marinlite cantis
mmm....
never actually seen a genuine pair in the flesh..although should have'marin lite'printed on somewhere.i think these were an optional extra.i think they feature in the 93 catalogue on here,im gonna look now for reference but,
ive a feeling yours are some generic copies? ive got a pair very similar to your set and i dont find them particularly lightweight,nicely made though and should be durable.
