From the EB website:
Pino Palladino Signature Smoothie Flats Bass Strings are engineered for a smooth, effortless playing experience. Precision-polished for an ultra-smooth feel, these premium flatwound strings glide easily under your fingers. Wound with a cobalt alloy ribbon, they deliver a deep, rich tone that perfectly blends vintage warmth with modern flexibility.
I think means that they are the same wrap construction as the normal Cobalts, as the description of these reads:
Featuring a SuperBright Cobalt ribbon wrap, Cobalt underwraps and optimal hex-core to wrap ratio,
Although no mention of the under wrap on the PP set.
