i can't speak to the tucano second skin, but i have a powersleevz for my 12" pb. i had wanted one so i could slide it into my backpack and not worry about it getting scratched. it does not provide any padding - if that's what you're looking for, i'd suggest a full-on sleeve case instead (i have an acme sleeve - it works great). anyway, i do like the powersleevz and think it was worth the $20+ USD (though i got it as a christmas present, so i guess i can't really say that!😀 ).
