With the Modframe™, we’ve taken everything that made the Mainframe great and rebuilt it from the ground up. This is more than an upgrade; it’s a next-generation hunting platform.

The Modframe™ is a purpose-built foundation for serious alpine hunters who demand performance, durability, and flexibility in their pack systems. Built leaner, stronger, and more customizable than ever before, it offers new levels of fit, comfort, and load control, and it’s fully compatible with every pack, bag, and accessory in the Hunt EMOD™ system.

• Pair with Batwings or a Vapor 2500 pack for lightweight mobility
• Step up to the Brooks 3500, Vapor 5000, or Brooks 7000 packs for extended trips
• Add the EMOD Lid, accessory pouches, or Bolt Action Scabbard to quickly access your essential gear and increase storage capacity

When it’s time to pack out, detach your pack, strap your game bags into the load-panel, and reattach your pack. This keeps the heaviest weight close to your back and reduces fatigue.

Revamped Suspension System:
Modframe ™ features a reimagined shoulder and hip-belt harness with over 50% more padding than our previous design. It wraps the shoulders and lower back in form-fitting comfort, while extra-tall load lifters keep weight off your traps and over your center of gravity, allowing you to go farther without wearing down.

• A new torso adjustment system allows for an exact fit, with unlimited height customization
• Raised load lifters improve balance, helping you fine tune where weight rides
• Our thickest-ever lumbar pad locks in place with silicon grip strips, keeping the pack ideally positioned on your lower back
• A single forward-pull strap on each side makes hip belt adjustment quick and easy, even with one hand
• Rear micro-adjustment straps allow you to fine-tune frame tension for maximum stability
  
• Belt will extend out to 50 inches end to end.

Integrated Load Panel:
At the heart of Modframe™ is a low-profile load panel that replaces the traditional L-frame shelf. This keeps weight closer to your center of gravity, improving posture, energy efficiency, and control during heavy pack-outs.

• Dual integrated 20mm straps quickly secure heavy quarters
• Top and bottom adjustment points let the panel flex out for larger loads
• Compression straps buckle over the panel to pull weight inward and minimize shifting
• A central mesh channel boosts airflow and promotes curing during extended pack-outs 

Supreme Durability:
The Modframe™ is engineered for years of hard use in alpine environments. The frame itself is built from aircraft-grade aluminum and polycarbonate, efficiently blending strength and flexibility. Its interior panel flexes laterally with your stride, allowing the pack to move with you, while the vertical frame structure keeps gear centered and tight to your back.

• Constructed with rugged 1000D and 500D ripstop nylon
• Soft air mesh backing provides breathability and comfort
• Weighs just 4 lbs 8 oz. making it leaner than the Mainframe with more features
• Comes with our Lifetime Warranty
