City, State, and Country: Orange County, California,
getting into the outdoors scene camping while 4-wheeling
and day-hiking, I switched to backpacking in the early 2000's. I have backpacked
extensively in Utah, Wyoming and Idaho along with California, Pennsylvania
and Nevada. I have slowly been cutting my base weight to be able
to go longer in duration and distance. I have done
so mainly by using better gear and dumping heavy luxuries. I backpack year
round in all weather, and usually take a free standing tent
and a gas stove on all my trips. I love trying out new gear.

The Women's Nano Puff is marketed as a wind/water-resistant
pullover. That is very warm for its weight, super light,
highly compressible, no frills, and can be worn as insulation
or outerwear in cold climates. The manufacturer states that
it is the most versatile piece of insulation they make.
The Nano Puff is a quilt type of pullover jacket.
The PrimaLoft One polyester insulation is a single piece
of insulation that is quilted to the exterior shell of the
pullover. The (60 g) PrimaLoft One insulation is marketed
as being able to trap heat with efficiency, even when wet.
The shell is made of 100% recycled polyester (1 oz, 15 denier)
and has wind blocking and moisture shedding properties with
a DWR (durable water repellent) finish. The Nano Puff is
recyclable through Patagonia's Common Threads Recycling Program.
The Nano Puff is definitely a no frills pullover.
It has two zippers. One is for the main opening of the pullover
that measures a generous 12 in (30 cm) in length. The other
is for a left sided chest pocket that measures 5.75 in (17
cm) that runs lengthwise. This chest pocket turns inside
out to serve as a stuff sack for the Nano. I was able to
easily stuff the Nano in the stuff sack. There is a small
loop inside the chest pocket to hang the pullover (when it
is stuffed) on a clip or carabiner. The main zipper has a
plastic pull tab on the zipper and the pocket zipper has
a piece of cording attached to the zipper to make opening
and closing the zipper easier. The collar stands 3 in (8
cm) above the main body of the pullover. The cuffs and the
hem have elastic running through them to help prevent drafts.
That is it for the design features of the Nano. Very simple.
I checked out the Patagonia website prior to receiving
the Nano Puff. The website had images of the pullover
and detailed information of the properties and the
fabrics of the Nano Puff. The pullover looked nice
on the website, but not as impressive as it is when
I am holding it. It has a soft, silky shell and lining,
and it is super lightweight. I can not get over how
lightweight it actually is.
I received the Seaport color. I would consider this
to be a medium to dark blue-green color. I think
it is a beautiful color. The inner lining of the
jacket is a pale shade of blue-green that complements
the exterior shell color. I like the styling of the
Nano; it is not boxy or bulky. The Nano fits me perfectly
with just a little bit of extra room underneath to
wear a layer of moderate thickness or two thin layers.
The fabric care instruction tag inside the pullover
has the universal signs for fabric care and text
stating not to use fabric softener. The Nano should
be washed in water that is a maximum temperature
of 30 C (86 F) on a very mild wash setting, no bleach,
no iron, and tumble dry on low heat.
So far I am pleased with the Nano Puff. I have only
worn it one time on a windy, chilly afternoon while
rollerblading at the beach and I was comfortable
and warm. I have no complaints yet with this jacket.
But, I have yet to get it out into the field.
Mt. Woodson, California: The Nano
Puff was worn here while rock climbing and included
day-hiking, mild bushwhacking and belaying.
Mt. San Jacinto State Park, California: This
was a backpacking trip with clear skies and sunshine.
The high elevation was 9,000 ft (2,750 m).
The low temperature was 17 F (-8 C).
Bommer Canyon, California: The
Nano Puff was worn here for a full moon night hike
with clear skies. We hiked 3 miles (5 km). The
temperature was in the low 50's F (11 C).
Aliso Woods, Crystal Cove, Fullerton and
Whiting Ranch California: Here the Nano
Puff was worn before and sometimes after my mountain
bike rides. The temperatures were in the 50's F
(12 C) to the low 60's (16 C).
The Nano Puff was also worn on the beach path at
Huntington Beach, California while fitness walking

Rock climbing at Mt. Woodson, California
I have worn the Nano Puff in temperatures ranging
from the low 60's F (16 C) to 22 F (-6 C). I have worn it with
various layering combinations. For instance, on a recent backpacking
trip the Nano was worn over a light silk base layer and a synthetic
mid-weight Capilene layer. On this trip at around 23 F (-5
C) I found that I had to wear a shell over the Nano in order
to keep me warm. I had the neck zipped up and I was not chilled.
While hiking at night I wore the Nano with a light-weight wool
base layer top. Before and after cycling I would wear it over
a wool or synthetic cycling jersey.
On one of my night hikes and while hiking to climbing
locations, I over heated in the Nano, even with the zipper
open. I removed it and stored it in the storage pocket. I was
able to easily store the jacket in the pocket without any struggle
to fit it in there.
Sometimes I wish the Nano had hand pockets, especially
at base camp. I know this would add extra weight and bulk to
the jacket. I am learning to live without the pockets; I am
just thinking it would be a nice feature. When I have the chest
pocket full of odds and ends it gets kind of bulky and it looks
weird. But, it is functional. The pocket is deep enough to
hold items that I want to have accessible, quickly. Such as
extra gloves, lip balm, snacks, tissues, and my MP3 player.
To me the Nano Puff appears slightly bulky at the
bottom. But, it does not feel bulky at all. While wearing the
jacket I have full movement of my shoulders, the sleeves do
not ride up and they are a perfect length for me. However,
when I am taking the jacket off, I feel as though I am limited
with my shoulder motion and I have to squirm in the shoulder
I have washed and dried the Nano three times by
following the care instructions on the tag. The jacket handled
washing and drying well with no stretching or shrinking.
