We tested a couple different kinds of gloves and mittens. Both worked well unless they were too thick – you want a relatively thin material here. A little grippy stuff on the palms and fingers is helpful. Mittens are typically warmer than gloves, and you don’t need to be able to separate your fingers to do CrossFit.
Note that these worked well for things that are not excessively grip-intensive. Specifically we didn’t test a glove that would allow for heavy pulling (deadlifts, heavy snatches/cleans) or kipping movements. But, these gloves should work for dumbbell and kettlebell work, lighter snatches and cleans, and strict pull-ups, strict toes-to-bar, etc.
We like these options —
