I have the old SoftTouch Frogskins with the unobtainium-type coating on the frame and stems. In 2016 I picked up this pair. Same non-slip coating. What other frogs or lifestyle frames have the same coating…I love ‘em!

Interesting. There have been so many collections over the years, it's hard to determine what had which features. All to often, it was just a color theme.
