I looking to get bicycle saddle cover what has been shaped as the saddle shape on the bicycle.  I'm seeking silicone or rubber solution because them materials are waterproof and durable enough to be used every day. And they are flexible / strechable enough to fit it on the saddle and to be taken off also.  I'm looking for the balance between the durability and the flexibility. So the cover need to be about 1,50 - 2.00 mm thick (depends of the quality of the material).  It shaped like the b?cycle saddle and it needs to have a little bit of reinforced edge what goes under the edge of saddle, so when the product is fitted on the saddle it wont pop off. Unless the owner will remove it.  I would like to get them products in 3 different sizes and many different colors.  I can mail the exact dimensions and measurements when required!
