(Weaver Leather) Kirk Stierwalt Cattle Neck Sweat System with Flex Foam Liner is an innovative design that can be reused. Black leather neck sweat shell comes with a replaceable Flex Foam liner that is secured in place with heavy-duty hook-and- loop closures. When it's time for a new liner, simply remove the old liner and purchase a replacement, saving the expense of buying an entirely new neck sweat. Black Flex Foam liner retains heat for the perfect sweat while the easy-to-clean channels trap dirt and grime to eliminate build-up on skin. Stierwalt Cattle Neck Sweat System with Flex Foam Liner features nickel plated hardware.
