Brass Knuckle® SmartFlex™ BK315 is a 13-gauge polyester work glove with a latex crinkle coat on full fingers and palm. 


About the glove 
Polyester is very affordable, feels soft to the skin, is durable, and offers excellent resistance to abrasion. Polyester is launderable and is more resistant to color fading caused by sunlight. Finally, it’s a more stretchable fabric, which means you can size this glove down to create a more snug, dextrous fit.

The latex coating offers high elasticity plus improved abrasion and puncture resistance. The crinkle pattern increases surface-to-surface contact area, thus improving grip — particularly the wet grip. Latex is not recommended for oily applications, but this glove is an excellent dry or wet gripper virtually anywhere else.

In black-on-black, this affordable, durable glove looks tough and works even tougher.


  • Latex coating on full fingers and palm. Offers high elasticity and outstanding dry and wet grip. Durable, with improved puncture resistance. Coating remains soft in cold conditions.
  • Crinkle grip pattern enhances dry and wet grip, improving dexterity. Excellent abrasion resistance. Latex is a breathable coating, helping to keep hands cool.
  • 13-gauge, 100% polyester knit liner. Launders easily, resists shrinking and color fading. Provides superior warmth without bulk.
  • Breathable and stretchable. Excellent tear resistance.
  • Glove offers second-skin fit, thus enhancing function. Black-on-black style conceals dirt.
  • A full knit wrist — seamless and stretchable — helps prevent dirt, debris, and cold air from getting inside glove.
