The name Astroglide actually has a very fitted back story. The creator of the product, Daniel Wray, is a former NASA aerospace chemist that worked with almost 300 different formulas in order to find the perfect concoction. The result of all of this research and development is a lube with extraordinary moisturising and lubricating properties that mimic naturally occurring body fluids to a near perfect match. Something that sets this aside from the rest is it's ability to keep its lubricating charm for hours with the need for top up or the aid of moisture.
