Black Rubberised Leather (Togo) Signature Strap

Togo is super!

Togo strap looks and feels amazing. Not a hundred percent sure about the sizing and the clasp, so I will order a second bigger size (M) with a different clasp and have one of the two as backup.

What is the material? Is it Leather? or Rubber?

I find this strap excellent and it fits my Navitimer perfectly. In HK, the weather is humid and hot in summer time and using leather strap is a nightmare. I am going to use it in summer. I am wondering whether it is leather or rubber, is it ok to use it in summer HK, or Singapore?
