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. 



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.



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.



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.



This doesn’t serve a highly technical purpose, but we think it’s a nice detail. Thermoformed closed-cell foam is laminated in a 4-way stretch coating for comfort and durability. This backpad is not certified or designed to provide spine protection, it serves only an aesthetic and comfort function.



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.



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.



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.



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.



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 Squirrel 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.
