The Glyde Ultra condom is a standard size condom but made from completely vegan products. Glyde condoms are truly vegan and have been certified by the Vegan Society every year since 2006. Whereas most latex condoms contain a milk protein called cassein, Glyde however uses a thistle extract which does exactly the same as casein. As with all condoms Glyde are made of natural rubber latex which is a plant based substance harvested from rubber trees, but what makes them truly vegan is the additonal extra used in the process. Although it may make the product slightly more expensive, it does keep it 100% vegan. This 100% plant based product can even be composted and all boxes are made with 100% recycled cardboard and vegetable inks.
