Fits well and movement is good and there's little restriction at the extremities. If it were a shirt it would be a tailored fit as opposed to regular or a baggy fit. Less to catch on fences and scrub etc as it's close to the body. The C sizes are tighter than expected so if your a 34/36 go for the 36. It's single layer and very thin but held up well in a few hours of wind and rain. The base and mid layers stayed dry. It does not offer much insulation and outside of UK climates it's going to be lacking. A harsh UK winter is probably the ultimate limit of its capability. UK Spring, Summer and Autumn is where it excels and it folds well to for when you over layer and need to remove one. Best used with a merino wool baselayer and micro/thin fleece.
