[Practical Impressions] The electric “new Liquid Wind” is a lifesaver in the middle of summer!

A brief introduction to "Liquid Wind."This cooling item directly wets the underwear from a bottle filled with cooling water at the waist through the vest's water supply tube and is rapidly cooled by the bike's running wind.It is said to be a "wearable radiator" that is cooled by cooling water and running air.

Have you ever experienced the "Refreshing Feeling" of riding a motorcycle with a cooling spray on your body? ... That's right! This is a dream item that lets you experience that cool, comfortable feeling all the time!

What has changed for the 2024 model?

In the conventional model, you had to "manually" squeeze the lever to dispense water like a spray bottle, and it was inconvenient because you could only use Taichi's designated underwear.

The new Liquid Wind for 2024 "automatically" dispenses special cooling water from a bottle attached to the waist, and you can wet your underwear directly through a tube inside the vest. Another major benefit is that the tube is now installed in the vest, so you can use your favorite underwear.

What items do you need?

What items are needed when using Liquid Window?
(1) With tubes that spray coolant from the front and back of the neck. RSU502 Liquid Wind Pumping Cool Vest"
(2) Electrically Powered "Electric RSP510 Liquid Wind Cooling Bottle Kit"
(3) Used for cooling water "RSP501 Gatsby Liquid Window Water"

How to use

1] Fill the bottle kit with special coolant.

Remove the double vacuum-constructed cooling bottle and fill it with the special cooling water.

This special cooling water was developed in collaboration with Mandom and contains highly refreshing ingredients that provide a long-lasting cool feeling. It also contains deodorizing ingredients, is fragrance-free, and does not leave a sticky feeling, making it comfortable to use.
In addition, by using the newly released optional cooling pack for the RSP511 Liquid Wind Cooler Bottle, the temperature of the cooling water can be kept cold for a long period of time.

[2] Wear a vest.

Wear the vest over the underwear of your choice. (A white T-shirt is worn for clarity when photographed.)

The vest has a simple design with a water supply tube inside and a pocket on the right side. The zipper on the vest is offset slightly to the left of the center so that it does not overlap with the zipper on the outerwear and become uncomfortable against the skin.
I am 177cm tall, weigh 70kg, and have a normal build, and the size L was just right for me.

[3] Attach the bottle to your waist and connect the water supply tube of the vest to the bottle.

Attach the bottle to your waist. The bottle is attached to your waist with the included belt and can be attached and detached with one touch, so it can be easily removed when you get off the motorcycle.

Then, connect the water supply tube hanging from the vest to the bottle. The tube can be connected simply by inserting it into the bottle kit, and when disconnecting it, just press the yellow button.

[4]  Wear a mesh jacket.

Then, wear your mesh jacket.

In order to maximize the cooling effect by taking in the wind while riding, be sure to wear a mesh jacket on the outside. This time, I wore the IXON mesh jacket BURNING AIR A.

[5] Turn on the power supply.

All that remains is to press and hold the power button for 3 seconds to turn on the power.

The power button is designed so that you can operate it without dropping your eyes, and the right amount of cooling water automatically seeps out from the tube around the neck.
There is an automatic mode that automatically dispenses 5ml of water every 5 minutes, and a manual mode that allows you to dispense water at any time. The built-in rechargeable battery has a continuous operating time of about 200 hours, so you can use it for multiple tours on a single charge. By the way, charging is done via USB-C.

My impressions after using it

I turned it on and rode my motorcycle in automatic mode. At first, it takes a few minutes for the coolant to come out because the tube is not filled with coolant. When I felt the first water flow, I felt a strange sensation, but when I was exposed to the wind while riding my motorcycle, the coolness felt comfortable.

The longer I rode, the more the coolant seeped into the inner part and the cooler area spread, making it very comfortable. The special coolant is strangely not sticky and is comfortable to use. The coolant comes in a 300ml bottle, so it can be used continuously for 300 minutes by simple calculation.

I rode for several hours in an environment exceeding 35 degrees, but when I was riding at 60km/h on a regular road, I felt cooler than I would have imagined for an outside temperature of 35 degrees, and enjoyed such a comfortable ride that I didn't want to ride without Liquid Wind. According to Taichi's test data, in an environment with an indoor temperature of 35 degrees Celsius and a wind speed of 6m (equivalent to 20km/h), the surface temperature of the underwear dropped by 5.2 degrees Celsius, but I felt even cooler than that, and sometimes even felt "cold."

In addition, wearing the Taichi-recommended "RSU329 Cool Ride Basic Undershirt" will definitely make you even more comfortable. (Don't forget to stay hydrated!)

A must-have item for comfortable summer touring!

The new Liquid Window is completed with only an electric bottle and vest, making it easier to use and remove for much greater convenience.In the past, only Taichi-designated innerwear could be used, and there was some hesitation about using it for short tours, but the new model can be easily put on and taken off, so the number of times it can be used is sure to increase dramatically! It is a very nice point to be able to put on and take off without hesitation, even when eating during touring!(Since the shirt is soaked with coolant, the "Isn't this guy sweating too much?" ("He's sweating too much, isn't he?" look may need to be addressed.)

The mesh jacket alone was enough to keep me cool, but the Liquid Window made me feel even more comfortable and greatly reduced my fatigue from the heat. It can be used with mesh jackets other than Taichi's, so if you don't have a mesh jacket yet, this may be a good opportunity to consider making a "mesh jacket debut".You will no longer think of riding a motorcycle in short sleeves or dressed like a baseball boy.

Liquid Wind reduces stress caused by heat, and is highly recommended for riders who do a lot of long trips touring or riding in hot weather! Why not give Liquid Wind a try this summer?
