Going to try my biiig ATF fleece-lined Navy deck jacket over my Headwind cape A-1 for subzero cold plus wind chill. Probably nicely warm, but how lameass is it to wear your leather anywhere but on the outside? I wouldn't give it a second thought if it were a full-body suit, but a jacket is different somehow. Has anyone had overheating or perspiration issues doing this? Wouldn't try it with horse or goat, but the cape is thin enough, I feel I might get by.
