The Chippewa Bay Apache Waterproof Insulated Steel Toe Super Logger has 400 gram Thinsulate insulation, Chip-A-Tex waterproof membrane, and the Bay Apache waterproof leather to keep your feet warm and dry. It also has a ASTM F2413-05 steel toe and is ASTM electrical hazard rated.

	Just like regular Thinsulate it is lightweight, breathable and moisture-resistant. But Thinsulate Ultra insulation goes one step further. It is loftier and thicker than original Thinsulate insulation-for even greater warmth and comfort, yet still thin enough to allow complete freedom of movement. A mid-loft insulation, it is designed for some of the harshest conditions on earth and retains insulating value in damp conditions.
	The Chip-A-Tex waterproof membrane system is breathable. Water is locked out of the boot by the membrane shield but air passes through from the foot for maximum comfort.
	Vibram is the world leader in high performance rubber soles, targeted to the outdoor, work, recreation, fashion, repair and orthopedic markets.
	Dri-Lex delivers heightened comfort through a moisture management lining system that is totally breathable and quick drying.
	Steel safety toe cap meets or exceeds ASTM 2413-05 standards for impact and compression.
	Non electrical conduction of electrical potential or magnetic charges. Safety toe cap meets or exceeds ASTM 2413-05 standards for impact and compression.
