But... I don't know where you could get just the leg loops, plus they would have to come off a different harness (since the Tomcat only comes in one size?). The leg loops off a DMM Renegade or similar should be fine; you could try asking DMM directly but they may not have (or be willing to sell) spare leg loops, or you could try and get a second-hand harness and just use the leg loops (ideally something with a worn-out belay loop but OK tie-in points for example).
