abrasion and flame resistant “smock” for bushwacking/campfire wear?

This is the nearest things I could find that matched your criteria. Except the weight. They ain't that light.

If you mean the silicone rubber treatment made by Nextec called Epic, it makes cotton fabric burn. Tried it out on
various samples they sent me. The synthetic versions such
as "Malibu" seemed harder to light than the cotton ones.

Did it stop burning when flame was removed? Its the ember that melts through shells and releases feathers that I'm worried about.

you need a etaproof jacket maybe from klättermusen

And overkill/heavy and expensive…. Im thinking more along the lines of a xxxl Egyptian cotton dress shirt simplified to a pull over and tec-washed or some such. I guess I would have to dye it OD to look properly bushy.

light wool shirt or sweater. I'd like a light wool jackshirt for car camping myself.

I continued to burn very well. It would make excellent fire
starter. Same with waxed cotton.

light weight and flame resistant simply dont go together.

You could try a Nomex shirt from Forestry Suppliers, but it may not be light enough…

A lot of Minnesota Outward Bound sled dog instructors wore
the old school 60-40 parkas (60 cotton/40 nylon) for use in sub freezing weather in the wind and around fires. Many
sewed coyote around the hood opening like the sourdoughs.

Sportsman's guide has cotton Russian snow camo suits.

I use Swedish surplus snow camo when hot tenting but its heavier than I would like.

I've had ancient Pendleton wool shirts from the Sally that were really thin, not Madras thin but much much thinner than Ive seen available today.

A light wool top layer, thin cheap thrift store wool sweater maybe?

I know old timers swear by them in the bush and by fire.

fire resistant vest/jackets that workers use … you can also get nomex fleece which you can use as part of yr insulation system
