What practical purpose does the smartphone touch function in thin windproof gloves actually serve?

Looking first at the lightweight spec of approximately 4g, these are ultralight windproof gloves designed to block the wind while reducing the feeling of weight on your hands^[1][2]. OZN's Zero: UL Wind Gloves (10D) uses a fabric with a 10D thickness and 27 GSM specification, and DWR treatment has been added to the surface^[3]. DWR is a water-repellent finish that helps water droplets bounce off rather than soak into the surface. Such thin and light fabric does not dull the sensation of your hands, making it easy to open and close backpack zippers or handle gear while wearing the gloves.

The smartphone touch function added to this plays a role in helping maintain uninterrupted hand protection^[4]. It saves you the hassle of having to take off and put your gloves back on every time you check a map at a fork in the trail or take a photo during a trek. hmmm, it is a practical consideration that lets you maintain your hiking stride without stopping, while preserving the warmth of your fingertips even on cold, windy ridges.
