Concerns over scent control have largely been overstated for years in order to sell clothes and products to hunters. It is a far larger scam than trying to convince hunters they need the latest and greatest camo.
Not that it doesn't exist, deer do have a good sense of smell, and some type of camo does help, especially at bow hunting ranges. But I don't obsess over either. I take reasonable precautions to keep scent to a minimum, and I often wear camo, but neither is going to make or break a hunt.
