Many of my alpine gloves and mittens come with cords to attach them to your wrists so you don't drop them.
I don't use these cords, and I've never dropped a glove while climbing. I just remove these cords (and cut off the little buckles that hold the gloves together too.)
When I take a glove off, I generally just stuff it down the front of my jacket.
Do other climbers use these cords? Do you find it useful to have a cord so your gloves can dangle when not on your hands?
