The summer heat can finally be beat with Macna's new Dry Cooling Vest! Designed to keep you cool AND dry during hot weather or if you live in a hot climate, the process is simple - fill the vest with 500ml of tap water, wear it over a synthetic base layer, and prepare to be like Fonzie - COOL!

To size yourself for the vest:

  • Order one size above your normal t-shirt size

A bit of an air cushion between the body and the vest allows wind to pass through and aids in the evaporative cooling effect.

Does it work in humidity?

Testing has been done and the answer is yes, it does work in humid conditions, though at 80% or higher humidity the cooling effect does start to diminish. This is most apparent when you are standing still. While moving on a motorcycle air is pushed through the cooling vest and aids in the evaporation which enhances evaporation. This offsets the diminished performance caused when humidity levels are high by effectively turbo charging it.

Other Features:

  • Anti Microbial
  • Machine Washable - Place in a mesh bag, use a gentle cycle and a mild soap. Hang to dry.

Special Note: Overfilling the vest diminishes its ability to evaporate properly and renders the vest inoperable.

Review by Omar7375
I got this because the wet vests just don't work in Oman due to the 90+ humidity and well above 100f temperatures. The Quality is great and fits well (one size bigger). However, it didn't make difference in my weather like the dry vests. Also it's a pain trying to pour te water in and ensuring it spreads around. Would have been better with 3 inlets for the 2 front sides and rear area. (Posted on 6/3/2016)

I bought this vest almost 2 years ago and it has proven indispensable in HOT Texas, commuting on a Harley in stop and go traffic (often 45 minutes to an hour). It works. I do wear a partially mesh mostly textile jacket. I love that it does not soak my shirt because I really don't want to have to change clothes when I get to where I'm going.

Once you get the hang of the water amount and what that feels/looks like and how to easily distribute the water, it really is very quick to get it ready to go. I personally judge the water amount by distributing the water and then holding the vest upright to drain the water to the bottom of the vest and look as the "sag" on all sides. Sometimes I just move all the water to one front panel and judge that way - might be easier for you. Of course, you need know what that "sag" looks like when you have measured the water into a dry vest. You do not have to be exact but you DO have to be close.

It is pricy but it is holding up marvelously and that's saying something in Texas. For example we had 90's here in November and early December this year, so it does get used a lot. (Posted on 4/5/2016)

Definitely helps keep you cool, but you need to have lots of air flow. Works best with very thin shirt or microfiber shirt. If you don't let it dry out completely, it can be difficult to know how much water to add to recharge. (Posted on 2/22/2016)
Review by Ben
I ride in the Arizona desert and it can get quite hot when you stop in traffic. This vest not only keeps you cool while moving, the water inside keeps you cool when stopped also. It's easy to fill and you don't get wet. (Posted on 9/25/2015)
Review by Superfunkomatic
The first time I used the vest was last week on a trip from north Florida to the Texas hill country. It kept me cool even when the temperature got over 100. My clothes didn't get wet and the initial charge of water lasted all day. It is easy to fill; l just poured in some water and laid it flat for a while to let it even out.
A couple of people asked if it was a bullit-proof vest; might be a good feature to add :-) (Posted on 9/18/2015)

The Macna cooling vest worked well. However, in TX more is needed. The temps here are in the upper 90s. Less than those temps, it would be very effective and recommended. (Posted on 9/3/2015)

Today weather was 101 f and the humidity was 31
Yesterday weather was 120 f and humidity was 43
Review by DMcR52
I bought for a motorcycle trip in hot Summer Texas heat. Not a scientist, but believe it greatly improved the experience. I think it dropped my core temperature at least 10(ish) degrees. Fit was good. (Posted on 7/17/2015)
Review by JohnVStrom
I got my Dry Cooling vest just in time for a summer ride into the interior of BC. At highway speeds, or even if you are rolling without stops in the city, you notice a distinct cooling effect. In stop and go traffic, or sitting at a red light, you'll still feel the heat creeping up, but not as fast as without the vest. The one thing that seems to reduce the perceived cooling is high humidity When you are already damp from the atmosphere, evaporation doesn't feel like it's helping. I have to note that it is hard to prove a negative - in other words, would I have been melting faster without the vest? I'm not going to volunteer for that control test!
Overall, I think the Macna Dry Cooling Vest made a number of tough riding more bearable, but I was still happy to get inside and out of the sun at the end of the day. (Posted on 7/4/2015)
Review by ChrisE
Bought this hoping it would provide some much needed cooling. I've worn it a few times and cannot feel any benefit other than the extra coverage, provided by this, makes those areas of my body hotter. (Posted on 9/1/2014)
Review by Hal
I live in a very hot climate near Las Vegas NV. Put the half liter of water in it and it lasted an hour and a half. It is hard to feel the cooling effects but I know it does cool you slightly. You do stay dry but the ones you soak seem to work better. (Posted on 8/14/2014)
Review by hmwave
Been using this jacket in 85F weather under a perforated leather jacket.
Very first use filled it with 500ml as instructed. It noticeably kept me cooler on a half hour ride to work.
I've since used it daily for around two weeks and some days it cools well and some days it seems to have litle effect.

