I recently acquired one of the Ferrino Trekkers, and here's my report.
This coat/poncho has a more flowing. looser fit than the typical coat, but not as loos as a poncho. I have a S/M size, and am 67 inches (170 cm) tall. The hem comes just below my knee in front, about the same length as the poncho used previously. This is short enough to make me ponder the possible use of gaiters or rain pants. The sleeves are pleasantly long, with elasticized cuffs. The hood fits well, and does not assume you are wearing a helmet, as so many mountaineering jackets do these days. There are chest vents, but no pockets, slits-for-pocket-access, etc. The full-length zipper is well constructed, not too heavy nor too light. The extra fabric in the back fits easily over my 48L Osprey Exos pack, and there are three snaps arrayed across the back to fold the excess fabric out of the way if you are not wearing a pack. The coat seems well made, light but sturdy. The interior is lined with some sort of aluminized, shiny material that is most likely heat reflective; I wonder about that in warm weather. Otherwise, I am quite happy with this item.
