A must for bio-security protection. Wear into quarantine areas, use for visitors (especially on farm days when visitors will be visiting lots of farms with the same shoes), when visiting other farms and anytime a barrier is desired to reduce the potential transfer of parasites. Preferred by livestock breeders for its quick-apply, no-tie design for easy-on, easy-off convenient protection. Elastic top stretches wide to accommodate large work boots. Clear plastic is durable, lightweight and disposable. Embossed texturing, 3 mil thickness, packaged 25 pair/bag.
