The bottom line: The Rab Flux Pants are a comfortable midweight baselayer fleece pant that offers excellent warmth at a light weight and a reasonable cost.

 


The Rab Flux pants are an economical option for winter running. Ethan Rambacher.

The Flux Pants are meant for cold weather, and you can tell when you put them on. Made of polyester fleece, they feel soft and warm the instant you put them on. The inside is brushed, so it is extremely soft and comfortable. They are also quite stretchy, which makes them fit great. They definitely have a slim fit.

The fleece material is just a bit thicker than a typical running tight, which definitely gives these pants some extra warmth. However, the Flux pants still have quite a bit of stretch in them, which makes them great as a baselayer for running, winter hiking, ice climbing, yoga, basically anything active.

Because these are polyester pants, they wick moisture away from the skin and don't sap too much heat from your body if they get damp. However, if you are hiking with these, you'll probably want to use them with an outer shell pant. I find them perfect for winter hiking below 20-degree conditions with soft shell pants, or in warmer conditions if it is a less strenuous hike. They're also perfect for running in a wide range of cold temperatures, below 30 degrees or so (depending on your preferences). And while these pants are certainly not windproof, they do offer some protection from light winds.

Overall, the Rab Flux pants are versatile, comfortable, and warm at a reasonable price, and I highly recommend them for cold weather activities.
