I bought the non-insulated bibs. I have a pair of flannel lined Dickies bibs for work and they are too warm. I sweat during snow removal activities. I bought these specifically for snow removal around the house. They work perfectly, they keep me warm, but not sweaty. Tons of pockets for tools too. On a side note, I am a 36x30 pant size and I ordered 38x30 bibs. With a hoody and undershirt, the bibs fit snuggly, but not uncomfortably. Be aware to go up a waist size, given the clothes worn under.
