The Arc'teryx Kyanite stands out as a favorite to wear around town and on the trail. The lightweight and stretchable Polartec fabrics offer exceptional warmth and movement that vents when needed. It's not the most breathable fleece out there but does the trick for less sweaty excursions like a Sunday afternoon hike or climbing session at the cliff. It's simple and stylish and offers a slim and stretchy fit. While we appreciate many features of this jacket that can either worn alone or as a mid-layer, we are less than thrilled about the zipper that doesn't stay put and slides down. The price is also quite high. While it can be used as a technical fleece, this is a perfect warm friend on a fall hike or as a warm mid-layer when the temperatures begin to plummet.

Our Analysis and Test Results
The Arc'teryx Kyanite can easily transition from work to the trails. This versatile and sleekly styled lightweight fleece is a perfect choice for fall hikes and chores around the house, and it offers many features that provide a gauntlet of uses. We just wish the alleged "non-slip" zipper would stay in place, and it wasn't so expensive.
This wonderful lightweight fleece packs a lot of warmth into its thinner layers. The outer Polartec shell provides some wind protection, while the interior, soft fleece works to keep the body warm and protected from cold weather. The fleece insulates both when wet and dry, offering lots of warmth in any condition. Wear it on its own or as a jacket on cool days.
From hot summer days to cold fall nights, we wore this jacket in a plethora of conditions. We used it as a wear-alone piece and wore it underneath other jackets on cold days. What we learned is that for lightweight fleece, it's pretty darn warm. It offers decent thermoregulation but holds its heat; as a result, we'd recommend it as a mid-layer during cold days in the winter or as a stand-alone jacket in the winter and fall.
The interior fleece is ridiculously soft and feels so good on the skin. When we first put it on, we didn't want to take it off! The Polartec fabric stretches in all directions and offers a good amount of room through the shoulders, torso, and hips.
The wrists are simple, without any loops or hems in the material. This jacket has two handwarmer pockets (not fleece lined) and an interior chest pocket that's large enough to fit a smaller iPhone. The hood is helmet-compatible and fleece-lined, providing the ultimate in comfort.
Our only caveat in this category is the zipper. In addition to many online users that have reported the "no-slip zipper" sliding down on its own, we noted this problem as well. When it is zipped up about ¾ of the way, and we move, the zipper travels down.
This annoying feature lost many comfort points here. That said, when it's completely zipped up, we had no issues. We strongly urge Arc'teryx to fix this issue, as keeping a jacket zipped shouldn't be as big an issue for such an expensive product. Aside from that, we love this layer, and it's our preference for wearing on most days.
The Kyanite provides good thermoregulation, but it's not the best out there. The exterior face fabric is continuous, while the interior architecture is made up of continuous fleece along the back for moisture-wicking and insulation. The front of the fleece features a more breathable mesh that attaches and accommodates the pockets built into the jacket.
We wore this jacket while hiking, running, and playing around town. In all cases, we noticed that it provides good breathability, especially in cold weather. But we found ourselves taking it off when we began to sweat. In general, it has an above-average level of thermoregulation but ultimately keeps you warmer than cooler. As a result, we'd recommend it for activities that aren't super sweaty, like day hiking and wearing around town. It's not our first choice for highly aerobic activities like ski touring or running.
This fleece can layer well but can get stuck on thicker baselayers. Designed to be worn on its own or in a layered system, the Polartec Stretch Pro fabric provides a considerable amount of stretch.
It stretches well but doesn't offer as much room as others in the review. The arms around the shoulders are a little tighter, and if you're wearing a midweight or heavyweight baselayer (depending on the material), it can bunch and gra; this is a result of the fleece-lined interior. With thinner baselayers or t-shirts, we had no trouble. The face fabric is continuous and doesn't have much friction, so it layers effortlessly underneath other jackets or larger fleeces.
Ease of Movement
The stretch provides easy movement for all sorts of activities. The arms are long enough to accommodate long limbs, and the jacket doesn't ride up when you reach up. We do wish it was a tad bit longer in the torso. The wrists don't have any thumb loops, so you don't have the option to keep the arms pulled down when reaching up, but it doesn't move much anyway, so we're not too worried about that. We love that the fleece stays where it should, without needing too many adjustments.
Weather resistance is about the same as most fleeces in this review, offering an average level of protection. We took the Kyanite with us to Red Rocks, Nevada, where the winds can be pretty strong; we stood up high to see how the continuous face fabric holds up to super gusty conditions. When worn with a base layer, we didn't notice the wind ripping through the fabric. But, without, we are sure the results wouldn't be as positive. As a result, we'd wear it in windy weather with a light windbreaker or thin base layer underneath.
For wet weather, it provides some basic resistance but is far from waterproof. In our water tests, we poured a little water on the face fabric. For a moment, when there were just a few beads, it did a good job of repelling the droplets; the water didn't absorb at first and simply dribbled away.
We also observed the same result when wearing it during a light rain shower. However, when more water was added, and the rainstorms got heavier, the fabric readily absorbed the water. During our objective water tests, it provided resistance from complete absorption for about two seconds, before the 100mL of water absorbed into the fabric. Even though the water absorbed into the fabric, it didn't transfer into the inner layers, which means more protection during wet storms.
As a result of these tests, we'd recommend this fleece for wearing under a light rain jacket or windbreaker when the weather gets bad. It'll do fine for some wind, but doesn't offer the same protection as an insulated jacket or softshell; just as you'd expect.
This jacket is quite expensive. Some people might be willing to shell out the extra dollars simply because it is quite stylish and versatile. However, for those looking to pinch pennies, there are better options with better value. That said, the materials used are durable, and the fleece hasn't shown signs of pilling or durability issues after wearing consistently for a few months. If you're seeking something similar, but less expensive, take a look at the jacket, retailing for a little less.
The Arcteryx Kyanite stands out as a lightweight and fashionable fleece that offers technical performance. It's perfect for wearing as a mid-layer in the winter while milling around town, or as a light hiking jacket in the Fall or Spring. It is expensive, so be sure you're ready to throw down if you fall in love with it.
