Frequently Asked Questions
the MaxChillTM Sports Bottle?
The MaxChillTM Sports Bottle is a top
quality, 24 oz. bottle fitted with a sponge like, super absorbent shell.
Just get the shell wet and it has the amazing ability to cool your drink
as much as 30° below the temperature of the surrounding air.
The exterior shell was especially designed to absorb enough water to provide
several hours of cooling.
How Does the MaxChillTM Sports Bottle
The MaxChillTM Sports Bottle chills
your drink by evaporative cooling. What is evaporative cooling?
If you've ever gotten out of a swimming pool when the wind is blowing,
you have experienced evaporative cooling. Centuries ago man figured
out that if the outside of a container could be kept moist, the inside
of the container could be kept cool. Water bags and clay wine carafes
are examples of this technology. Unfortunately for the modern cyclist
neither of these are suitable for the rigors of bicycle travel. Hence
the invention of the MaxChillTM Sports
long will MaxChill work?
Actual road tests have shown that MaxChill will give you a
cool drink for 1 1/2 to 2 hours.
the MaxChill shell have to feel wet for the cooling power to work?
No, as long as the foam inside the shell is wet the cooling
power will work. The fabric layer outside the shell may actually
feel dry to the touch after about 20 to 30 minutes. However, as long
as you thoroughly saturate the shell before use, the foam inside the shell
should absorb enough water to to keep your drink cool for 1 1/2 to 2 hours
(that's the real test).
the wet shell be a dust magnet?
No, we have tested MaxChill on all sorts of dusty and
dry mountain bike trails and have never had a problem with dust sticking
to the shell. The reason is that the fabric layer outside of the
shell tends to dry out in 20 to 30 minutes. The foam inside the shell,
however, will stay wet for 1 1/2 to 2 hours giving you a refreshing, cool
drink for that amount of time.
I want to
know more about evaporative cooling.
Evaporative cooling is possible because of the large amount of energy
that is required to turn water into vapor. This energy, called the
latent heat of vaporization, will be taken from whatever the water is in
contact with when it evaporates. In the case of the MaxChill bottle
the water is in contact with the foam as it evaporates and thus as heat
is taken from the foam its temperature will drop. The following websites
provide additional information on evaporative cooling.
How Do I Use the MaxChillTM Sports Bottle?
Just fill the MaxChillTM Sports Bottle
with your favorite beverage and saturate the shell by gently squeezing
it under water. Then stick it in your bottle cage and go. As
you ride, the water in the shell will slowly evaporate thus chilling the
liquid inside the bottle.
work where I live?
The MaxChillTM Sports Bottle
will always keep your drink cooler than a standard plastic bottle but it
works best when the relative humidity is below 70%. The good news
is that as the temperature rises humidity decreases. In fact, for
every 20oF rise in temperature the relative
humidity is cut in half. So if at 6 AM in the morning the temperature
of the air was 70oF and the relative humidity
was 100% and the temperature rose to 90oF
by noon, the relative humidity would be 50%. So, no matter where
you live, as the temperature increases MaxChill's cooling power also increases.
is the MaxChillTM shell?
The MaxChillTM shell has a
colorful top quality nylon laminant that is made of the same athletic
grade fabric that is used for football jerseys. We use topicality
materials because we know you demand it.
Can I freeze
the MaxChillTM before an activity?
Yes, you can freeze the MaxChill before an activity but you
probably don't have to. For most activities evaporation of the water
in the shell should keep your beverage cool so you don't have to remember
to freeze anything. This is because using evaporative cooling is
750% more effective than melting ice (i.e., It takes 2500 Joules of energy
to evaporate 1 gram of water but only 333 Joules to melt 1 gram of ice).
Still, there are those activities which require Maximum Power Cooling
(e.g., a several hour cycling ride in the Arizona desert). When you
need Maximum Power Cooling just add ice or freeze water in the bottle
before the activity. This maximizes the time MaxChill can keep your
drink cool because you take advantage of the latent
heat of fusion and the latent
heat of vaporization.
Can I Use
the MaxChillTM Sports Bottle in
Sure, just remember not to saturate the shell if you're worried about
your water freezing. When the shell is dry it acts as an excellent
if I have a camelbak?
Camelbak's are great for carrying large amounts of water on
long rides but are not well suited for sports drinks. They are difficult
to fill and even more difficult to clean (Click here
to see what could be growing in your camelbak if it isn't properly cleaned).
The MaxChillTM Sports Bottle, on the other
hand, has a wide mouth top for easy filling and cleaning. In addition,
you don't need to add ice with the MaxChillTM
sports bottle so your sports drink will never get "watered down".
I clean my MaxChillTM?
MaxChillTM can be easily cleaned
with soap and water. You can also put MaxChill in the dishwasher,
shell and all. Just put it on the top rack away from the drying element.
The non-foaming nature of dishwasher soap allows it to penetrate the shell
for a thorough cleaning. You can also take the MaxChillTM
shell off and throw it in the washing machine. If you do, remember
that it is easier to take the shell on and off when it is wet.
