The Best Aerobic Softshells

The soft shell category isn’t defined clearly. Original designs prioritized breathability and quick drying over weatherproofing, but currently, the category can span garments that functionally act as hard shells to single layer, highly breathable wind shells. The items chosen for this test were not primarily insulators, nor were they hard shells. Compared to prior tests (where the jackets were truly just shells), the category has widened drastically in functionality. Some provide the same weather protection as classic hard shells, but offer more breathability, softer hand, and better drape. Others add warmth and can act as both the outer shell and a light insulating layer.

Softshell jackets are tested across a broad range of activities and weather conditions to represent the widest combination of breathability and weatherproofing requirements, durability, compressibility needs and featured usage. Aerobic training, hiking, backpacking and all forms of climbing can all be utilized to test these garments, subjecting them to a wide array of stressors.

Breathability was the original primary design goal of the first soft shells and is still a leading consideration, as getting wet from the inside can be just as serious a problem as getting wet from the outside. Durability is extremely important; in certain situations, failure of a layer can be catastrophic and a large part of perceived value centers around how long a garment lasts. Weatherproofing can be at odds with breathability, but in dire situations, this is the only factor that may matter. Until the miracle fabric exists, breathability and weatherproofing will have an inverse relationship; as one goes up, the other will go down. Fit/Comfort is highly personal, different body proportions and preferences steering evaluations of this department. Fit/Comfort will always be notated with the general dimensions of the tester along with any obvious anomalies to fit or comfort. Compressibility’s importance depends on the packing situation, but more compressibility will never be negative. A jacket’s features can alter the effectiveness of the garment for each specific use; aerobic training demands a vastly different feature set than an alpine climber. Having too many features when not required affects factors such as compressibility, while not having a required feature when needed can be frustrating at best and dangerous at worst.

What Is A Softshell Jacket?

Softshell jackets have morphed into numerous functional variations in the short lifespan of the category. The original designs accepted that waterproofing and breathability were opposing sides of an equation that had no real solution; the softshell gave up on waterproofing to provide a windproof, insulating and water resistant “shell” that was superior at preserving the microclimate next to the body in conditions that didn’t involve heavy rain. A windproof, yet air permeable shell material was combined with a wicking and insulating fleece type inner material. Avoiding moisture from the inside became the priority over avoiding moisture from the outside, and even light precipitation wasn’t an issue as wicking materials and high vapor transfer rates allowed body heat and convection to dry the garment in short order. Even when wet, these original designs felt dry as the inner liners were designed to have little contact with the body.

The softshell category has evolved in several directions, and the primary function of the category is hard to define. It seems as any jacket that can be worn as an outer layer that isn’t a classic, non-insulating, waterproof nylon shell is tagged as a softshell. Modern versions of the original designs remain, some adding additional waterproofness. Some have stripped down to a soft handed windproof and water resistant single layer shell. Some have jumped the gap to have the same waterproofness as a hard shell, but promise better breathability and softer, quieter and more pliable fabric.

The original opposing factors of waterproofness and breathability still exist. The manufacturers still have to choose a position along the spectrum to occupy. This test involved jackets that are on the far ends of the spectrum as well as innovative attempts at being the happy medium. The main factor in the decision of which softshell jacket is best involves figuring out what part of the waterproofness vs. breathability range your conditions and activity demand.

Pricing varies widely; fabric technology drove much of the pricing. The newer fabrics that claimed a high degree or total waterproofness while still being somewhat breathable were the most expensive, while the simpler fabrics that relied on only a DWR coating to resist water but were more breathable tended to be less expensive.
