These grips offer great tack when it comes to grabbing a pullup bar. I have not torn a single callous since I started using them! One specific area in which they excel is muscle-ups. They make a noticeable difference, and I am able to string more together because they minimize hand/grip pain through all of that torque. They're thin in a good way so you don't notice their presence, offering a natural feel, but they're also incredibly durable. The only sign of usage on them is the chalk! I actually tend to leave them on when I transition to a dumbbell or a barbell, which is not the case with other, bulkier grips that I have used. They are an incredible, versatile pair of grips that I would highly recommend to anyone in the market.
