Climate protection in bags

[PrinceYonex]

Does the climate protection foil in racquet bags actually keep the temperature down? Has anyone ever actually checked the temperature in compartments with and without the insulating materials?

the "foil" lining is indeed cool, but is a myth of being "climate controlled." Plus if you keep your bag indoors it doesn't really matter if it's outside for a few hours each day.

No. I like to think of insulated bags as temperature shock protection only.

For example, it's 70 inside the house and 90 outside, and 140 inside your car. You walk outside and throw the bag in the car and turn on the air conditioning. Eventually it comes down to 80 in the car as you drive to the courts. When you get there you pop the rackets out of the bag and play. The insulation prevents your racket from going 70-90-140-80-90. Instead, it's more like 70-80-90.

Or, in winter, if you walk out of the 70 degree house and its 32 outside and the club is 65 inside, your racket will be shielded from the cold air outside between the house and the car and the car and the club.

But if you left your bag in extreme hot or cold for long enough, it'll definitely be affected inside and out.

Now, just how much damage are you actually doing to the racket allowing it to get up to 140+ in a car is debatable.

IMO it does work. And even a small difference can be significant.

This is really helpful. Is the implication then that if the bag is sitting in the sun on the court for an hour it will, in some amount of time, get up to the outside temperature or even, eventually, higher? So that the main thing is that it slows the rate of temperature increase, as compared to a non-foil compartment?

Yes, eventually the bag will equalize in temp with its surroundings. How long it takes would be an interesting thing to find out.

You could perform an experiment with a video camera and an indoor/outdoor thermometer. Put the outdoor probe inside the bag and zip it up, then bring the whole thing outside and place it in the car. Video record the display and then you can see how long it takes for the heat in the car to penetrate the bag. You could also put the indoor side inside an uninsulated section of the bag to see if there's a difference between the insulated and uninsulated sections, and how much.
