I bought the piper knit fabric silicone full seats a couple weeks ago. I actually find the fabric superior to the regular pipers I have. I did not find them to snag at all, between riding 3 horses, throwing hay, and all such other activities one participates in when at the barn for 7 hours 
The rise I was worried would be too high, but it falls just below my belly button. So very comfortable. I LOVE the silicone. Especially in paisley. The only things to consider really is that (at least in full seat, as my friend has the knee patch and did not report the same fit) you MIGHT want to size up one. I ordered my regular size and it still fit fine, but tighter than my regular pipers in the same size.
Also the belt loop won’t accommodate a wider belt (read regular C4), you’d need the skinny. I’m always open for excuses to buy more C4s, so this was actually a plus.
