The Herman Survivors Brand was established in 1879. These Waterproof Slip Resistant CAMO BOOTS are made with Thinsulate-made up of 600 grams of Ultra Insulation! They also come with patented Sympa Tex & Scent Mask. (No Smells here!) I’m only selling them because my foot grew. Still with many many miles of good wear left!. I feel the price is fair, but I’ve been out of work awhile & open to ALL reasonable offers.
