I need a 40 cal/cm² arc flash suit for live work on 13.8 kV switchgear in an indoor substation. Focus on comfort and full-body protection is a plus. What brand or specific suits do you recommmend for this level of protection?

I can't recommend but do a web search, due diligence etc. Be sure it complies with either ASTM or IEC standards. See where it is made, some counterfeit PPE is out there.

Go with a well-known NFPA-70E / CAT-4 (≥40 cal/cm²) kit from a major vendor that advertises lightweight / breathable fabrics and a good hood option (lift-front or PrismShield) for comfort and full-body protection. Strong candidates are below with why I’d pick them. Try before you buy if possible — fit/mobility matters a lot for live switchgear work; many vendors/distributors will demo or exchange.
