I am looking at the Mammut Kaula as my next to base layer. I am a rather sweaty guy and find that by simply wearing another synthetic or wool layer over my base layer I simply sweat both out in a under an hour.
The garment is made of:
93% Dryzone (Nylon)
7% Elasthan

What is your option on the garment?
