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.



  • Review

    "My CXUL is 200g lighter than the special light CRUX you made me, which already felt light. The plate buckles feel great and after having them on my other rigs, I can't imagine a container without them, especially when gearing up on a sketchy exit point. Nothing like throwing your rig and wingsuit on like a backpack without having to hop around to get through all the straps. I was concerned with comfort with the thinner leg straps but happily put those worries aside after my first few jumps, this thing is comfy! Really thin, really light, looks nice when packed (even a bit sloppy), and BOC in the perfect spot. What else can you ask for?"
