I found this to be very helpful and just curious what other's
experiences have been. I have an O'Neil "powerstretch" top under a
0.5 mm titanium lined neoprene top ("hot top") and found this to be
incredibly warm.
Perusing the web, it seems like there's a fair amount of unknowns
about the physics of wetsuits, but I'm wondering if the fleece works
on a slim person like me (with long arms, fairly wide shoulders) by
filling in some of the gaps of the not-great-fitting neoprene.
Other tip I can offer is I also added the Aqua Sphere 0.5 mm "hood"
and for something that weighs almost nothing, it adds a lot of warmth
as well. (Again, may have to do with being an ectomorph, and normally
loosing a lot of heat out of my long neck.)

You'll likely find a few more folks familiar with this sort of thing on
the triathlon newsgroup.

Wet suits retain heat mostly by trapping a small layer of water under the
suit, which then warms up and acts as an insulating layer (that's why the
first 5 minutes feels colder, while the water layer is penetrating and
warming up). Adding a fleece may trap some extra water (they are designed to
trap air within them in dry use), and so may add to the insulating effect.
However having a saturated fleece under the wetsuit will add weight and
reduce ease of movement so you will swim slower and may be less flexible and
possibly less buoyant. I would not recommend it.
Adding a hood acts like a wet suit on any other part of the body, it's just
that the head and neck have very little fat covering and so feel the cold a
lot, especially at the start as they are cooling down before the peripheral
blood supply shuts down, so covering them with a hat or hood is a good way
of preserving heat and as the skin area of the head and neck is surprisingly
large, it helps overall thermal saving. |

The thing about this explanation is that a thicker wetsuit is much
warmer than a thinner one. If the trapped water was the main source
of insulation, you wouldn't expect that to be the case.
Also, in terms of fleece, as I said, the skin-tight "powerstretch"
fleece that is now used, doesn't retain very much water at all (quite
thin). And consistent with the trapped water hypothesis, if you're
neoprene doesn't fit that well, I'd expect the fleece would aid in
slowing water movement in the insulated barrier.
Another benefit of the fleece is that it keeps you warm when you get
out of the water, much more effectively than neoprene.

Quote: This is a common misconception. They warm by insulation.
Insulation 'warms' nothing (only a heat source 'warms' something) , it just
retains the heat, the source of which is the body itself.
Obviously a wetsuit provides some insulation and the thicker the better, but
the warming of the water next to the body is a very significant factor, and
one included in the design. At least that's what the manufacturers say, but
if you know better maybe you'd better tell them - see
http://www.explainthatstuff.com/howwetsuitswork.html
I would still not recommend the OP to wear a fleece under a wetsuit, it
could actually become so unwieldy as to be dangerous. If he is cold, get a
thicker wetsuit. then if he is still cold, get out of the water and stay
out.

Did you read the website I pointed you to?
A fleece could only work by trapping air (which would add to bulk and make
it too buoyant) or more water (which would make it less buoyant, heavier and
less flexible). If it is such a good idea, why don't the manufacturers line
wetsuits with fleece?
But if you want to waste money and drown yourself, be my guest.

Sounds like that woolly trout from England's Lake District.
Tried a wetsuit that fits? |
