Choose the summer best strap for the Rolex Explorer II 16570

Looking to change things up a bit for the summer and need your help!

1. Supple and tanned vintage style Italian leather by Meccaniche Veneziane?

2. Black, vanilla scented deep sea dive rubber from Isofrane?

3. Olive drab heavyweight canvas drawn from old military bags dating as far back as WWII hand assembled by Red Rock Straps USA?

What do you think? Let me know in the comments below!
