Price Paid: 89$
I have a C1-11 from about 2008 and it has worked great and lasted me until now (2011). It did start to split in a few places, where the knee material joined the leg split apart. Some of the seams on the inside came apart, but some wetsuit glue kept it going.
I use it for kitesurfing and it does well keeping me warm in and out of the water. I just got another one the Mundaka C1-11 from STP. for the price it can't be beat it seems to me.
