Black Mamba gloves are made with a patented nitrex polymer which makes them stronger then comparable latex gloves.  They were made in demand of a disposable glove that was tough enough to withstand tough tasks.  There is no longer a need to change your glove multiple times due to ripping or tearing.  These gloves are made to grip and not to slip with a fully textured Grip Rite finish.  Yoder Oil carries Black Mamba gloves in Small, Medium, Large, X-Large, XX-Large and XXX-Large.  If you have questions on this product please contact our customer service department and they will provide you with a solution.
