Petzl Aquila Review

The Aquila has a very narrow waist belt, but surprisingly this didn't seem to detract from the comfort we found while hanging and belaying with it. What did detract from this harness was the location of the gear loops and ice clipper slots, but even more so, the slipperiness of the auto-locking buckles. Petzl's small aluminum "DoubleBack HD" buckles are found on both legs, as well as the on the waist, and compared to all of the other buckles you can find in this review, come loose by far the easiest.

While they use a similar design to most other auto-locking buckles, it seems like the two pieces are not sewn together optimally, or the top portion is just a hair too small, as these buckles end up relying on webbing-to-webbing friction to hold their tension. While this is still a safe means of keeping a harness closed, it also means that even the slightest change in the orientation of the buckle relieves this friction, allowing the webbing to loosen up all by itself. We found this to be more of an issue on the leg buckles than the waist, and it was only a real concern if the tail ends of webbing weren't long enough to be held under the elastic keepers. Again, compared to the competition, these buckles were problematic, and the correspondingly low score for features kept this harness from being one of the better ones.

Performance Comparison

The Aquila is a nice light and comfortable harness for sport climbing, as Hiroki shows here on the classic Five Gallon Buckets at Smith Rock.

Hanging Comfort

The waist and leg loops of the Aquila are constructed using Petzl's FUSEFORM technology, which they claim minimizes pressure points and effectively distributes a climber's weight. While conducting our hanging comfort tests, it was obvious to us that this method of construction does work as advertised. While there was some pressure underneath our legs across the hamstrings while we hung, this was no worse than we experienced with any other harness. We also noticed that the waist belt seemed to fit snugger, and stayed in place better than the waist of the Petzl Corax, which rode up a bit into our kidneys. We thought this harness was equally as comfortable for hanging in as the Petzl Sama, although not quite as comfortable as the Black Diamond Solution.

The triangle of fabric shown in this photo does a good job of keeping the leg loops in place as they wrap around the front of the leg. Despite its relatively thin design, the Petzl Aquila was indeed a comfy harness to hang in.

Standing Comfort and Mobility

While merely standing around, the Aquila is comfortable, snug around the waist and hips, with no pinches or rub spots anywhere. However, when we loaded it up with a full rack of cams and other gear, we experienced some pressure on our hips and especially noticed the tendency for it to sag in the back away from the body. It has a decent amount of foam incorporated into the waist belt, so wearing a pack wasn't super ideal, but also not uncomfortable.

Due to its adjustable leg loops and minimalist design, the Aquila is very mobile and super comfortable for hanging out in during the day.

When it came to mobility, we found it to be more mobile than either the Sama or the Black Diamond Chaos, both of which have fixed leg loops. There is no doubt this is a comfortable harness for walking in. However, the issue with the loose leg buckles also affects the mobility, especially when wearing lots of clothing on the legs. Despite having adjustable buckles on the leg loops, we found these would automatically loosen themselves unless the tail end of the webbing was kept secure in its elastic keeper strap. This had the effect of lessening the range that we could adjust the legs, as we had to keep them tight enough to have a long tail. While it is mobile enough to be considered for alpine climbing, we would honestly recommend the higher performing Petzl Sitta for this purpose first.

Features

This harness receives a low overall score for features, based largely on the performance of the buckles that we have already discussed, but also because of gear loop issues. First, let's talk about what we like. We love the heavily reinforced, slippery Dyneema coated belay loop and tie in points that minimizes wear over time. We also like that the ice clipper slots are very low profile (although we don't like that they rest under the front gear loops, making for an awkward sit when ice clippers are in place). Adding a strip of grippiness to the inside of all the elastic keeper loops was a nice touch, and we like how easy to clip the rigid front gear loops are.

All three buckles found on the Aquila, but especially the adjustable leg buckles shown here, had a propensity for loosening themselves. On the right you can see that simply shifting the angle of the buckle slightly releases the friction on the webbing. The only way we found to prevent this from happening at random times was if the tail stayed in its keeper, shown on the right, but this minimizes the potential range of adjustment.

On the flip side, we have severe issues with the adjustable buckles, as described above. Beyond that, we felt like the rear gear loops are too small, much like the BD Chaos, and they also live way too far back on the harness, so far back in fact that they are impossible to see, so only non-crucial gear can go back there while leading. Also, we feel like unless this harness fits you perfectly, the gear loops will not end up centered, which forced us to tighten up the waist belt more than we might have liked. Simply put, virtually every feature felt like it could be improved upon, a stark contrast to the other excellent Petzl harnesses such as the Adjama or Sama.

This photo shows the small rear gear loops, as well as the small unrated haul loop on the back of the Aquila. Also plainly visible are the elastic Risers that adjust the height that the leg loops sit against the back of your legs.

Belaying Comfort

When it comes to comfort while belaying, the critical part of the harness is where the leg loops wrap around the inside of the leg and rise to join the belay loop, as this is where the force of holding a climber is concentrated. The Aquila is relatively comfortable for this purpose, roughly in line with the BD Chaos, and simply seems to fit well in this area of the body. It doesn't quite live up to the standard set by the most comfortable harness for sport climbing, the Black Diamond Solution, but it's pretty good.

Holding someone taught while belaying centralizes the forces on the inside of the leg. The Aquila was one of the most comfortable harnesses for belaying in, shown here high in the Wooden Ship gully at Smith Rock.

Versatility

The Aquila is designed to be highly versatile, as it is a modified version of the Petzl Hirundos harness with accommodations made for carrying ice screws and wearing extra warm clothes. The fact is, the Aquila can be used well for any purpose other than trad climbing, making it one of the more versatile harnesses in this review. However, its poorly performing features mean that it wouldn't be our top choice for any style of climbing, especially compared to the ultra-versatile Sitta, which costs more but is a far better harness in our opinion.

The Aquila has the features to make it a useful harness for sport and gym climbing, as well as ice and alpine climbing. However, as you can see here, the rear gear loops are small and so far back as to be completely hidden from the climber. We don't think its the best choice for multi-pitch rock climbs for this reason.

Best Applications

With its versatile feature set, the Aquila can be used for most styles of climbing, with trad being the one style that we would avoid due to not having enough usable racking space. It is probably most suited for alpine mixed climbing and mountaineering, provided your warm clothes don't force you to loosen the leg loops up too much. It also makes for a pretty nice sport climbing harness, and it would work well in the gym as well.

The Aquila is pretty versatile, but since it has such small gear loops, we think that sport and gym climbing might be its optimal style of climbing. Here Hiroki ties in at Smith Rock.

Value

This harness retails for $130, making it one of the most expensive harnesses in the review. We can only assume that the price is due to advanced technology used in the FUSEFORM construction, otherwise, we don't understand how this harness could cost so much more than the Sama. As a harness with some poor design flaws, we don't think this presents a good value, especially at the high price point.

Conclusion

The Petzl Aquila is a highly versatile harness that is also super adjustable, light weight, and comfortable. Unfortunately, it has the poorest feature design of any in our review, and for this reason alone we wouldn't recommend it for most climbers. It is also far more expensive than it seems like it should be — another knock. The fact of the matter is that compared to the competition, the Aquila's flaws became very evident.

Hiroki loving life as he hangs out on a cool day in the fall at Smith Rock, OR. He loved climbing (and belaying) all day in the Aquila, saying he might consider buying it as his next harness.
