The best warmth for weight jacket we’ve ever built, the Micro Puff Hoody delivers ultralightweight, water-resistant, down-like warmth with PlumaFill synthetic insulation—a revolutionary featherlight down alternative.

Patagonia says:

It’s like down, only better—our Micro Puff Jacket uses a revolutionary, feather-soft synthetic insulation with an unprecedented warmth-to-weight ratio. The groundbreaking PlumaFill insulation (65-g 100% polyester) is phenomenally light and compressible, offering down-level warmth that still traps your heat when it’s wet. A nylon ripstop Pertex Quantum shell, with a DWR (durable water repellent) finish, blocks wind and snow. The garment’s design maximizes performance and minimizes useless fluff. Features: zippered handwarmer pockets (the left pocket doubles as a stuffsack with a reinforced carabiner clip-in loop), a pair of sleek internal drop-in pockets (made without excess, using the backside of the handwarmer pocket bags), and elasticized cuffs and hem.

Patagonia's Micro Puff Jacket is the lightest jacket in our synthetic insulation range. Patagonia boast that their unique PlumaFill insulation has a warmer warmth to weight ratio than down. It's hard to argue either way when the jackets are so light but the Micro Puff definitely heats up quickly and effectively.

The PlumaFill insulation is Patagonia's masterpiece in synthetic insulation. Everyone is trying to replicate the warmth and weight of down while reducing the negatives associated with its performance, particularly when wet. The insulation is unique in that it is the most compressible insulated jacket Patagonia produce, along with a unique construction that prevents shifting, clumping and cold spots. The loft retention and water resistance last for life of the jacket and with Patagonia's excellent background of durability and repairing kit you can be assured this jacket will last.

The stitch design that keeps the PlumaFill in place is also an nice aesthetic feature. In addition to the super-light insulation, the outer fabric is high quality Pertex Quantum which gives it a lightweight but durable finish. The overall weight of the jacket is further reduced through the use of elasticated hem and cuffs. Two zip hand pockets are a good size and they double up as internal drop pockets giving additional space.
