Through a patented material connection, these are the world's first silicone sleeves which can be assembled by the usual contact bondingprocess in all suit sizes, types, materials. So these boots combine the best material properties of the silicon with the flexibility of latex sealswithout damaging side mechanical component connections. 

They have a very high elongation at break and are dermatologically safe. The sealing on the skin area consists of a comfortable wall thickness to efficiently seal and to ensure maximum tightening and comfort. 

A really great problem solution, which we have been waiting for. 

Scope of delivery: 1 neck collar plus instructions 

On request we can provide, of course, the service performance of the assembly to separate calculation.
