|Pros||Very light, low bulk, easy to manipulate, very small bar tack||Low weight, very thin, handles great, affordable||Relatively easy to untie weighted knots, comes in large selection of widths and lengths, affordable||Stiffness allows for easier placement, high abrasion resistance, high heat resistance||Most affordable, handles great, elastic stretch properties when catching a fall|
|Cons||High price, harder than some to untie knots||Weighted knots harder to untie than thicker slings||Bulky for 11mm, not the best friction for alpine quickdraws, not as smooth as others||Slightly heavier and bulkier than Dyneema slings, stiffness makes it more difficult for alpine draws||Heavy, bulky, lots of friction in alpine quickdraws|
|Bottom Line||A top-notch sling at a top-shelf price||The best climbing sling due to its great handle and low weight and width||Our Top Pick for Building Anchors due to the ease of untying tight knots||A versatile specialty piece that is worth having on the rack for use as protection||The best option for traditional climbers who want to save some money|

Our Analysis and Test Results
The Petzl Pur'Anneau Sling compares very favorably to our Editors' Choice award winning Mammut Contact Sling, weighing in at the exact same 19g, the lightest in the review, despite the fact that it is 2mm thicker. The sling is made of a flat piece of webbing instead of tubular like the Contact Sling, and is very soft and supple in the hands and easy to manipulate. We also love how small the bar tack is compared to the rest of the slings we tested, certainly begging the question, "why can't they all be this small?" The one area where this sling performs a bit lower than others is in our knot test: we find that the soft, flat webbing does a better job cinching down tight into a figure-eight knot than some of the thicker and stiffer slings, such as the Camp USA 11mm Express Dyneema Runner, which unfortunately means that knots are harder to untie after being weighted. Our largest (and only) complaint about this sling is the price, as it is the most costly sling in this review.
This sling is made out of what Petzl calls "high-modulus polyethylene," which is essentially the same compound as Dyneema, but without a stated brand name. It is extremely smooth and supple to the touch, without any hint of stiffness. Like all Dyneema slings, it has a small amount of Nylon fibers on the edges, although as far as we can tell nowhere near the same amount as the Metolius Open Loop Sling, which is also stiffer. We love how the bar tack on this sling is significantly smaller than on all the other slings, and because it has to be rated to the same 22kN strength rating, it makes us wonder why all of the slings can't be sewn with a small bar tack. Despite that, it still has tabs on either end that can hang up on biners occasionally.
Our results in the knot test are pretty much the only knock, with the exception of price, that we have against this sling. We find it easy to tie knots due to its supple nature, although like most slings it is easy to incorporate twists into the knots. However, it is this same flexible suppleness that enables a figure-eight knot to become tighter welded than similar width slings, such as the Black Diamond Dynex Runner or the Sterling Dyneema Sling. After weighting, we find this sling a bit harder to untie than those other two, and so rated it a hair lower. While we tested the 60cm version, it also comes in 120cm and 240cm versions, which would be good lengths for equalizing pieces at an anchor, but this sling will work better for those purposes if you avoid tying figure-eight knots.
Alpine Quickdraw Test
With a skinny 10mm width and thin shape, there is less friction with this sling between itself or a carabiner when making an alpine quickdraw. This allows for easy equalizing of the tripled up loops in short mode, and also allows for very simple and easy extending into long mode. After many tests, one time we did experience the bar tack, with its tabs hanging off the two ends, hanging up on the carabiner as we extended it, but this affront was minor. In general, we think it is one of the best at this task, on par with the Sterling Dyneema Sewn Runner, which has a rubberized plastic sheath covering its bar tack.
Despite the extra two millimeters of width difference between the Pur'Anneau Sling and the Mammut Contact Sling, the two tie for the lowest weight at a mere 19g. This is a hair lighter (probably literally!) than the Trango Low Bulk 11 Sling, which is 11mm wide. It is also a tad lighter than the similarly 10mm wide Black Diamond Dynex Sewn Runner. If weight is a concern for your selection, then the Per'Anneau should be a top choice.
At only 10mm wide and as flat as can be, this sling is easily one of the least bulky that you can buy, ensuring that it racks very nicely on the harness without taking up too much space. It is the same width as the BD Dynex Runner, although that one bulges in the middle and tapers towards the edges, while this one is simply perfectly flat. While bulk may not be the most important metric for choosing a sling, we think there is no reason to not choose a less bulky one if that is available, making this sling a great option.
The Petzl Pur'Anneau Sling is an ideal choice for extending pieces of protection while on lead to reduce rope drag. In particular it is a great choice for long routes or in the alpine where weight and bulk are larger considerations. It comes in 4x and 8x lengths for use equalizing anchors, but if you intend to use it for this purpose, be warned that it can be hard to easily untie welded figure-eight knots.
This sling is far and away the most expensive sling in this review. That still isn't a whole lot of money, and we think that you are getting an excellent product, and a good value. However, almost any other sling in this review will provide adequate performance for less money, so this isn't a very economical choice.
The Petzl Pur'Anneau Sling is one of the highest rated slings in our comparative performance testing, and is particularly noteworthy for its low weight and bulk, as well as its soft, supple handle. It would easily be one of our top recommendations if it wasn't considerably more expensive than any other sling in this review.
