This is our first look at the harness and our quick thoughts about it. We will do a follow up detailed review.
If you've seen our review of the previous LIGHTNESS 3, you'll understand why I'm so excited about this new release. The LIGHTNESS 3 was much loved by many pilots and had been around for quite a few years, holding up really well. Now, with the LIGHTNESS 4, Advance has introduced some significant upgrades while maintaining the core concept.
Although the basic design hasn't drastically changed from the LIGHTNESS 2 to the LIGHTNESS 3 and now to the LIGHTNESS 4, there are several fundamental updates to the harness geometry. For instance, the back of the harness looks quite different. Anyone familiar with the LIGHTNESS 3 will notice that the comfort foam is now on the outside instead of the inside. It still features the double sandwich protector, with a stiffer part on top and a softer part on the bottom, giving it more of a seat plate feel and better control.
Another key difference is the increased storage space in the LIGHTNESS 4. The back pocket is now 35% larger in volume, which makes a noticeable difference. There's also a new cockpit design that comes with a removable panel for your instruments, which is a nice touch. The adjustments on the pod are different, and it includes the Edelrid Alias 2 speed carabiners, the same ones found on the Impress 4. While the reserve system is similar, there are some notable changes in its design, which we’ll dive into later.
One of the most visible updates is the addition of a rear fairing for improved aerodynamics, fed by two air intakes on either side. This fairing is similar to the one on the Weighless harness. Additionally, the LIGHTNESS 4 offers more storage options, including a pocket in the footplate and two side pockets—one with elastic for easy access and the other more secure.
The speedbag is now removable and interchangeable, and as always with Advance, the reserve system is simple and effective. During my testing, it performed exceptionally well indoors on the hanging system, with a smooth and reliable zip system extending up to the shoulder attachment points.
In terms of comfort and handling, the LIGHTNESS 4 may set a new benchmark. It’s incredibly comfortable, which is likely due to the new shaping that’s taken the already impressive comfort of the LIGHTNESS 3 to another level. The center of gravity has shifted slightly forward, offering a greater sense of authority and control. There's also a feeling of more support, almost like a seat plate harness.
Comparing it to the LIGHTNESS 3, the new version feels noticeably more stable, yet retains the agility and responsiveness pilots loved in the LIGHTNESS 3. In contrast, the LIGHTNESS 2, which I also enjoyed, was a bit more unstable, similar to the Impress 3. The move from the Impress 3 to the LIGHTNESS 3 was a significant evolution, and now, with the Impress 4 being a much heavier harness with a full seat board, the LIGHTNESS 4 seems to carry forward the best of its predecessors with some innovative tweaks.
Overall, while the concept remains the same, the LIGHTNESS 4 introduces substantial improvements that enhance the flying experience.
Time to go and fly!
