Our Analysis and Test Results
We tested the Kor Preshell in a variety of environments. From long day hikes in the cool spring months to trail running in the desert, this jacket excels at handling aerobic activity. We also went rock climbing, and while it is not the most durable, we are impressed with its stretch and its hardly-noticeable weight. The Kor Preshell is a niche jacket, best for ultralight pursuits, and we have awarded it our Top Pick for Ultralight Adventures.
Compared to some of the heaviest jackets we tested in this review, the Kor Preshell feels like it is made out of Kleenex! Looks can be deceiving, though, and though it feels light in hand, it is actually made out of Pertex Quantum Air, a ripstop nylon fabric with stretch. This fabric is certainly the least weather-resistant and least durable of the reviewed jackets, especially when faced with our shower test to see how long it can withstand water.
It did not fare well, but let's also be honest that it is not a rain jacket. The Kor is an ultralight jacket that does best at blocking winds, and adding some extra durability to a baselayer you might wear underneath. We favored this jacket on trail runs, mountain bike rides, and climbs that did not have a lot of contact with the wall — and when the skies looked a bit more ominous, we reached for a more weather resistant layer (that weighs a good bit more!)
OK, the Kor Preshell is not the most weather-resistant softshell we have ever tested. But the most breathable? It wins that designation by a landslide and is at the top of the ranking in this metric. The Pertex Quantum Air fabric is so light that it breathes much better than any shell we have ever worn, so much so that we barely even registered that we were wearing it, even while on strenuous mountain hikes. Whether wearing this jacket over a t-shirt or a base layer, we did not notice any extra moisture buildup inside.
We went on high-output trail runs in this layer, and were very impressed with how well it performed. To be fair, part of its exceptional breathability may come from the athletic fit that does not allow for wearing anything too bulky underneath — we usually only wore a thin long sleeve. It also does not have a lot of pockets that allow for any extra heat to get dumped, but we did not find that to be an issue.
The Kor is a trim-fitting jacket that is lightweight and mobile as long as you don't need to fit a bunch of layers underneath it. It is the tightest-fitting jacket in our review, and we say that as a compliment. It is slim so that when you are running, cycling or climbing, you do not have any extra bulk or weight.
The panels on this shell are well cut, and the fabric does have some stretch, allowing for more freedom of movement during aerobic exercise — though at most we could fit a lightweight fleece pullover underneath before starting to feel constricted. The Kor is also cut fairly short, which we only really noticed when wearing it while climbing. It does fit underneath a climbing harness, though reaching high overhead, we could feel the hem pull up more than other models we tested.
We could not believe our eyes when we put the Kor Preshell on the scale to weigh it. Just 4.5 ounces? What?! We have tested some pretty light jackets in past reviews, but this one just blows the rest out of the water. It is not only light, but it's also extremely packable, fitting inside its own inside pocket complete with a clip-in loop for attaching to the back of a harness on a long climb.
The weight of the Kor does come at the cost of durability, though, so recognize that this jacket will not stand up as well to abrasion as heavier-duty options.
When scoring the Kor Preshell on versatility, we considered style, features, and how useful the jacket is in a range of applications. This is a pretty specialized jacket, and it does incredibly well at what it is designed to do, though it did not score high this metric. A lightweight windshell that can also repel some light rain, it is excellent for light-duty use in relatively mild conditions, but it does not have a lot of utility in moderate or severe weather.
We found, however, that in cooler weather sports, we could easily wear a down jacket over the top of the Kor Preshell, gaining warmth as well as wind protection, thanks to the trim fit. It has two small handwarmer pockets that you can stash some gels or a thin pair of training gloves in. There is a hood, though it does not have adjustments, and it does not fit over a climbing helmet.
The Kor Preshell Hoody costs about as much as our Best Buy Award winner, though it is a third of that jacket's weight. It is not super versatile and is one of the lower-scoring jackets in weather resistance, but if you value weight and breathability above all else, then it is a reasonable value.
The Kor Preshell Hoody is crazy light. Light enough that we forgot we were even wearing it. And light enough that if you decide to take it off, you won't notice it in your pack, either. It is a great option for those sports that need the best breathability, but also might need some light weather protection from drizzle and wind. Our favorite jacket for cycling and trail running, this niche piece does not work well for all weather conditions or for all activities, but as an ultralight windshell that is easily tossed into a pack no matter what the weather forecast calls for, we have decided to award it our Top Pick Award for Ultralight Adventures given its prowess in this category.
