I feel that on a super still ,cold crisp evening, a late season buck is going to hear you try drawing with a typical puffy even under fleece etc. Not always, but sometimes. The kuiu Kenai would definitely be the first one I'd try that way tho. It's very soft and quiet and surprisingly warm. Cold add the Kenai vest on extra cold days. Or a cordless Milwaukee heated vest.
If your rifle hunting, disregard.
