I've been an intermittent camper/paddler since my teens, but now that my kids are avid Boy Scouts,
I've caught the backpacking bug. I typically do 8-10 weekend hikes per year, and have spent time over
the past few years backpacking the Philmont Scout Ranch in New Mexico and canoeing the Atikaki wilderness of
Canada. I like to travel "in comfort", but I've shrunk to medium weight, and continue to work toward going
lighter and longer. With all of my investment into these ventures, I expect my wife and I will continue to trek
long after the kids are gone…

The T4MO Tilley Organic Airflo Hat is a wide-brimmed hat for hiking, boating, and really any other
outdoor activity imaginable. The hat is made of 98% organic cotton and 2% spandex, so it has a very
soft, cottony feel. The texture is somewhat of a contrast to my previous Tilley hat, which was made
out of their nylon fabric (Nylamtium), which has a more plastic-y feel to it. The fabric provides 98%
protection against UVA/UVB rays, but one of the hang tags still recommends using additional sun
The hat is made with a mesh area around the top of the hat of about 0.75 inch, which is designed to
allow air flow and cooling of the wearer's head. The hat also contains a small closed cell foam pad
under the crown, which enables the hat to float in the water.
The design of the hat includes two windcords which can be bunched inside the hat when it is calm out.
In moderate wind, the rear windcord can be wrapped around the back of my head to prevent the hat from
flying away. In more severe winds, the cords can be tucked under the chin for complete security, as shown being
modeled by my suitcase handle in the photo below.
two windcords are made from a single string, and both ends of the cord have sliding knots, which allow
adjustment of the total length of the windcord. The cords pass outside the hat and back in via a pair
of grommets located on each side of the crown, which can also be seen in the photo above.
Although some Tilley hats have a hook and loop tab for
securing sunglasses to the crown, this feature is not present on the T4MO. However, I could still slip
the temples of my sunglasses in the cord to allow carrying when I'm not wearing them.
There is 1 1/8 inch (29 mm) anti-sweat band on the inside of the hat which is made of a wicking
Another neat feature of the Tilley hat is a small pocket in the top of the crown. This pocket is closed with
a hook-and loop closure to keep things inside secure. Inside the pocket are 8 'brag-tags', which carry small stories on one side and information on how to find information
about Tilley hats. The tags come with the cheerful suggestion that they be given to folks inquiring
about the hat. They also indicate that "it is customary to provide the giver of Tilley Hat procurement
information with A WARM HUG, OR STAND HIM OR HER TO A DRINK." The tags sit in a small plastic bag
"useful for stowing a fishing license or a spare $10 bill or a 5-euro note". The Tilley warranty and
instructions are also written there, along with a space for the user to write his or her name. The photo
below shows the tags sticking out from the pocket.
INSTRUCTIONS AND WARRANTY
Tilley is very proud of the fact that the hat comes with a "Four-page owner's manual". The instructions
cover important topics and some history about the company. It is recommended in the manual to wash the
hat regularly, which can be done in a washing machine using warm or cool water. The hat can also be
washed "by hand, with a scrub brush, with soap, soap powder, liquid soap, or perhaps shampoo." The
hat should NOT be bleached. After washing, the hat can be smoothed and reshaped to make sure it
maintains its original shape. It can also be stretched over the knee if it shows any sign of shrinkage.
The hat comes with "insurance", which is a 2-year period during which any lost, stolen, or destroyed
hat will be replaced at 50% cost. Beyond this, any Tilley hat that wears out (as long as it has not
been bleached) will be replaced free except for shipping costs.
INITIAL IMPRESSIONS and EXPECTATIONS
I'm not sure what I was expecting from the T4MO hat, but it looks essentially EXACTLY the same as my
LTM6 Tilley Airflo hat. The main difference is that the material is quite different, with the T4MO
having a softer feel, consistent with the fact that it is made out of cotton. This is not a bad thing,
as I really like my other hat. Aside from the feel in my fingers, I could tell when I slipped the hat
on my head that the material was softer with more give.
Right now, I'm excited to get this hat out on the trail and see how it holds up after a couple of days
in the, rain, dirt, and (hopefully) sun.

