Neckseal sizing

[Mark-B]

Has anyone any ideas about sizing a latex neck seal ( on a membrane suit if that makes a diff), I dont use mine unless I really really have to, as I dont like the seal as it feels too tight, bearing in mind that I wear shirts with a too big collar as I cant stand ties too tight, so it may be just me, I tried it on today and my Girlfriend said I went a bit red in the face, closed the dump and squatted down, no air escape at all from any seal or dump, Measured my neck and it is around 41cm and then measured the seal and its 13cm across unstretched 26cm in total, does a 15 cm difference sound excessive ?,

Any advice would be most appreciated.

Cheers

Cut it baggy then use a zip tie

Or gaffa tape, black of course.

Mark,

Once you start to get to the bigger end of the neck market it become a little more difficult to get a comfortable fit with a latex seal.

I personally find a neoprene seal much more comfortable and you don't get the 'recently garrotted' neck mark either.

You could give that try.

All the best

As a rule of thumb, cut your neck seal so that it is 20% smaller than your neck circumference (though I would advise that you do this cautiously). For you this means cutting it to a circumference of 32-33cm which is a fair bit bigger than you have at the moment.

Thanks for replies,


I did pick up something about the percentage of seal/neck size but could not find out the recomended %, as mine is around 37% smaller I would think it is too tight, will knock it down to 30% to start and then gradually go to around the 20% mark and hope I dont stuff it up.

Many Thanks for the tips, especially the zip ties, and gaffer tape cheers.

I bought my first dry suit and found the neck seal to have a tiny opening. It felt like my head was inflating! I trimmed off about 7mm around the edge and tried it on again and it felt much more comfortable. Now of course I am scared I trimmed too much and am scared to go in the water in it! The opening is still small compared to my neck size though. I think I need to risk it and try it in the pool before I take it in for a new seal.

I would definitely trim yours. Assuming the neck seal has the rings around it, its a good idea to not trim more than one of those at a time away. Do it in small stages, you can always remove more, but you can't put it back!
Obvious I know, but its amazing how many people make that mistake and a new neck seal would be a pointless expense!

Thanks,
Yes it does have lots of rings on it, and a bod at work has said same thing, so will trim it back a bit and try it, from advice given on here I should have quite a bit to cut off, but a little at a time until I am happy,

Thanks

Mark
