For a long time outdoorsmen could be split into two camps; those who use synthetic insulation, and those who choose down. Over the past five or ten years, however, the two categories have begun to feel like distinctions without a real difference. Outdoor brands have been incrementally improving each technology, effectively winnowing down the difference between the two. Now, with the Patagonia Micro Puff, it looks like the gap has been fully bridged.
This synthetic-filled jacket is not only more lightweight than its peers, but it is much, much warmer. Weighing in at 264 grams (the lightest jacket in its line), it actually boasts the best weight-to-warmth ratio out of anything Patagonia has released. That is thanks in large part to the use of PlumaFill insulation and a baffle structure that keeps an even loft and eliminates cold spots. In addition to these features, the jacket also uses a ripstop Pertex Quantum GL Shell that cuts through wind and resists water. To top all of this off, the jacket packs down into an easy to transport pouch. Now stop fighting, you guys.
