Difference between dry suit and immersion suit? . .. .Don't know but an immersion suit usually has the following features:. .. .Diagonal zip to allow ease of entry (yeah right). .. .Tight rubber gaiters at neck and wrists. .. .Feet which (should) fit into ordinary footwear. .. .Suit designed to be worn over normal clothing. .. .Whistle and light for attracting the attention of sailors (???). .. .No bouyancy aids and all air must be expelled from the suit before finally zipping up. Otherwise your legs end up on the surface with your head well below it!. .. .A pal of mine who is 6ft tall and weighs around 25 stone is at the checkin in North Deans to fly offshore for a day visit. Goes to counter where they hand out the suits. Issueing chap doesn't look up just ticks name off list and asks the standard question "Large?". My friend replies "Don't be f***ing funny pal". Chap looks up and proceeds to nearly wet himself cos he's laughing so much. We thought they were going to have to zip 2 suits together for my pal. <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" />
