Fits slim, but fits well on me (medium) - Condor Outdoor O.D - Base II Zip Pullover

I ordered it because I really liked the fleece I had tried on before and this was a very close match. It makes for a great base layer in the winter. I use it under my goretex and other sweaters. You can use it under certain uniforms as well. The only thing I wished it had was the hand pouch/pocket like the FROG ones do.
