The Alpine Rig

  • 800g weight in average size
  • Simple new harness geometry
  • 30mm Dyneema-blend webbing
  • CAD-to-Laser design & construction
  • CNC cut carbon fiber stiffeners
  • Custom plate buckles


The CXUL is designed for jumping in the mountains. It is ideal for slider up applications where weight and pack volume are a primary concern.

Harness Geometry

The CXUL's new harness geometry is clean, simple, and strong. A double thickness MLW carries full strength from risers to leg loops, with a sleek bridge/lateral junction. The riser/diagonal junction is no-peel, and low-profile.


Proprietary 30mm Dyneema-blend webbing is used from risers to leg loops. The Diagonal is made from Amsteel. The container is made from a blend of poly & sail cloth, with CNC cut carbon fiber stiffeners.

Application & Weight

The CXUL is designed to be used with the IBEX.UL canopy. Total system weight will be approximately 3.9 kg (~8.5 lbs) for an average size jumper. It is designed for slider up Alpine missions.

The CXUL is 100% CAD designed and precision built with laser & CNC cut parts in Squirrel's own production facility. Each rig is hand-inspected by Martin Tilley, of Asylum Designs.

CAD to Laser & CNC

The CXUL was modeled in the same powerful CAD software we use for wingsuit design. Panels are laser-cut, and all load-bearing junctions use CAD-designed stitch patterns placed with automated CNC-bartackers.

CNC-Cut Carbon Components

For reduced weight and increased durability, we chose CNC-cut carbon fiber plates for flap stiffener sections.

Sleek & Simple Geometry

With new geometry throughout, the MLW/Riser and Lateral/Bridge junctions employ a simple, strong, and low-profile design. Amsteel is used for the diagonal and lateral spans.

Light Custom Plate Buckles

Based on our 43mm buckles, and made from the same high-strength aluminum, the 30mm buckles are removable yet secure. If you choose to keep the buckles always attached, then the leg straps function the same as traditional BASE buckles at a fraction of the weight.

Cushioned Leg Straps

Ultralight closed-cell foam backed with a layer of Dacron provides a comfortable amount of cushion with single-width webbing.

New 30mm Dyneema Blend Webbing

Like the standard 43mm webbing used for the CRUX & STREAM series, our new 30mm webbing is custom woven to our spec using DSM yarn. A Poly backing provides a resilient structure for the Dyneema to lay on.
