Just in today. Thought I would start a quick review. I ordered an XL and it fits a little big. It is kind of boxy cut like a First Lite Halstead fleece. For reference I am 6 FT 3 and 220 lbs 46-47 in chest. In comparison it fits larger than the Cronos Fleece in the same size and not as athletically cut. Kind of wish I went a large especially since it is a base layer but we will see. Arm length is plenty long. The material is like the Kryptek Hyperion shirt but a little thicker. The sleeve pocket is adequate i can fit three fingers in it. It has no thumb loops and the 1/2 zip is a little shorter than half. The altitude pattern looks slightly darker than the Tora pants.I was only able to try it on for a few minutes. The Tag states the material is 91% poly and 9% wool interlock fabric. It feels like it will breathe well. I plan to go for a run in it tonight to see how it feels. I am then going to soak it and see how long it takes to dry. It was $89.99.
