Anyone have experiance with Weezle?

[LKunze]

I think you have to try both types and make your own decision based on that.  How warm one is wearing different undergarments varies from diver to diver.  Opinions are all over the place when it comes to comparing Thinsulate and Weezle undergarments.  I've heard and read opinions from users that have used both and some prefer the Weezle such as John and I've also heard of divers that preferred Thinsulate over the Weezle.  Without actually trying both in similar conditions you won't be able to accurately find out which one is better for you.  Also, DUI is not the only vendor that makes 400G thinsulate.  All of the high quality thinsulate material is made by 3M and there are other vendors that make undergarments from this material.  The DUI thinsulate is Grade B insulation or sometimes called "boot grade" which is very dense and does not compress as easily as other materials. Theoretically this means you'd need less gas in the suit or less "loft" in the garment to keep you warm.  On a side note I used to use 300G fleece with a 100G REI fleece top and bottom layered underneath that.  For me personally I was not as warm in that as I am in my 400G thinsulate garment however I had better mobility and was able to vent gas from my drysuit much more efficiently in the fleece.  I only wear the fleece garment now if I'm doing shallow dives in the peak of summer when the water is warmer.  Anything below 70F and I'll wear my Thinsulate.
