Our Analysis and Test Results
The Arc'teryx Kyanite is the cream of the crop when it comes to performance fleece wear. Warm, incredibly comfortable, and built to move, this fleece is ready for any cold-weather adventure you have in mind. The scuba style hood fits comfortably under a helmet, while the stretchy wrist cuffs help keep out cold air. This jacket accommodates wide-set shoulders and doesn't obstruct your range of motion in the slightest.
Performance Comparison
Warmth
This fleece straddles the line between being a light and midweight fleece. Warmer and more wind resistant than micro grid fleeces, this piece makes a decent stand-alone option in moderately cold weather and adds substantial warmth if you're using it as a part of a layering system. If you are looking to build out your cold-weather layering system for wintertime pursuits, this is an ideal choice.
Our testers found this jacket to be a little too warm to wear while on the go for spring ski tours but just right for wearing under a shell while sitting on the lift at the resort. All in all, this jacket has an excellent weight to warmth ratio.
Comfort
What separates this jacket from the pack is how comfortable it is. The brushed fleece liner feels great against bare skin, and the seams didn't rub or feel tight on the shoulders or under the armpits.
The material used throughout is incredibly stretchy and leaves you feeling unencumbered while on the move, even during sustained overhead movements like rock climbing.
The top of the front zipper is lined with a soft fabric, so when you're fully zipped, there is no unpleasant rubbing against your chin. The scuba style hood fits snuggly against your head and doesn't droop down over the eyes.
Breathability
This is one of the most breathable midweight fleeces we reviewed. While it's not as breathable as some of the lightweight microgrid fleece options we tested, it does a good job considering how much warmth it provides.
This wouldn't be our first choice to use as a jacket to go running in, but it is breathable enough to wear while wintertime skiing and hiking.
Layering Ability
With a slim but not skin-tight fit, this piece is the ideal cut to both layer over and under. The wearer has plenty of room to wear a long sleeve base layer, and the slim fit makes putting an insulating layer and a shell over top a non-issue.
Our testers would have liked to see the inclusion of thumb loops in the wrist cuffs to make layering even easier. Having loops to hook your thumbs on keeps your sleeves from getting bunched up underneath other layers and helps keep the sleeve securely tucked into gloves when it's cold and windy out.
Weather Resistance
While the tight weave of the material does a moderately okay job at keeping out the wind, there is no waterproofing to speak of, and you'll need to immediately layer up if you encounter any precipitation.
The jacket is an ideal standalone piece for cold and dry environments and makes a great layer to wear under a shell for when it's wet and cold.
Weight
Our size medium weighed in at 13.97 ounces. While it's not the lightest fleece available, it does have one of the best weight to warmth ratios. It's packable enough for the backcountry or a long hike, but if you're after a fleece that's ultra lightweight, you may want to look elsewhere. If you're after more warmth and wind resistance, the extra weight you'll be carrying will be well worth the trade-off.
Value
Our testers had very few complaints about this jacket and found the comfort to be superb and the details refined. Arc'teryx products are often priced well out of the range of many consumers, but we found this piece to offer a good value. While it's one of the most expensive fleeces we reviewed, it wasn't priced so extravagantly over our other top picks. We think for the extra money, you really are getting a superior product.
Conclusion
The Arc'teryx Kyanite is one of the most comfortable fleeces on the market. Its athletic cut makes it ideal for hiking, skiing, climbing, or any movement heavy activity. While it is quite warm for a fleece, it offers little protection from moisture and only moderate protection from the wind. It has an excellent weight to warmth ratio and accommodates layering over and under without issue. This is a great fleece for cool to cold weather pursuits. While it's priced on the higher end of the price spectrum, it will be hard to find a better-made fleece jacket.
