CRUX VIDEOS
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.
SMART HARNESS
The CRUX harness geometry offers an integrated riser design with a smooth and low profile MLW / Diagonal junction for a low-profile and comfortable fit at the shoulder area, and >22kN resistance at any conceivable angle during deployment.
SMART CONSTRUCTION
Higher strength, more consistent, and more precise: CAD designed bartack patterns are chosen specifically for each segment of the harness, in accordance with the applicable force and direction.
INTEGRATED RAPPEL LOOPS
Rappel loops are integrated into the harness at the hip area. Use your own slings or add the SQRL designed rap slings to your order.
DYNAMIC CORNERS / BOC
We've redesigned the dynamic corners for a more thorough closure. The CRUX opens into a perfectly flat tray once the pins are released and the bottom corners close easily. The length of the container is medium-long, for easy BOC access and comfort during wingsuit & tracking use.
LOW PIN-LOCK TENDENCY
The side flap orientation and pin cover flap design of the CRUX prevent known issues with opposite-oriented container closures. The pin flap gives solid relative wind protection while still allowing pin release during head-high deployments or other acute bridle angle scenarios.
CUSTOM PLATE BUCKLES
Lightweight custom aluminum frame buckles can be attached or released without passing your leg through the loop, or simply left connected forever -- your choice.
CHEST STRAP BUCKLES
The new 30mm chest strap hardware cinches, adjusts, and releases smoothly.

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.
"I’ve been jumping the crux now for 7 years and it is by far my favorite all around container for every type of jumping. Now with the CRUX 2, everything I loved from the original crux such as the fit, weight to durability ratio, and design features are even better.
I have better pin and bridle protection along with a bigger chest strap buckle for when the hands are cold or you’re jumping with gloves. I love this container and keep ordering them! "
" The CRUX 2 isn’t a choice for me — it’s a necessity. From heli wingsuit jumps to committed urban doubles, this container just works no matter where or how I’m jumping. The releasable leg straps are one of my favorite features ever. Gearing up is faster, cleaner, and being able to take the rig off instantly is huge — whether you’re running from security, driving a car, or just trying to keep things smooth. The size of the leg straps, especially with the ability to add SADL sacs, is a complete game-changer. It’s a big reason the CRUX 2 is my go-to container 24/7 — I can bring everything I need, and sometimes I need a lot of shit. The new chest strap is money. Perfect size, great grab feel, easy to clip a radio, and even solid for the occasional XRW in BASE gear. Durability? Ridiculous. I pack on concrete, rooftops, jungle floor, rocks — zero princess treatment — and after hundreds of jumps, it still looks brand new. The structural integrity is insane; it holds its shape and never feels sloppy or worn. If I’m jumping, it’s on a CRUX 2. Simple as that."
"The Squirrel CRUX2 is the container I trust with my life. Built for all-around BASE jumping, it delivers what matters most: simplicity, reliability, and proven performance.
Purpose-built and free of gimmicks, the CRUX2 performs seamlessly across terminal and subterminal jumps. Every detail is intentional, resulting in a system that is predictable, consistent, and confidence-inspiring when the margin for error is zero.
One tool. One job. Done right."
"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."
"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."
"I found the Crux to be an incredible container! The simple and effective operation makes both slider up and slider down applications seamless."
