I like switching collars depending on the time of year. During the summer I will use a lighter weight quick release collar so that if it gets wet it can dry quickly but I do have a quick release leather collar that I use.
It is one of the only leather collars that I have seen that is made with he quick release hardware and it is very high quality.
This company also make leashes and service dog equipment here's their link:

I also put my tags on a special clip so that it is easy to switch collars, since I rotate collars.