The product works well when it works but there are a few problems:
1. It's very hard to know how much water is needed to refill the jacket after it's been used a few days. The instructions warn against overfilling, but it's hard to know how much is needed to avoid overfill. The jacket really needs some form of fill level indicator. I'm having a hard time keeping it filled just right which is frustrating.
2. The fill port is on one side only so getting the water to the other side is a time consuming process. The jacket has to be turned sideways, upside down, and rotated to spread the water fill evenly across the vest.
3. The jacket has airflow holes across the front and back but they are small so don't flow much air. After a 30min ride to work the front and back of my undershirt is always partially soaked with sweat, even when the jacket feels like it's cooling.
4. I find the rear bottom of the jacket curls upward at the outside corners which can be a little uncomfortable on longer rides.

I expected better for a $150 cooling jacket. Until the problems are eliminated I would not buy another. (Posted on 8/13/2014)

We bought these during a month long cross country trip. Hitting the 115° desert with them was like having air conditioning.
Thanks to that Danish couple we met who recommended them! (Posted on 8/5/2014)

Product is way too small.. I bought it two sizes larger then usual and it still did not fit (Posted on 7/18/2014)
Review by RobertV
Purchased the vests shortly before our trip from LA to Glacier Park via AZ, UT, CO, WY. First days were real hot. Temps up in the nineties and these vests turned out to be our life savers. They really work well. Just 2 cups of water and make sure the water is spread well, and you are much cooler as a result. We wore them over our tech t-shirts under a mash jacket. Super investment! Much better than the ones you need to soak and re-soak after an hour. These new designs work for days. Just refill them a bit when you notice there is less water in them. (Posted on 7/15/2014)

Brought this on my ride to the southwest. Tried it out in northeast Texas. Doesn't work. Going back. (Posted on 7/10/2014)
Review by kevink
Last week rode to Grand Canyon, Monument Valley, Brice, and Zion national parks with vest on in temperatures that ranged from 100-117 degrees. The vest felt a little cool in some areas but most of the time at the end of the day felt like I was wearing a piece of plastic....not sure anymore how much water to put in it but followed the commercial and seemed to little...I put in more than half a liter and seemed to work better. By the end of the trip, felt better with it off. Not sure I would recommend unless I am completely using it wrong...not even sure it works in temps that high. (Posted on 7/10/2014)
Review by Comanche
I bought a Macna in April and had my first chance to test and evaluate it on May 12 during a 475 mile ride from McAllen, TX, to San Antonio and back. I had a second chance during an 800 mile round trip from McAllen to Houston on June 7-8.

First - sizing. Some people have expressed problems with sizing when ordering. The Twisted Throttle web site tells you to order your t-shirt size. Two friends did so and the vest was way too small for them. I emailed Kevin, the spokesperson on the video from Twisted Throttle, gave him my t-shirt size as "large", and he advised me to get a XXL-3XL. It fit perfectly. That would be my first recommendation to TT - change the sizing advice on the site.

The conditions during the May 12 ride weren't the best to really evaluate the vest. Here in deep south Texas, it is a tropical and very humid environment and I wanted to see if the Macna would perform in that weather. When I left the house at 7am, the temp was 78 degrees with a dew point of 73. In other words, very sticky. But, most of the day was spent riding under cloud cover and the temps never got to typical south Texas levels. It was in the mid-80s in San Antonio and the highest temp I rode through was only 90. But - it was humid the entire ride. When I got home at 4:30 pm, the temp was 87 with a dew point of 75.

However, I took another ride on June 7-8 - an 800 mile round trip to Houston, and this time, the weather was more typical. When I checked into my motel room in Houston, the temperature was 95 with a dew point of 73. Both legs of the trip were in high heat and humidity, with the highest being 98 in the small town of Falfurrias, Texas.

Next caveat - I wear mesh. My Motoport Kevlar mesh jacket is the only riding jacket I own. Many people recommend riding with a textile jacket and keeping only the arm vents open. That all makes sense to me as that keeps the cool air inside the jacket rather than escaping through the mesh. (Think about keeping the windows open when riding in an air-conditioned car). But the budget will have to wait until next year before buying another jacket.

I wore the vest over my synthetic base layer during both rides.

I didn't expect the vest to perform as well in high humidity as it would in the desert, but I also wanted to know if it would function at all.

Bottom line - it does work in high humidity. And - there is no sense off moisture on the skin. In other words, it’s not clammy.

But keep in mind, I don't mean you will be chilled, but the vest does work. There is a difference between being comfortable and being safe. The Macna vest will not replicate being in a cage with air conditioning, but it will help keep you safe by lowering your core temperature.

During the first ride, as I was going home, the vest didn't feel very cool. I stopped and took the vest off for a while and I began to feel hotter. After another hour (or so), I stopped again, recharged the vest with more water, and immediately felt cooler. On the second trip, I didn't remove the vest, but when I stopped to refuel or drink some water, I noticed the vest was cool to the touch.

A thought for Macna:

The instructions are quite specific that the wearer should not overfill the jacket - but it is very difficult to tell when the vest is empty. Perhaps some sort of "gauge" that would measure the moisture in the vest would be an objective way to indicate when it is time for another refill. Perhaps just a strip of material seen through a window. I refilled the vest once during the first ride, but I was not sure if it was indeed empty. I did not refill it during the six hour return leg of the second ride because I could still feel some liquid in the vest. I assume the evaporation process is just slower in the high humidity.

Now that I've had a chance to test the vest under humid conditions, I assume it will work better in dryer conditions. When used in combination with synthetic underwear designed for riding, and staying hydrated, the Macna is a keeper. (Posted on 7/7/2014)

This is the best cooling vest I have ever used.

A great purchase. (Posted on 8/15/2013)
