I wanted to share this with you guys here given that I have been so impressed with this product.
Someone mentioned Polartec Powerdry in a post a few weeks ago pertaining to drysuit layering. This is what IR Thickskin is made from.
I had to give it a try and I am really glad that I did.
I have tried EVERYTHING as a base layer under my drysuit and have been pretty disappointed with most. After trying various rashguards, capilenes, polypo, etc. I finally settled on SmartWool and thought it was pretty good. It is pretty good actually, but it does not compare the the ThickSkin.
I have only used it a few times but I have been very impressed. It really does keep you dry. I sweat like a beast under a dry suit regardless of the temperature. I usually end up soaking my base layer, feeling soggy and getting chilled if I stop.
The ThickSkin has enough absorbancy to soak up all of my sweat without becoming saturated and to keep the moisture on the outside of the fabric. You never feel damp or chilled.
Also is not so warm that it causes you to overheat. It has been a bit warm at first when paddling in the high 30s but a bit of rolling and a bit of perspiration evens it out. Plus it is a pretty good insulative barrier between you and the cold water.
I paddled last night and got fairly sweaty. The temps were in the mid 30s when I quit. I took off the dry suit and just wore the Thickskin home and while I unloaded my boat and truck in the cold weather. I never felt chilled or damp, but the outside of the fabric was quite damp (left a big wet spot on my car seat). My skin was dry as can be.
It is also highly wind resistant. I acutally plan to use the bottoms for winter backpacking...as pants. Unlike other paddling layers they don't have a fly so they really are not long underwear...their a pair of tight fitting pants.
Very impressive product.
No I don't own stock in the company. Just trying to help out those looking for something better to use under their suit.
