The Rab Kinetic Plus provides a nearly unparalleled level of mobility and freedom of movement. It also offers average breathability and a cozy interior feel. This, coupled with a trim fit makes it perfect for any high-energy activity.
Our Top Pick for its unparalleled level of stretch and freedom of movement, the Kinetic looks and feel more like a softshell than a hardshell. Photo John Yarnall in a Kinetic above the Luna Creek Cirque in the Northern Pickets, WA.
The Kinetic Plus uses Rab's propriety Proflex waterproof membrane; it has an ultra stretchy knit polyester exterior and a plush, wicking interior, complete with brushed polyester fabric on the inside.
The Proflex membrane is a PU membrane, which is one of the main reasons this model is so impressively stretchy.
For such a stretchy rain jacket, this model provided exceptionally good DWR. However, it was just so-so for prolonged outings in wetter conditions but still performed better than many price-pointed models.
Its overall weather resistance was excellent, especially in the first stages of testing, where the Durable Water Repellent, or DWR, was astoundingly good. After a fair amount of wear, we remained dry in most cases; however, during extended periods in wet conditions, such as hiking up overgrown trails immediately after a rainstorm, the exterior fabric's DWR started to slightly wet out. With that in mind, the Kinetic Plus performed better than more basic non-laminated models like the Marmot PreCip, The North Face Venture 2, or Patagonia Torrentshell, and was similar in water resistance performance to the Outdoor Research Helium II. With all that said, if we knew were going to get rained on for extended periods, we preferred a burlier rain jacket, like the Arc'teryx Zeta SL.
All of our testers appreciated this model's low profile cuffs which kept the water out but also resisted snags while thrashing through brush.
We appreciated several of the small features built into this jacket's design, which kept the elements out while playing in foul weather. Features like the low profile Velcro cuffs, which were extremely comfortable, rarely snagged and kept the wetness out better than most when our hands were above our head.
This model performed average overall for weather resistance, but nothing to write home about. Photo: While descending from a winter ascent of Mount Whitney in blustery conditions, the Kinetic Plus kept out the wind.
The hood employs a unique design that we haven't seen in previous years. It has two layers to it; the first and outer most layer is like any hood you've seen which has a brim. The second is an inside layer that wraps above the wearer's forehead and acts like a gaiter of sorts, with an elastic cuff that keeps it in place.
The hood maintained excellent peripheral vision and its unique double-layered design is effective and comfortable.
Our testers were skeptical of this design before using it; they thought it would be uncomfortable and bordering on claustrophobic feeling. However, after extensive use, it proved to be neither. To our surprise, this design was extremely comfortable and kept the wetness out while moving with the tester, maintaining some of the best peripheral vision in our review.
This photo highlights the double-layer hood design, with the inner elastic hood, which goes over the top of the wearer's forehead. We were skeptical of this design but were surprised at how uncumbersome it felt and how well it allowed the hood to move with our heads.
The hood doesn't feature an elastic cinching mechanism. Instead, it uses a single Velcro tap on the back of the hood which can be used to tighten the hood. We usually don't find similar designs to be incredibly effective, as they have the probability of limiting peripheral vision. This design, however, complete with an internal hood gaiter, proved otherwise. While this model is undoubtedly geared toward climbers, it's worth noting that it doesn't fit over a bike or climbing helmet, but is low profile and comfortable enough that it can easily be worn underneath one.
Despite the basic adjustment, the Kinetic's hood was one of our favorites thanks to the double-layered design. It was also one of the better models at maintaining good peripheral vision.
Breathability & Venting
The Kinetic Plus is one of the more breathable models in our fleet.
Its PU laminate is more breathable than coated membranes and many ePTFE models (Gore-tex and eVent fall into this category, though their water resistance is generally longer lasting).
Testing each model's breathability and a side-by-side breathability test. Overall we found the Kinetic to be one of the more breathable models in our review; its air permeable design allows it to keep moving moisture, even after you've cooled down.
Its brushed polyester lining is soft and did not feel clammy against our skin. The Kinetic Plus is significantly more breathable than the Marmot Precip and Patagonia Torrentshell, and similar to the Outdoor Research Interstellar and REI Co-op Drypoint GTX, which both use Gore-Tex Active.
The Kinetic Plus doesn't feature any real ventilation options. Technically speaking, its two pockets can be used to dump heat and moisture, but it is a pretty minuscule amount. When determining the significance, our testers found that breathability is far more important than venting; for example, if it's pouring or you're walking on a damp, overgrown trail, opening up your vents is a quick way to get wet.
The Kinetic offers better than average breathability. It's worth noting that is one of the slimmer fitting models in our review; folks who may be between sizes should consider sizing up.
