The Bear Komplex Black Diamond No Hole Speed Grips offer the palm protection needed for your toughest workouts. Made with the same patented material found in the Black Diamond 3 Hole grips, these are perfect for Pull Ups, Chest to Bars, Power Cleans, Deadlifts, Snatches, CrossFit Workouts, Gymnastics, and more... The Black Diamond Grips are the stickiest, tackiest, most grippy grips to ever be used for cross-training. Made from a synthetic material, the Black Diamond Grips are great for Powder Coated bars and are versatile for other gymnastic and weightlifting movements. Unlike most grips on the market, Black Diamond Grips do not need chalk to stick to the bar. In fact, don't be surprised when they hardly even hold chalk if you were to try. That's part of the magic of the Black Diamond Grips. The Beak Komplex grips now have a reinforced neoprene layer on the wrist strap for increased comfort. Please note: Bear Komplex grips have a life span of 4 -6 months if used regularly and will eventually wear down due to the forces applied to them when under load. Sizing Guide: 1.  Find your hand/wrist connection.  This is where your hand and wrist meet (you should see a creased line there).  This is the point to start measuring from. 2.  Be sure your hand and fingers are totally straight and flat.  DO NOT cup your hand or stretch your fingers backward. 3.  Measure from the wrist/hand connection (where you see the crease) to the base of your middle finger.  Be precise and don't round up or down.
