Query: Dangerous, junk!!!!

These are okay if you lift light weights. First thing, the yellow velcro closure on the back had only 1 stitch and ripped off after 2nd use. The worst thing is the grip...little to none. Do not lift heavy weights or deadlift with these, they slip!! They simply do not hold the metal bar. I went back to my old worn out gloves that had leather palms...until I can get some new decent ones. Be wary... spend more if you lift heavy!!
