If I try to warm my entire whse, I spend $10k/month to try to make it tolerable for a 12 hour shift. I tried heated Battery vests from New Zeland, but they just don't provide enough warmth. Full up insulated coveralls with extra clothes for warmth, are cumbersome, heavy and limit movement. How about a full up, high quality MC suit? Aerostich? Are they warm without bulk? Compare to a heavy Carhart? I need 8 of them, but 8k on suits is better than 10k/month for 4-5 months of cold work environment.
