I juat picked up a nice spring jacket in tencel, I have another but it is a very light ivory color and I wanted something a bit darker (this one is dark tan). The salesman told tencel is made from wood and I did a bit of research on it and it sure seems like he is right. I had thought that it did not breath well but maybe that was must my belief that it was a poly like material. Things I like about my first one are the fact that it travels well, can be washed in the machine should it get dirty and holds it's shape. This may sound silly but being a natural fiber makes me feel a lot better about this material.
