside's Divide if you don't need the full 98 L.
Stone Glacier Col 4800
- ✓Fills the gap Rokslide members begged for between the Solo 3600 and Sky 5900 — owners of both call roughly 5,000 ci the sweet spot for everything from day hunts to 5-day backcountry trips, and several say they'd have skipped the 5900 had the Col existed.
- ✓Solves the Solo's single biggest complaint: dual front pockets plus an external side stuff pocket give real organization, and Solo upgraders on Rokslide specifically praise having a dedicated spot for a bugle tube or Nalgene instead of one overstuffed pocket.
- ✓Internal spotting-scope pocket plus tri-slide attachment points for Swing-Out and Camp Pockets let you build out the interior — a modularity approach closer to Kifaru's without the weight penalty.
- ✓Complete system is only 4 lb 7 oz on the Krux frame yet keeps the full 150+ lb load rating and 2,500+ ci expandable load shelf shared with Stone Glacier's biggest expedition bags.
- ✓Thoughtful weight distribution for carrying a rifle or bow alongside a tripod and spotter — the layout was designed around glassing-heavy Western hunts rather than adapted from a backpacking bag.
- ✓500D Cordura and X-Pac construction with YKK #10 zippers and Duraflex hardware, sewn in Bozeman, MT with a lifetime defect warranty — the same materials story that wins Stone Glacier cross-shopping against Mystery Ranch and Kuiu.
- ✓4.9/5 across owner reviews on stoneglacier.com, and Rokslide field reports from elk hunters rate it more practical than the 3600 for multi-day use.
- ✓Same $699 price whether you choose the lighter Krux frame or the load-focused Xcurve, so you can match the frame to your typical pack weights instead of paying for an upgrade.
- ✗Not compatible with the Sky Series Lid at all — unlike the Sky 5900/6900 there is no lid option, which caps flexible overflow storage on longer trips.
- ✗One detailed Rokslide review returned the pack over limited top-end compression and awkward antler/rack attachment — lashing a rack to the top costs you even more compression, a task the Sky bags handle better.
- ✗The spotting-scope pocket is internal-only with no external zipper access, so unlike the Sky Archer 6400 you have to open the 3/4 main zip to grab your spotter.
- ✗Still no stretch side pockets for a Nalgene or trekking poles — the most repeated Stone Glacier gripe on Rokslide applies here despite the added stuff pocket.
- ✗Hipbelt pockets, hydration sleeve, and interior organizer pockets are all sold separately, so a fully built-out Col runs well past the $699 sticker.
- ✗3/4 zip access falls short of the Sky 5900's full front-panel zip for digging out gear at the bottom of a loaded bag.
- ✗Released in 2023, so it has a fraction of the long-term track record (and only 19 site reviews) compared to the hundreds behind the Sky Talus 6900 and Sky 5900.
- ✗At $699 complete it costs meaningfully more than a Mystery Ranch Metcalf or Exo K4 4800 system on sale, and the frame-plus-bag price advantage only materializes if you later swap bags on the same frame.
