This versatile and low profile container system is designed for all types of BASE jumping, from low freefall to wingsuit and everything in between. The CRUX is an ideal choice for jumpers who want an all-in-one solution. All CRUX options are included in the price.

If you’re looking for a 3-ring system, go to the CRUX 3R.

Pin Protection

Integrated riser cover / side flaps prevent flap-edge exposure. The CRUX’s pin cover flap is designed with versatility across all BASE applications in mind. It is smooth and aerodynamic for wingsuit and tracking use while also being slider-down friendly.

Low Pin-lock Tendency

Like the STREAM and kN, we began development of this harness with awareness and knowledge of known issues in older harness/container designs. The pin flap protects your bridle from airflow while still allowing immediate release during a head-high or otherwise unstable deployment. We think you will agree that the balance between coverage and forgiveness in situations of acute bridle angles is excellent.

Smart Harness

The CRUX harness geometry offers an integrated riser design with a smooth and low profile MLW / Diagonal junction. This allows a low-profile and comfortable fit at the shoulder area, and >22kN resistance at any conceivable angle during deployment. The “bridge” reinforcement joining the rear diagonal / MLW / riser junction prevents peeling load and is a clean and simple solution to the known issues that affect previous integrated riser designs.

Smart Construction

Traditional construction techniques work, but some modern construction techniques work better. By better, we mean stronger and more precise. Programmed bartacks offer a high level of precision and consistency from harness to harness. The CAD designed bartack patterns are chosen specifically for each segment of the harness, in accordance with the applicable force and direction.

Custom Plate Buckles

The leg straps are secured with aluminum frame buckles, which can be attached and released without passing your leg through the loop. This is a useful option for gearing up on precarious exit points, or while on rappel. If you prefer to pass your legs through closed loops, this is also possible – just leave the buckles mated together.

Dynamic Corners / BOC

The CRUX opens into a perfectly flat tray once the pins are released, but the bottom corners close easily and fully secure your packjob. The overall length of the container places the BOC in between the kN and STREAM, making access more comfortable for wingsuit and tracking but not so low as to require cut-in laterals.

Tapered Laterals

This tapered cover allows a slightly longer container design, without the creation of an exposed corner, making the CRUX a bit friendlier for BASE aerials.

Dyneema Webbing

Our blended Dyneema webbing is a traditional width (similar to type-8) but is significantly stronger and lighter than type-8. It is tested to a 7000lb (31kN) breaking strength. The white face is Dyneema, woven together with Polyester (black) for structure and durability.

NBS System

The NBS (No BS) system is an important development in modern harness design. If you would like to learn more about the different types of harness geometry that are being advertised today, then please contact us for a complete history on cross-bracing (from its arrival on the paragliding scene in the 1990s to present), and a detailed education on the true causes of, and real cures for, line twists and body twists, both in BASE and Wingsuit BASE. We will be happy to discuss harnesses and technique in great depth with you.

    "With the Crux, your hand just follow an easy path to the PC even in a large wingsuit. The Crux/Hayduke/Snatch Team is not only awesome for wingsuit activity, it's a blast for regular and technical slider up and slider down jumps. I have consistent nice on heading openings. The Hayduke is very efficient for low jumps and technical tight landing areas. That's a very cool & versatile equipment built for fun!

    "For me it is important that a container fits well and is comfortable at the exit and under canopy. The Crux meets those needs perfectly. The top of the container hugs to top of my back nicely and the riser/riser covers run smoothly over my shoulders. It is of lighter construction but still has some stiffness in the sidewalls and bottom corners to make it easy to pack and give it some shape. I found it easy to pack/close without having to change anything in my regular packjob. I tried bottom first, top first, floor plate and top flap – all very easy. A very good looking, very comfortable and excellent fitting container that is a breeze to pack.

    My experience with the Crux/Hayduke was great. For my jumping style (SD in Moab) the Crux/Hayduke is a great fit. The Crux/Hayduke would be my go-to rig in Moab. I assumed I got a ‘loaded’ demo package, but see that all the things I assumed were options (Dyneema Blend webbing, releasable leg strap buckles and padded back pad) are actually included, which makes this an even more attractive and well-priced package."

    "The rig is truly amazing. The simple functionality of the Crux Container and the predictable flight characteristics of the Outlaw Lite 260 really elevated my experience the past three weeks in the desert.

    I love my _ _ _ and my ___ canopies, however the Outlaw Lite 260 is by far my canopy of choice after this past trip. I would consider myself an average canopy pilot, not an expert by any stretch of the imagination. I was able to predict the flight characteristics and capabilities of the Outlaw and nail every landing target, flare, and talus flight line. The Outlaw is my canopy of choice from now on.

    The way the two components fit together is perfect. I would change nothing. The large tail pocket with the velcro on the outside, the riser covers that lay in and fold over so perfectly, the velcro stowage for excess brake line..... basically the whole package is amazing."

    "It’s simple, light weight, and comfortable. I really like that you can choose to use the floor plate or the top flap for closing. It’s comfortable on the exit point as well as under canopy."

    "Finally got my Crux from Squirrel. Hands down the nicest base container I've ever had and my personal favorite piece of kit right now.....period. I'm serious, after my wife and my dog this is the next thing I would grab from a burning building. Not joking. My favorite things about the Crux are:

    The insanely light legstrap hardware and ability to use them either in the conventional pull-to-tighten method or paraglider style quick detach. Omnidirectional harness stitching. An intelligently thought out and actually useful (for once) hook knife pocket. Comfortable, lightweight legstrap and back pad foam. And of course, a Squirrel nut with wings :)

    Thank you to Squirrel for continuing to make badass gear for the masses and for having our backs.... literally."