One of the quilting threads has come become unstitched
at the thin wrist cuff. This tread has pulled out about 3 stitches.
I am going to contact customer service about this issue. Since
the tread started to come out at the cuff I am thinking this
is a manufacturing defect as the cuff is not torn or damaged.
I will just have to see what customer service says.
The Nano was worn in a light misty rain and was
exposed to ground snow and water while at base camp. When exposed
to light water the exterior appears to be wet while the inner
lining remains dry. The jacket was not exposed to heavy rain
or snow during the testing period as I did not want the jacket
to wet out since it is not waterproof.
I am pretty impressed with the Nano Puff. It packs
down small and gives me plenty of warmth down to about 23 F
(-5 C) without needing a shell layer on top.
Mt. San Jacinto State Park,
California: This was a snowshoeing day trip
with windy conditions. The high elevation was 9,400
ft (2,865 m). The high temperature was around 48 F
Orchard Hills, California: This
was a night hike on Irvine Ranch Conservancy Land.
The low temperature was in the 50's F (15 C). The Nano
was worn here over a thin silk layer and a moisture
wicking shirt. This was a 3 mi (5 km) hike.
Crystal Cove State Park,
was a hike along a trail on the beach in and out
of the tide pools. The elevation ranged from sea
level to 60 ft (18 m). The temperature was in the
low 50's F (10 C). There was a misty rain at times.
This was a 5 mi (8 km) hike.
Black Star Canyon and
Maple Springs (Cleveland National Forest), California: The
Nano was worn here after mountain biking. Lucky for
me I had it in the car. The temperatures were in
the 40's F (4 C). At Black Star Canyon it was misting
rain and at Maple Springs it was raining lightly.
Orchard Hills, California: This
was a night hike on Irvine Ranch Conservancy Land. The
low temperature was in the 50's F (15 C). The Nano was
worn here over a thin silk layer and a moisture wicking
shirt. This was a 3 mi (5 km) hike.
Death Valley, California: The
Nano was worn here in the morning and the evening while
car camping. The elevation was approximately -180 ft
(-56 m) and the low temperature was 49 F (9 C).
in the Field
I contacted Patagonia customer support
in regards to the pulled thread on the sleeve. The representative
was friendly and helpful. I was told that it would take approximately
6 weeks to receive the jacket back from repair. I decided
that I could easily stitch and reinforce the pulled thread.
So, I bought some matching thread and stitched four stitches
on the sleeve, and to this day it has held up well. Some
of the other threads on the quilting are fuzzy, especially
on the sleeves and the shoulders. The recycled polyester
material of the Nano is not showing any signs of wear, even
after rubbing against bushes and shrubs while hiking. I am
concerned about the fuzzy threads. This makes me think the
jacket is more delicate than the other jackets that I own.
I have washed and dried the Nano following the care instructions
about five times since receiving it and there are no signs
of stretching or shrinking.
Since I have been wearing the Nano in temperatures
in the upper 40's F (4 C) and in the 50's F (15 C), I have
not missed the lack of hand pockets. However, I still think
hand pockets would be a nice addition to this jacket, especially
when it is worn in colder temperatures without a shell on top.
When I get too warm wearing the Nano, I stuff
it in the chest pocket (that is a stow pocket too) and toss
it in my pack. It is still very easy to stuff in the stow pocket,
with no struggle at all. I wish all my jackets were like this.
The Nano is not waterproof; it is marketed
as having a DWR (durable water repellent) finish. I hiked in
a misty rain while wearing the Nano and it did not wet out.
But, in a light rain it wetted out on the shoulders and the
sleeves. It was raining lightly at Maple Springs while I was
mountain biking and I was not smart in my clothing selection
that day. I was cold because my socks, legs, and shorts were
wet. I decided to change into something dryer after my ride
before packing up my vehicle. I had the Nano in the car and
I thought I would put it on to help warm me up. While packing
up the car I started to feel wet on my shoulders and my
arms. The Nano got wet all the way through in these areas.
I wore the jacket home, wet; because I needed the warmth since
my core was cold. When the Nano becomes wet the water does
not seem to bead off even with the DWR finish. And I would
not consider the Nano to have much of a wind blocking property.
In a light breeze I could not feel the air penetrate through
the fabric, however in a consistent wind or in wind gusts I
could feel the air penetrating through the fabric.
During the long term report I layered silk
and wool tops beneath the Nano and I was warm. While hiking
uphill at Orchard Hills I became uncomfortably warm while wearing
the Nano. I did not want to take it off because I knew I would
be going back downhill soon. It felt steamy inside the jacket
even with the zipper opened. After reaching the top of the
hill it was dark and we had to hike back to our starting point.
I was glad I did not take off the Nano as it was getting chilly.
My clothes underneath the Nano were not excessively wet from
sweating. There were a few damp areas, but that was it.
In the chest pocket I am still only placing
a few small items in it. I do not like the look of the added
bulk when I have larger items in the pocket. Generally I put
my lip balm, a few tissues, and my MP3 player in the chest
I love the Nano! It is one of my favorite
insulating jackets. One of my favorite features of the Nano
is how light weight it is. It packs down small and is versatile
enough to wear additional layers as needed to keep me warm.
I like the cut and the styling of the Nano, and I just love
the color. I get so many complements on this jacket when I
am wearing it on the trail. Now, I would love it even more
if it had hand pockets. I hope the Nano holds up for many years.
- Fits perfectly
- Packs small
Things That Are So-So:
- A thread is undone at the wrist sleeve
- The jacket is a little tight in the shoulder
area when I am trying to pull it off
- No hand pockets
concludes my reporting on the Nano Puff Pullover.
Thank you Patagonia and backpackgeartest.org for providing
me with the opportunity to test this product.
