I've surfed Rip Curl wetsuits for about 6 years now. They fit my body perfectly (better than all other major brands) and use solid materials. I'm 165, 5'10" and wear medium. B/c this is a classic model, there is only ~20% elastomax used, albeit in arms where flexibility is most critical. No need to pay premium on spring suit to have 100% elastomax (pay premium only on full suits). New feature (finally!) includes key pocket outside left thigh which is big enough for car key. simple, almost too simple, but seriously, why did it take decades for this to be introduced?! Kept me toasty on North Shore!
