Expedition Rigidity. Without the Weight.
We took three decades of expedition feedback and stripped away the compromises. The Apex Hauler is built around an advanced carbon fiber chassis paired with high-density nitrogen foam — a frame that stays rigid under heavy loads without the weight penalty of traditional aluminum stays.
The result is a high-tech foundation that carries weight close and stable, so the pack works with you on the climb out — not against you.
Engineered to Haul
Every element built to move heavy loads over hard country.
Carbon Fiber Chassis
An advanced carbon core delivers unmatched rigidity under load — without the weight penalty of aluminum stays.
Laser-Cut MOLLE Grid
A streamlined, snag-free MOLLE grid lets you build a fully modular load-out for any hunt.
Nitrogen Foam Backing
High-density nitrogen foam cushions the frame against your back for stable, all-day carry.
Loop Lock System
The innovative Loop Lock system cinches down and locks any payload — from a loaded meat shelf to a spike camp.
Not Just Another Pack Frame
See how the Carbon Core compares to a standard pack frame.
Rigid under heavy loads at a fraction of the weight.
Add rigidity but pay for it in pack weight.
Locks down any payload, large or small.
Straps shift and loosen under an uneven load.
Streamlined, snag-free modular attachment.
Bulkier, heavier, and less configurable.
Drops onto our legacy Duplex pack bags.
Frame and bag are one — no mixing setups.
Frequently Asked Questions
What is the frame made of?+
An advanced carbon fiber chassis paired with high-density nitrogen foam — rigid under load, without the weight of aluminum stays.
Which profile should I choose — 22″ or 25″?+
The 22″ profile suits shorter torsos and lighter, faster setups; the 25″ profile gives taller frames and heavy haul-outs more load support. Measure your torso and size to fit.
Is it compatible with my existing Duplex pack?+
Yes — the Carbon Core is fully compatible with our legacy Duplex pack bags, so you can run your current setup on the new frame.
How does the Loop Lock system work?+
Loop Lock lets you cinch and lock a payload directly to the frame — from a loaded meat shelf to bulky camp gear — so nothing shifts on the pack out.
Carry Heavy. Move Light.
The Apex Hauler pairs a carbon fiber chassis, nitrogen foam, and the Loop Lock system into one high-tech hauling platform — built for your most grueling hunts.
