Really comfy, looks fairly trekkie, not enormously warm in really cold weather but very good for it's main purpose...which is:-
...... under a leather jacket keeps you just warm enough on the road whilst affording you the bliss of not getting all hot and steamed up when stopping for ten minutes to water the pony, check the tire pressures, kick the GPS or argue with a jobsworth etc.
For some reason women seem to think it's a high fashion garment and forever seem to want to 'borrow' it.
PS There is a design defect with the detachable sleeve attachments which have 'wandering' zips in the armpit area. Stitch 'em down if you are not overly beholden to the detachability requirement.