Comfort and Mobility
Mobility and freedom of movement set the Kinetic Plus apart from other models in our review.
Stretchier than most, including the Black Diamond Fineline, this is truly an important attribute.
The Kinetic was the stretchiest model in our review, offering incredible freedom of movement.
In addition to an excellent range of motion, the Kinetic Plus has one of the best feeling interior fabric of any model in our review. It feels amazingly soft, even against bare skin. This fabric is more of a wicking fabric, whereas the interior materials of most rain jackets are primarily designed to protect the waterproof membrane, which has been sandwiched inside.
The ultra-stretchy fabric of this jacket allows for an exceptionally good range of motion for whatever the task at hand may be.
The Kinetic Plus has one of the most athletic fits, which means it has a slimmer fit; fortunately, we could still fit a thin fleece (such as a Patagonia R1) under our size medium, which is our main tester's typical size. Featuring a slim fit in the sleeves, elbow areas, and torso, this fit is different than most models in our fleet, as we could fit a thin fleece and often, a light puffy coat under other models. If you're looking to buy this jacket to layer underneath, you'll want to consider sizing up, especially if you are in between sizes.
The zippered hand pockets are slightly elevated, which keeps them out of the way and accessible with low profile pack waist belts. Bulkier backpacking pack waist belts will overlap a little (this depends a little on the user), but the zippers are low enough profile that we didn't feel any pinching pain. Since the pockets open from the top, they are still partially accessible when wearing a pack.
The pocket design of the Kinetic Plus is no frills. It sports two front pockets, which split the difference between being more comfort-focused (lower) and more function focused (higher and out of the way of a waist belt). While we would like to see such an activity-focused model sport even higher pockets, the pocket design doesn't interfere with a harness. Its zippers are low enough profile to minimize any discomfort you might get from a pack's hip belt. The pockets are mesh lined and cozy on your hands, but if left open, can acquire water on the inside.
We confirmed the weight of the Kinetic Plus, which rolls in at 11 ounces, or 0.68 pounds.
While it isn't quite as light as some minimal models, which checked in around 6-7.5 ounces, it's significantly more durable and offers better breathability and a superior range of motion.
The Kinetic has a hood closure but it is small and easily comes undone.
The Kinetic Plus is plenty suitable for most outdoor activities, as it's a jacket that will handle backpacking, hiking, ski touring, and alpine rock climbing.
It's similar in durability to the Outdoor Research Interstellar but not nearly as tough as the Arc'teryx Zeta SL, Outdoor Research Foray, or the Marmot Minimalist.
While this model didn't reverse into a pocket like many models in our review, we liked that it comes with a stuff sack. The stuff sack did an excellent job of compressing the jacket.
The Kinetic Plus comes with a small, separate stuff sack and compresses slightly smaller than average models in our review.
We appreciate the included stuff sack, which performs reasonably well in compressing the model down. Several other rain jackets included stuff sacks that are near twice as big as they need to be, something that makes it easy to pack, but doesn't minimize the volume it takes up in your pack.
A nice bonus of the stuff sack is the relatively beefy clip-in point, which makes it easy to attach to your harness to carry along on multi-pitch routes in the event of rain or afternoon thunderstorms.
The Kinetic Plus has a small reinforced clip-in point which can be clipped to a harness for climbers wary of a change in weather or an afternoon thunderstorm. It packed down slightly smaller than the Outdoor Research Foray or Arc'teryx Zeta SL.
With a retail price of $230, this jacket is on the more expensive side of jackets, though more in tune with the price of performance-oriented models. Similar performing models, like the Outdoor Research Foray ($215), has comparable ranges, while the Kinetic Plus costs less than the Patagonia Cloud Ridge ($250), or the REI Co-Op Drypoint GTX ($250). For the price of the Kinetic Plus, you'll get an incredibly stretchy fabric, which provides some of the best range of motion of any model in our review plus above average breathability, excellent storm-worthiness, and a rad, effective hood design. Plus, it is still less than the Outdoor Research Interstellar or the Arc'teryx Zeta SL (both $300).
This model's ultra-stretchy fabric offers some of the best mobility and range of motion of any model we tested. It's also fairly lightweight and boasts decent breathability, which makes it a perfect option for activities with a higher aerobic threshold.
If unencumbered freedom of movement and maximum mobility are priorities for your rain jacket, then the super stretchy Rab Kinetic Plus should be a strong consideration. It's not the best model for spending extended periods in heavy downpours, where this model would consistently wet out a bit faster than similarly priced models. However, for more active endeavors where rain is a possibility, its breathability, athletic fit, sweet hood design, and cozy feel make it an excellent choice.
