I understand the difference in the cheap sfi1 and the sfi5 suits. My question is why is there such a price difference in the sfi5 suits? I can see a few differences as far as sleeve attachment, quilting, cuff vs. straight cut leg. etc. but there is such a price difference. For example the sparco top end suits range from $1000-1500 and are 3 layers and sfi 5 rated. And the G-force 505 suit is $239 and it is also 3 layers and sfi 5 rated. Then the G-force 545 is $449 and it is 2 layers and also sfi 5 rated. Then you have a variety of suits that fall between the ones that I mentioned. So what warrants the huge price difference? Are you just paying for the Sparco name? Are there features that I should be looking for? I just want a suit that is comfortable and will protect me in a fire without breaking the bank.
