Cool. I will read it at BN.

I have an idiot measure of how long it takes;

50 4 minutes
40 2 minutes
30 1 minute

With drysuit and no insulation, double those numbers
every layer of insulation and being dry, double again.

My dry suit is a hybrid between tuiliq and dry suit. So, your head does 
not get wet.

I in fact made a bib with socks. I call it HB (high bib) since it comes 
all the way to my arm pit and to my neck. My tuiliq is a regular tuiliq 
with double head wrappers; thin neoprene and goretex overlay (yes, 
double wraps).

We went a 14 miler last week to Howard beach and it kept me toasty and 
dry. I did not have the hood yet then. US Navy makes great hard shell 
goretex or Gtex makes it and sells to USN.

I am done with the hood and it is quite tight. I will put another test 
over the weekend.

I am fielding out water proof zippers. Most drysuit has high pressure 
water proof zippers which are overkills for kayaking. I don't intend to 
go any deeper than few feet.

I want zippers that keep me dry in quick immersion during rolls or quick 
immersion.  I will end up zipping the bib to the tuiliq. :-)

I look like an exotic bird in US Navy fatigue goretex fabric. I was 
scaring the locals of the Howard beach.

Preferably, zippers will allow me pee easily.

By the 6th of January when some of Sebagoans going swimming pool, I may 
have the full tuiliq drysuit ready for full immersion.
