[quote=“Kevin Granade, post:11, topic:3337”][quote=“An0n3, post:7, topic:3337”]The difference between a trenchcoat and a robe or dress (I assume, I don’t have experience wearing dresses) is that your legs are still free to move without any restraint.
Trenchcoats are split in the back up to the waist and don’t button all the way down in the front to allow your legs freedom of movement. When you stand still they drape down over your legs, sure, but if you lift your leg up (to kick, for example) the coat doesn’t get in the way of that. You don’t have to shuffle your feet in smaller steps when you walk, you’re free to make full strides.[/quote]
Hah, tell that to my ~30lb leather trenchcoat 
Yes we’d ideally have accurate coverage, encumbrance, warmth, etc values broken out per part, but it seems like a lot of work for a very small amount of value.[/quote]
That might be the problem right there: leather trenchcoats are thicker and bulkier (and heavier) than fabric ones.
/KA101, whose insulated fabric trenchcoat doesn’t get in his way, and isn’t split up the back either
