Magid CutMaster sleeves, crafted from 100% machine-knit Para-Aramid in an extra-wide design with a thumb slot, deliver superior protection against cuts, punctures, abrasions, heat, and flames. This material is five times stronger than steel by weight, enabling the double-layered construction to achieve an ANSI Cut Level 4 rating under US ANSI ASTM F-1790-97 standards. These sleeves maintain their protective qualities and experience minimal shrinkage even after washing. Each yellow, seamless unit includes an overcast edge to stop fraying. Offered in a 3 1/2" width with lengths of 18", 21", or 24", they ensure a comfortable, non-obstructive fit. The integrated thumb slot enhances hand safety, keeps the sleeve secure, and preserves user agility and dexterity.
