Our Analysis and Test Results
The Rab Borealis is a highly versatile option that can be worn all day, even as temperatures fluctuate. While it needs to be paired with other jackets for better weather protection, it's easy to layer in various ways. Best of all, this softshell comes at a more approachable price than much of its competition.
Performance Comparison
Weather Protection
Weather protection is worth 30% of the total score of the Borealis. We tested this metric by spending weeks in the field with each product, taking detailed notes related to warmth and wind/water resistance. Then, we performed a series of objective tests, starting with a 1-minute shower test and measuring the surface area of wet spots on the layer underneath. We also boiled water, put it in a bottle, tucked it into the jacket, and measured the time it took for the water to dip below 170 degrees Fahrenheit. The Borealis came in towards the bottom of the pack in this metric, among the least protective.
During our shower test, we got soaked. It almost felt like we didn't have a jacket on at all towards the end of the 1 minute. We were grateful this option dried so quickly, and it still offered some decent wind protection in field testing. And given its lightweight and breathable traits, it wasn't a surprise when this jacket only kept the water bottle above 170 degrees for 21 minutes. At the end of the day, this option offers a minor amount of protection from the elements, but not a lot. Fortunately, it layers well with other garments that can add warmth and water resistance.
Breathability
Breathability is one of the reasons a softshell will be chosen over other types of jacket, so we gave it 30% of the total score of the Borealis. We examined this metric first by spending weeks in each option across many different outdoor sports, taking detailed notes of our findings. Then, we performed a 45-minute cardio circuit with each jacket on, measuring the surface area of the sweat spots that appeared on the underlayer by the time we were done. This softshell came in at the front of the pack in this metric, demonstrating breathability as one of its greatest attributes.
The Borealis is made with the thin, Matrix single weave fabric from Rab and excels at breathability. Outside of the hottest days of summer, we could keep this jacket on all day in mountainous environments, simply adding an extra layer if we got cold or if the weather turned stormy.
The two large chest pockets are mesh-backed, allowing for incredible ventilation on higher output missions. During our objective sweat spots test, we only had 18 square inches of wet areas on our underlayer, further placing the Borealis at the top of the pack. This jacket belongs in your shopping cart if ventilation and breathability are your priorities.
Mobility
If you can't move freely in your garment, what are the odds you'll ever wear it? We gave mobility 25% of the total score of the Borealis. To test this metric, we first spent dozens of hours in each layer, noting our mobility findings. Then, we performed a specific list of movements in a controlled environment, measuring the jacket's waist lift and noting any restrictive areas. We also took note of any excess fabric bunching, as that can get in the way of many activities. The Rab Borealis came in at the front of the pack in this metric.
The Borealis strikes a great balance between slim fit and range of motion, offering excellent freedom of movement without excess bunching. However, the only adjustability one can make in this garment is at the hem, so if this jacket doesn't quite fit you, another option may be a better choice. Also, the hood of this softshell fits underneath the helmet, which can be an acquired taste. Besides a few considerations, this is an excellent option for mobility.
Weight
We gave this metric 10% of the total score of the Borealis. We simply tested this metric by placing each softshell on the scale and recording our findings. This option came in near the lightest weight options in the lineup.
The Borealis is an excellent layer if weight is a concern. At 9.7 ounces, this is a layer you're unlikely to feel in your backpack or while you're wearing it. This option also boasts great packability and can even zip into one of its chest pockets, allowing one to clip the layer to their harness or backpack.
Versatility
Versatility is worth 5% of the total of the Borealis. We simply investigated the various activities and seasons each layer could be used for. We also examined how well one could fit a layer under or over the Borealis. This option showed impressive flexibility in use.
While the Borealis isn't the most weather-protective, it can handle warmer days and easily accommodates other layers if the season or weather gets cold and stormy. Thicker softshells can't be made lighter, potentially limiting their versatility, while lighter softshells offer flexibility when it comes to layering. This garment also has a decent, clean aesthetic for around-town hangouts.
Should You Buy the Rab Borealis?
With top scores in multiple metrics, this jacket offers a significant amount of value, especially when considering it's twice as inexpensive as some of the competition. Rest easy knowing the Borealis carries your hard-earned cash very far. This option boasts excellent breathability and mobility, making for an incredible companion to your mountain adventures.
What Other Softshell Jackets Should You Consider?
The Black Diamond Alpine Start Hoody is one of the lightest softshell jackets you'll ever find. With decent performance across all metrics besides weather resistance, it's a worthy alternative. We also recommend the Rab Kinetic 2.0 if water resistance is a priority. It adds only a few ounces of weight compared to the Rab Borealis but dramatically levels up the weather protection.
