Eberlestock Modframe

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.

Revamp 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 

Pack Design & Load Management:

• 3626 cubic inches of storage for light multi-day trips
• Roll-top closure for adjustable capacity
• Front zippered access to the main compartment for quick gear retrieval
• Interior pockets keep essentials organized and easy to find
• Side, front, and bottom compression straps secure loads tightly to the frame
• Long side zippered pocket and two front stretch pockets for quick-grab items

The Brooks 3500 is tough enough for alpine hunts, bushwhacking through thick timber, and unpredictable weather. 500D ripstop and rugged hardware ensure reliability trip after trip, and at just 1 lb 15 oz, the Brooks 3500 offers exceptional capacity without weighing you down.

Compatible with the full range of Hunt EMOD™ accessories, the Brooks 3500 adapts to any hunt. Add an EMOD™ Lid, Bolt-Action Scabbard, or Batwings to expand carrying capacity, or strip it down for greater mobility.
