I had a few questions about the sterile burn dressing. You mention that the can be used as a barrier mask, can you talk more about that? Has anyone tested the washability? I’ve also found a less expensive version on a different website, but can’t tell if it’s the same product, is anyone able to weight in on that, or help me spot the difference? https://www.chinookmed.com/100191/dry-sterile-burn-dressing-and-super-combat-cravat.html
