I will echo Land's End for warm winter jackets, but for a canvas work coat I would instead suggest Patagonia. They have a great canvas chore jacket and will do repairs if needed. I'd really suggest two coats so that you don't have to worry about getting your good workin coat dirty and then still feeling frumpy anyhow. Fix up the Kuhl and keep it as your chore jacket! Come visit us over at r/Visiblemending if you need ideas or suggestions.

Carhartt makes a women's chore jacket but the cut is weird and the arms are too tight for actually working in. Tough Duck is a bit better as well as cheaper. The Patagonia one is more expensive, but a better coat all around for doing things like splitting wood where you want some mobility but also don't want to pick splinters out of the fabric for eternity.
