One thing to keep in mind when shopping for these scent elimination suits is that they have a fairly limited lifespan- I think it's 2-3 years of moderate use. After that they become just another camo suit. There was a good thread on bowsite about this recently...

A more cost effective solution would be to get a liner that you can wear under your camo. It'll cost a lot less than the camo suit, so it won't hurt quite as much when you have to replace it in a couple of years.
