The Micro Puff Hoody combines an ultralight Pertex Quantum shell with PlumaFill insulation for the best warmth-to-weight ratio of any coat Patagonia have ever created, and the highest compressibility of any synthetic jacket. The new go-to insulation piece for mixed (and possibly miserable) conditions, the NetPlus shell is constructed from postconsumer nylon made from recycled fishing nets, and the insulation is recycled polyester, meaning this jacket not only does the job, but ensures it's doing its part too.