Over the FR phase of testing, I wore the Tilley T4MO on a 2-day/2-night hike on the Symmes Creek Trail
in Rio Grande,Ohio. It was sunny and hot on that trip, with daytime temperatures around 88 F (31.1 C) in the
bright sun. The total distance on that trip was about 10 miles (16 km) with elevation gain <300 ft (<100 m).
I also wore the T4MO on a dayhike from Lake Poway up Mt. Woodson and back when I was visiting San Diego, California
on a business trip in mid-June. Mileage on that trip was about 7 mi (11.2 km) with a 2000 ft (610 m) elevation gain on the
way up, and vice versa on the way down. Temperatures peaked at 83 F (28.3 C) on that hike in the bright sunlight. I also wore the hat most days
during a 2-week stay at the Boy Scout National Jamboree at Fort AP Hill in Bowling Green, Virginia
during the end of July-early August. It was very sunny for most of the week, with a maximum temperature
of 106 F (41.1 C), although high temperatures most of the week were around 92 F (33.3 C). I typically walked 3-5 miles
(5-8 km) most days, although covered about 12 miles on one day.
My first trip with the T4MO was probably the most typical of my usual hiking style. I wore the hat the
whole time when I was on the trail. It got quite warm during the afternoon, but wearing the hat didn't
make me feel warm. In fact, the headband helped keep the sweat from dripping down my face. The trail
wound in and out of the trees, and I liked having the wide brim providing me shade for my head. Once I
finished hiking, I took the hat off to let my head breathe a little. It was warm overnight, and the hat
had dried by the morning.
In order to wear the hat on the Mt. Woodson hike, I had to bring it with me on my business trip. The hat
was unceremoniously packed in my carry-on bag and came out quite flat. However, a few quick shakes and
it was good to go, as shown in this photo taken near the summit of Mt. Woodson.
On the hike, it was warm when I started out, and the trail started uphill almost
immediately. It was warm enough to make me start sweating right away, and the sweat dripped down my face
for the first 30-60 minutes. Once I got underway, the sweatband seemed to function better. I did not
wear any suntan lotion on the trip, despite that there was almost no tree cover on the trail.
When I got back from the hike, I had a significant sunburn on my arms, but only just a little bit of redness
on my neck, which had faded by the next morning. I took this to mean that the hat provided sufficient
shade to protect my face, ears, and neck from the sun overhead. I hiked from about 10 am until about 3
pm, so I was really out during the heat of the day. It was also fairly windy up on top of Mt. Woodson.
Most of the time I did not use the windcords, but I did fasten the cord around my neck when hiking
through particularly windy parts of the trail. This turned out to be a good idea as the wind whipped the
hat off my head on 2 separate occasions. I would have had to chase the hat down the mountain if I had
not used the windcords. When I got back to the trailhead, I noticed some staining around the sweatband, shown below with the arrows.
However, when I washed the hat next, this went away.
On my trip with the Boy Scouts, it was brutally hot and humid for most of the trip. Whenever I was out in the sun, I wore the hat as cover. Again,
I did not wear any suntan lotion, and I had no problems with sunburn. I also had some sweat staining, but this again washed out easily.
My only concern about the hat is with the styrofoam piece in the crown of the hat. Somewhere during my travels, this piece got a fold in its middle,
giving the crown of the top of the hat an uneven appearance. I took the piece out of the hat and let it sit under a few books for 3-4 days
to re-flatten it. I put it back in the hat and this seems to have helped quite a lot. If it becomes a recurrent problem, I will probably
try to call customer service and see if they have any suggestions.
WEAR AND TEAR
The hat has been sat on, flatted in a suitcase, and generally been abused. However, a few shakes and it looks nearly as good as new. As noted above,
I have also washed it 4-5 times already with no ill effects.
So far, I have been quite happy with the Tilley T4MO hat. I still like the feel of the fabric, and the hat continues to function well and with style.
My only concern about the hat is that the brim is a bit "droopy", meaning that brim tends to curl down, particularly in front. Although I haven't really
noticed this myself when hiking, I can tell whenever I look at a photo taken while I'm wearing the hat. This can be seen best when photos are taken from the
side, as shown below.

October 12, 2010
During the course of the long-term report, I wore the Tilley on a 3-day/2-night trip on the
Wildcat Hollow trail in Glouster, Ohio. The trip covered just over 15 miles (25 km) in beautiful
weather, with a daytime high of 82 F (28 C) and an overnight low of 41 F (5 C).
I also wore
the hat to work on rainy days, of which there have been about 4 or 5 during the course of the
All told, I have worn the Tilley T4MO about 20 days under trail conditions, and another 10 days
of "in-town" use.
I've worn the Tilley quite a bit over the course of this test, and it is truly a great hiking
hat. I found the brim wide enough that I really didn't need any suntan lotion, despite the fact
that almost all of my trips have been in the bright sun (shocking, isn't it?). There have been
a few times during the test when I have felt my head getting warm, but that has really only
happened at temperatures over 90 F (32 C) with a fair amount of humidity.
The T4MO has a tendency to get darkened with sweat after a long day on the trail, but the
discoloration washes out easily. I have washed the Tilley 4 or 5 times during the course of
this test, and it continues to look fabulous. Another feature I really like about the hat is
its ability to bounce back from abuse. I can cram the hat into a backpack, a suitcase, or a
corner of the tent, and I know it will look its usual spiffy self when I shake it out and put
it on my head.
It hasn't rained when I've been on the trail yet, but I have worn it in the rain on multiple
occasions. The waxed cotton seems to get stiffer, and water rolls right off the brim. The hat
also seems to dry quickly, although I haven't been able to test this on the trail directly.
I have gotten multiple positive comments on the hat from my co-workers, who are wondering how
I can look so debonair in the rain!
The only concern I have about the hat is the fact that the knots in the wind cord have come
loose once or twice. This is really only a minor issue, as it has been no problem to retie the
simple knots and restore the wind cord to its original state.
All in all, the Tilley T4MO Organic Airflo Hat is currently my favorite hat to wear when
I am hiking. It is also my favorite hat to wear on any occasion when rain is expected, be
it on the trail or around the town. It is also my favorite hat to wear when I am traveling,
since I know it will keep its shape no matter how I treat it. In summary, this hat is really
Things I liked about the Tilley T4MO Hat
Things I disliked about the Tilley T4MO Hat:
- Wide brim keeps the sun off my head
- Washing is no problem
- Hat is practically indestructible
- Pocket in brim is useful to store small useful items for the trail
- Knots in windcord came out once or twice.
- Some bending in the front brim
This concludes my report on the Tilley T4MO Organic Airflo Hat. My thanks once again to
Tilley Endurables for providing this equipment for testing, and to BackpackGearTest.org
for allowing me to participate in the evaluation process.
