Mystery Ranch Blackjack 100 Pack – Ultimate 100-Litre Expedition & Sustainment Rucksack

Elevate your load-carriage game with the Blackjack 100 Pack, a 100-litre (≈ 6,100 cu in) high-performance backpack built for the most demanding missions. Designed based on special-operations legacy (the SPEAR/RECCE system) and engineered for durability, modularity, and heavy-load comfort, it’s the go-to choice for multi-day expeditions, tactical sustainment or serious outdoor use. 

Key Features & Benefits

  • Massive 100-litre capacity: With approximately 6,102 cu in of volume, this pack accommodates full kits, multi-day gear, shelters and more.

  • Heavy-load framing system: Utilises the “Military Light Frame” (MLF) with carbon-fibre stays, bolsters and structural extension to stabilise tall loads and ensure load transfer. 

  • Top-loading + side-zip access: Offers a shroud top load plus full-length dual side zippers for rapid access to gear deep in the pack. 

  • Durable, mission-grade fabric & hardware: Constructed from high-end laminate and 500D/700D/500D Cordura® with Dyneema® reinforcement, IR-compliant YKK® zippers and water-resistant finishes. 

  • Modular and mission-ready features: Includes removable lid that can convert to a bolt/E&E pack, pass-through ski/long-item pockets, hydration port for antennae/cables, and PALS/MOLLE webbing for attachments. 

  • Multiple exterior pockets: Four external pockets with top-open zippers plus side pockets for water bottles or gear.

  • Outdoor adventure or remote travel requiring a pack you can trust under real stress

  • Mountaineering, ski-packs, or long treks where side access and gear-pass-through functionality matter
