The Rab Borealis is a well-tailored light shell that delivers top-notch mobility and breathability. It's geared toward climbers that need something packable and fitted, but anyone active and mobile outdoors will appreciate this layer. Weighing barely over half a pound yet still able to provide a decent barrier against the elements, the Borealis impressed us across the board. It isn't going to keep you warm in severely cold or wet conditions, but the slim fit is perfect for layering under other pieces. And while it isn't particularly feature-heavy, all your bases are covered for most situations. Overall, this is a fantastic softshell and one we think the majority of climbers will find highly useful. Even better is the very friendly price tag, so we enthusiastically give it a Best Buy award.

Our Analysis and Test Results
The Borealis is a well-conceived lightweight softshell that is ideal for anyone needing to keep weight and extraneous material to a minimum. This jacket earns a Best Buy award because it's so well suited to being high on a rock face even when your bank account balance is way down low.
As much as we enjoy the Borealis, this isn't the category where it excels. This layer is unlined and very thin — ideal for many things, but not particularly warm.
Decently wind-resistant, this jacket also has a DWR-finish to help with water resistance. If you're engaging in an activity that keeps your heart rate up, you will be fine. But the moment those gusts get too intense, or it starts raining in earnest, you will be cold and wet. The fitted lines and minimalist weight of the Borealis make it ideal for layering under other things, but overall this is a better fit for mild weather.
This category is where the Borealis is in its element. We found this to be one of the most breathable jackets in our review.
Constructed from a lightweight single-weave fabric, this is the lightest softshell that Rab offers. Nothing about this layer feels stifling or suffocating, even when the sweat is pouring. From runs on chilly mornings to sunny crag days to hoofing it up a mountain trail, you will enjoy excellent ventilation in this sweet little jacket.
The Borealis achieves the perfect balance of being fitted without feeling constrictive. Jumping, running, climbing, and cartwheeling, all of it is easy and natural in this very mobile jacket. It has excellent stretch, and the well-executed slim cut means that there isn't excessive fabric bunching up or getting in the way of movement. It's a joy to wear when climbing, hiking, or playing.
The stretchy lycra-binding on the sleeve cuffs of the Borealis makes it easy to push them up and have them stay in place. And the fitted hood goes under a helmet instead of over it, which also aids in unrestricted movement. Of course, it's a bit of a pain if you want to remove it as you have to take your helmet off to do so, but we like this design more when not wearing a helmet because it never needs to be fussed with or adjusted — it just always fits. Almost everything about this jacket feels like a second skin.
Weight? What weight? We think the Borealis may be made out of feathers. Our size medium weighed in at just 8.3 ounces, almost the lightest in our review by a wide margin.
While little-to-no weight means that weather protection isn't as robust, it's a fair tradeoff for the right activities. If you're up on a rock wall or climbing a 14'er, you will appreciate the ultra-lightness of this layer.
We determined this metric by analyzing each jacket's features, style, durability, and ability to move between varied activities. The Borealis isn't a particularly feature-rich jacket, especially when stacked up against other models in our review, though the features it does have are well-conceived. It's highly durable, attractive, and appropriate for many warm-weather adventures where unimpeded movement and breathability are paramount. Rab says this softshell is inspired by the demands of big wall climbing, and we can see why. It's lightweight, well-fitting, easy to move in, and durable.
This piece has two zippered hand pockets that are long and placed high enough to almost be considered chest pockets. This makes them easily accessible while wearing a harness — they are also mesh-lined to aid breathability. The lightweight single-weave fabric is wind-resistant, DWR-treated, and UPF 50+. The drawcords on the hem are easy to use, and the fitted hood and chin guard provide great coverage around the face. The long slim fit is flattering and practical for all types of movement. Simple but smart, that's the Borealis.
Softshell jackets are, for the most part, less essential layers. They aren't potentially life-saving like hardshells, and they don't insulate as effectively as baselayers or fleece jackets. That being said, they can be highly useful for certain activities and add a true element of comfort. If you're on the fence about trying one, it's smart to start out with something simple and affordable. The Borealis is a great model to consider for this because it balances high performance with a friendly price tag. When you see a Best Buy award on one of our competitors, it always means that the value is high, and this baby is no different.
The Borealis is a fantastically easy layer to fall in love with. It fits like a dream, has stellar mobility and breathability, barely registers on the scale, and won't break the bank. It's no wonder it warranted a Best Buy award, especially for climbers who need a mildly protective layer that won't weigh them down or get in the way. While it's not a champion in the weather protection department, we know this is an article of clothing that you will be happy to own for mild weather applications or as part of a more comprehensive layering system.
