Your undersuit or anyone elses, it matters not. I do not like onsies. I don't think they're comfortable, I don't want one. I'm glad that you want to keep your customers happy and satisfied, but at this point I'll never be one just on principle. What do you not understand about that? And no thank you on the warmers, I'll stick to my Woodcrafts. Best in the business as far as I'm concerned and I have no reason to change. Worth every penny I barely paid for them.
