Yes and it would make a big difference to throw in wool trousers with suspenders (no belt, to allow clothes to be worn loose at the waist so that neither circulation nor ventilation is restricted) tucked in decent broken-in boots, a blaze orange (why not) watch cap, gauntlet style mitts (doesn't have to be Gore-Tex). My point is that it's pretty obvious that you should pack a warm jacket or parka but if you're going to wear jeans and tennis shoes it's not consistent. Last week I saw a guy wearing a Canada Goose Expedition parka in the mall downtown (Montréal) and it was raining outside! But he was wearing fashion jeans and sneakers.
