I'm looking to get some different opinions and advice on dry suit neck seals. When I first bought my dry suit it had a neoprene neck seal. Regardless of what I've done I'd get a leak in the neck seal. I would turn the excess inward and outward and I still would feel the water seep down my back whenever I get in the water. I sent my dry suit in for regular maintenance and to have a latex seal installed. Well it seems to be leaking worse and I end up with my boots with water. Fortunately I don't get very cold or hypothermia but it is becoming concerning. My dive guide this weekend told me that the neck seals should be very tight to the point its uncomfortable. I have a 18.5in neck and that's the measurement I gave to BARE. The advice I've been getting from some divers at my shop is to go down in neck size to possibly 17in. Looking for opinions before I spend the money to ship my drysuit back out to get the neck seal replaced. Thanks in advance, oh and my dry suit is leak proof, i leak checked it prior to sending it out and so did BARE when i had initially sent it in. So it's verified to be the neck seal.
