The multifabs suit is not bad for comfort, the seals are pretty tight - but that is the way they have to be.
Contary to early advice do not get a front zip - the majority then have some sort of compromise at the neck seal. That means either the neck seal is uncomfortable at a minimum or worst it leaks - which pretty much invalidates the whole reason for wearing the suit!
