The suit is fine, since it has SFI 3-2A/1 certification - provided you have approved underwear to go with it. Unfortunately, the ad for the underwear is so damned non-specific, I would have to wonder if it passes muster. The GCR says nothing about SFI labels on underwear, instead being specific relative to material and/or brand name. The underwear ad doesn't give you any information about material or branding, only that passing mention of an SFI label that is meaningless within the context of the GCR.
