PrimaLoft Active Evolve Fabric Pros and Cons
The Backcountry Highliner PrimaLoft Air-Perm Fleece is made with PrimaLoft Active Evolve, a fabric clone of Polartec Alpha Direct (see below for our comparison between the two). Like PAD, PAE utilizes a lattice weave structure onto which a grid of lofted fleece tufts are sewn. Think of it like the guts of a thin synthetic puffy jacket, divorced from its shell. The lofted fuzzy tufts trap air to insulate, while the gridded pattern allows air to pass through for immaculate breathability.
PrimaLoft Active Evolve is much lighter and airier than traditional grid fleeces like Patagonia R1 or Polartec PowerGrid. People like to compare PAE and PAD fabrics to wearing a warm cloud. The primary advantages of this fabric is that it’s hyper breathable, high warmth-to-weight, and very quick drying. The primary disadvantages are that it has virtually zero wind resistance, low durability, and sheds fuzz.
To solve for the lack of wind resistance, we recommend carrying a lightweight windbreaker to use overtop as needed. Combine the two for a pseudo “build-your-own-puffy-jacket” effect.
On the sustainability axis, we love that it’s made with 100% recycled polyester and is OEKO-TEX standard 100 certified. However, it is a major offender in terms of shedding fuzz, which contributes to the microplastic pollution problem. These pros and cons kind of cancel each other out; we’ll give it a neutral score in terms of eco-friendliness.

Minimalist Features of Backcountry Highliner PrimaLoft Air-Perm Fleece
We recommend Backcountry Highliner PrimaLoft Air-Perm Fleece Hoodie over the quarter zip because hoodies are more versatile and the weightless fabric doesn’t lend itself well to a structural front zipper. The design of the hoodie is quite minimalist, though if we were designing it we would remove the kangaroo pocket and the self storage pocket. In general, less bells and whistles means the garment is lighter weight and has fewer failure points.
In this case, features include a kangaroo pocket, thumb loops, a stash pocket on the inside of the upper back, and elasticized trim around the cuff, hems, kangaroo pocket, and hood. While kangaroo pockets are preferable over individual hand pockets and still welcome, this material is so lightweight and stretchy enough that it doesn’t lend itself well to storing other objects. Of course you can put your other lightweight fabric gear inside, such as gloves or a beanie. But heavier items are out of the question and will overburden it and pull awkwardly.
The stash pocket works as advertised, but we don’t expect to use it much. In general, compressing objects into a compact ball shape makes them denser, harder to fit into small spaces, and take up more room than if they were stored loose. For example, three balled up jackets will leave large empty gaps of air between their spherical shapes when placed into a storage bag, whereas three loose jackets can be compressed smaller as there won’t be empty space gaps between them, and the bag itself will do all of the necessary compression.
One minor features complaint we have with Backcountry Highliner PrimaLoft Air-Perm Fleece Hoodie is that the elasticized wrist cuffs are too large and flop around awkwardly. Dear designers -because they’re elasticized, they’re allowed to be narrower at the opening, duh! We do appreciate the thumb loops though.

PrimaLoft Active Evolve Vs Polartec Alpha Direct
In this section, we compare the similarities, and relative advantages/disadvantages of PrimaLoft Active Evolve, which is used in the Backcountry Highliner PrimaLoft Air-Perm Fleece, with its chief competitor Polartec Alpha Direct. While both are excellent, top-tier ultralight fleeces, they each have relative advantages and disadvantages. We feel that PAD is overall slightly superior to to PAE, but don’t get lost in the sauce. They are very close to equal, and both are superior to 99% of other fleeces from an ultralight perspective. Compare this to more great options in our guide to Polartec Alpha Direct Hoodies.
