well... you'll be surprised that many leather jackets in the
market are as heavy as well, if not, even heavier.
As for my case... during a hot afternoon, i will normally remove
the sleeves so that it'll be more cooling... then at night I'll put
them back in place before i ride out in the cold nights.
Personally, i haven't regret buying it myself. But i admit it's a
expensive investment though.
