no, synthetic is real quiet and very light, also the synthetic wont absorb a lot of water when it's raining, I've stood up after sitting in heavy rain for 30 minutes and just shake off most of the water. the burlap model is a different story though, burlap looks shaggier, but it will suck up water like a dish sponge.
and like what one of the other guys have said, rancho safari is #1 in quality. I've had my long coat for about 5 years now and it looks better than when i first got it cause it's worn in.
