In this neck of the woods, pretty much everyone and their sister has the Patagonia Micro Puff Jacket and they wear it nine months out of the year. This season the Micro Puff becomes even more environmentally sound without losing any of its functionality - the shell and lining are now made of 100% post-consumer recycled NetPlus® nylon ripstop, which reuses old fishing nets to keep them out of the ocean and the gastrointestinal tracts of sea animals, and the insulation is 100% recycled Polyester PlumaFil. Not only does this jacket pack a big thermal punch for something that layers so easily, it packs a reduced environment punch so you feel good about owning it.
