Here’s a simple way to make some glove retainers, crucial if you are to whip your gloves and mitts on and off when climbing. All you need is two lengths of 4mm or 5mm shock cord and two cord grips. Tie one end of the cord through the cord grip with a figure eight or fisherman’s knot, then pass the cord back through the cord grip forming a loop. The other end can then be tied via a strong point or through a hole melted in the hem of the glove.
By pulling on the cord you cinch down the size of the loop, which is best on the forearm so the gloves stay out of the way and the loop is opened by pulling on the cordlock with your teeth. If you’re removing your mitts to carry out a delicate task and don’t want them flapping around in your face, then loosen the loop and slide them up to your shoulders out of the way.
