Блузон из шерстяного канваса (max)
Hmm, need to be careful: "max" is not in the dictionary; "canvas" is "канвас" per dictionary. "Wool" → "шерсть". "blouson" → "блузон" is a fashion term (blouson = куртка-блузон). Category is JACKET, so a blouson jacket is fine. "max" is unknown — it's an English word meaning "maximum", which in this context likely is a qualifier (Max is also a weight/feature?). Since its meaning is unclear, omit it per rule 7.
Result: "Блузон из шерсти канвас" — "канвас" is dictionary term for canvas. Better: "Блузон из шерстяного канваса" — but dictionary says canvas → канвас; "шерстяной канвас" grammatically fine.
