I do take mine with me most days... BUT now that it is getting hot... They wont travel with me as much. I do carry a water bottle with cool water in a cooler and some fruit. I use Grapes, they have a higher Wet content to me!
Make sure you get a lightweight pouch now that we are coming into summer! Here in Houston it has been HOT!
I actually just found some LIGHT Fleece and then for the outside I am going to try to use T-shirt material. We will see how that works out!
BUT anyway... Make sure you have water with you! Also... Freeze your grapes... They help keep you and the gliders cool!
