Patagonia Nano Puff Hoody Review

The Patagonia Nano Puff Hoody receives middle-of-the-road scores in all performance rating metrics. Patagonia has stuck with their classic, generalist design for this model and has also introduced other options when breathability is key. The Nano Puff compresses very small into its chest pocket and remains an excellent and classic choice for clipping to your harness or carrying while backpacking and hiking, and will save you a bit of cash when compared to other Patagonia synthetic options.

Performance Comparison

Springtime in the mountains can be cold, then hot, then cold again! It's a good idea to have a lightweight insulator like this one on hand.

Warmth

This insulated jacket uses 60 g/m2 Primaloft Gold insulation Eco held in place with quilted squares. All the stitching in these squares lets some air pass through, which is nice if you're looking for some breathability, but not great when the winds start howling. This insulation compresses better than Coreloft and Polartec Alpha and will maintain its warmth when damp. An elastic cinch at the hem lets you seal in warmth, but the loose wrist cuffs let heat escape. We found this model a bit warmer than the majority of the active insulated layers that now dominate the market.

Weight & Compressibility

This is one of the heavier of the lightly insulated pieces we tested. At 12.7 ounces for a size small, it's a bit heavier than other smalls we tested. What the Nano Puff Hoody does offer, however, is excellent compressibility. It stuffs tightly into its chest pocket, creating one of the smaller stuffed packages we tested. This makes it very popular for multi-pitch climbing. Having a jacket with a low stuffed profile is great for squirming through chimneys in Yosemite and Zion, but keep in mind that the smaller the stuffed size of a jacket, the longer it takes to pack away. Stuffing this thing into its pocket certainly takes a hot minute.

This is the OG stuff-in-the-pocket puffy, and it set the standard in packable puffies for the last decade.

Comfort

This insulated jacket's minimalist features make it a lightweight and functional piece, but it earned a relatively low comfort score overall. Slippery fabrics allow it to layer well under a shell, but those same fabrics feel sticky if you start to sweat. Though designed with climbing in mind, the short hem length tends to ride up when raising your arms. Patagonia uses a snug-fitting, non-adjustable hood design that fits well under a climbing helmet.

The included clip-in loop makes this jacket ready for long climbing routes.

We appreciated the comfortable microfleece patches that form a "zipper garage" when the jacket is fully zipped up against the face. Two deep, zippered hand pockets lined with slippery nylon and an internal zippered pocket on the left chest provide ample storage. The jacket stuffs into this chest pocket, while the main zipper and the hand pockets have easy-to-grab zipper pulls. The wrist cuffs are simple and straightforward, but not as snug as we would like. The hem cinch has one cord lock located on the right side.

This jacket has conveniently large zipper pulls and a popular quilted pattern.

Weather Resistance

This is one of the light models we would call fairly weather resistant. While the outer shell is sewn-through, the interior nylon liner blocks wind that penetrates the seams. While the DWR on the Puff's outer fabric beads water well, there is tons of stitching sewn through it. You definitely want to have a light shell layer handy if you're heading out in threatening weather. We have found that models with nearly continuous outer fabric perform much better when the rain and wind rolls in, and yet the Nano Puff's liner fabric resists the wind once it comes through the exterior.

Breathability

This is not one of the more breathable models we tested. Both the outer shell fabric and interior liner contribute to blocking airflow. Many other jackets use advanced insulation and stretchy permeable fabrics that create excellent breathability for high-energy use and are thus better choices if breathability is one of your top concerns. The Nano Puff functions best as a lightweight belay jacket.

As technology has advanced over the years, this has become more accepted as a "lifestyle" jacket than a performance piece, but it's still highly effective insulation for the backcountry.

Value

While not the most expensive Patagonia insulated jacket you can buy, there are much better values to be had. Still, we think it's cool that the Nano Puff is constructed from so much recycled material, and it is backed by Patagonia's excellent warranty. If you love the Nano Puff design, but want to save some money, check out the non-hooded and pullover versions.

This jacket is loaded with features, including a cinch cord at the hem to seal in warmth.

Conclusion

The Patagonia Nano Puff Hoody is a classic generalist jacket. It stuffs really small and is great for clipping to your harness or toting in your backpacking kit. That said, lightly insulated jackets are quickly becoming more specialized. We prefer more breathable options for high-energy use and more wind and water-resistant options for multi-pitch climbing.

This jacket is available in a ton of colors, brights, and also low profile colors like gray and black.
