The R1 Air combines hollow-core yarn and a unique zig-zag weave that serves a dual purpose. For starters, it’s incredibly lightweight and thin, making it as perfect as a solo garment as it is for layering.
Second, the structure was carefully designed to capture warmth when needed. Better still, it’s breathable when you need to cool off, and it’s quick-drying.
In short, it’s not just a hot box; it’s designed to be warm in the cold and cool in the heat, making it a serious dual-threat.

In pursuit of perfection
Now that you know what makes the R1 Air such a groundbreaking evolution of the fleece, you might wonder what’s different about this upcoming version. Much of what makes it remarkable remains — which is a very good thing.
However, in pursuit of making it the best it can be, Patagonia has made some seemingly incremental tweaks. But that doesn’t mean they’re small; these adjustments help inch it ever closer to being perfect.
