Best Ultralight Down Jackets

Ultralight down jackets a favorite among backpackers, climbers, and backcountry skiers who are counting every ounce. But if you’re not so extreme, these jackets are still great for boosting sleep systems and they fit really well in your pack.

Keep in mind, these down jackets are often minimal and come with thinner fabric to save the most weight. While these jackets can be really warm, they often require more care, so don’t expect to go bushwacking in these. Let’s check out some of the best ultralight down jackets.

The warm 1000 fill power down reduces weight while maintaining it’s thermal profile, all held together by lightweight but strong fabric. This minimalist design comes with no hood, no pocket, and no drawcord to save weight even more. While the minimalist design isn’t for everyone, the weight to warmth ratio can’t be beat.

The Montbell Plasma 1000 does fit a little snug, so if you’re looking to purchase this jacket, you might want to go one size larger than normal.

Patagonia Micro Puff Hoody

The Patagonia Micro Puff offers great water resistance

Weight: 9.3oz (264g)
Highlights: Synthetic with the warmth and feel of down
Best Price: Backcountry, REI

If you’re on the market for one of the best hiking hoodies, the Patagonia Micro Puff Hoody is something to consider. What makes this hoody so unique is that while it’s a synthetic jacket (warm when wet and highly water-resistant), it’s constructed like down, giving you an excellent warmth to weight ration.

What’s this jacket’s secret to keeping you extra warm? It uses PlumaFill insulation along with its special construction to preserve loft. This means there are a lot less cold spots where the down usually clumps. And like a real down jacket, it’s highly compressible and soft.

And the weight? 9.3 ounces (264 g) including the hood. What makes it so ultralight is the minimal design. While it does have two zippered handwarmer pockets and two internal pockets, it uses elasticized cuffs and hem to seal in warmth. And when you want to pack it up, it stuffs inside its left pocket with a reinforced carabiner clip-in loop.
