Patagonia Micro Puff Jacket Review


If you’re looking for a jacket that will keep you warm and dry in any weather, the Patagonia Micro Puff Jacket is a great choice. It’s a lightweight, synthetic insulated jacket that can be packed away and used year-round.

It features a 0.7-oz 10-denier 100% nylon ripstop Pertex Quantum shell with a DWR (durable water-repellent) finish. The hoody also boasts discontinuous patent-pending stitching and PlumaFill synthetic insulation that mimics down, but it isn’t as lofty.

Warmth-to-weight ratio

Patagonia is known for making some of the best gear, and its Micro Puff Jacket is no exception. The company’s patented PlumaFill synthetic insulation combines the lightweight warmth of down with the reliable weather resistance of polyester.

The jacket’s weight and warmth-to-weight ratio are unmatched. It’s lighter than many synthetic options.

This means that it’s an excellent choice for backpackers and adventurers who are looking to save weight without sacrificing warmth. It also works as a mid-layer for colder days on the trail or as a light ski jacket in the mountains.

The jacket’s shell is made from a thin 10-denier Pertex Quantum fabric treated with a durable water-repellent finish. This allows for supreme breathability, waterproofness, and wind resistance.


Patagonia Micro Puff Jackets are an excellent choice for an ultralight, warm, and packable jacket. They are also durable and weather resistant.

The Patagonia Micro Puff Hoody is one of the lightest synthetic insulated hoodies on the market, weighing just 9.3 oz in size large. As a layering piece, this makes it ideal for three-season backpacking, day hiking, and colder weather conditions.

It features a lightweight Pertex Quantum shell with a PFC-free, durable water repellent (DWR) coating that surprisingly sheds light to moderate rain. It also has minimal stitching and a continuous insulation design that limits vulnerability to wind gusts and is comfortable to wear even when wet.

This jacket uses PlumaFill, a synthetic insulation that mimics the warmth of natural down. It’s made from strands instead of individual fibers, which helps trap heat, reduces points of weakness (no escaped feathers!), and keeps you warm when wet.


The Patagonia Micro Puff Jacket is one of the most packable synthetic jackets on the market, and it packs down to around a Nalgene size! This makes it perfect for packing into a rucksack when you’re on the go.

The Micro Puff Jacket uses a synthetic insulation called PlumaFill which mimics the down structure but with a much higher warmth-to-weight ratio. It also stays warm when wet.

This is an excellent feature because natural down clumps up when wet, so it doesn’t trap as much heat.

The Micro Puff jacket is a solid all-rounder for backpackers and climbers who want to keep warm without the weight and bulk of traditional down insulators. It also has a few unique features that make it stand out from other synthetic jackets.


Patagonia has a strong track record for making comfortable gear, and the Micro Puff Jacket is no exception. It’s a bit of an odd shape, as it doesn’t have the sleek profile of many alpine-cut pieces, but it’s roomy enough to slip over another layer, and it seals well with elasticized cuffs and hem.

The insulation is also a step above the competition, called PlumaFill, and is made from long, thin fibers (think hair-like) that are wrapped around a stabilizing fiber. This creates highly effective lightweight and lofty insulation and holds warmth well, even when wet.

While the Micro Puff is an excellent piece for ultralight weight backpackers, we didn’t find it as warm as some other synthetic insulated jackets. But it’s worth considering if you’re looking to save weight and can’t afford a more expensive down jacket.
