This is by far the best fleece I've ever owned. The 100 weight polartec fleece is great for layering. I plant to use this fleece as a midlayer when the temps dip below freezing. Currently I use it for an "only layer" while lounging around. The side panels on this fleece do a great job of moisture control with a waffle weave wicking inner layer. The front panel of the fleece has a soft comfortable mesh on the inside to improve wind resistance and breatheability. I purchased this fleece for it's technical qualities (not for the style) but it looks great! Immediately after taking it out of the box, I had other Marines asking me where to buy one. I can't wait to hit the trails with it this winter.
