One of the factors that has prevented me from getting insulated gloves is that in the shoulder seasons, while it might be 40 degrees during my morning commute, it often warms up to 70 by the time I ride home. Who wants to carry two pairs of gloves with them? The DeerSport PCis feature Outlast phase-change material to help modulate body temperature. The material, which was originally developed for NASA as a lining for space suits, has loads of tiny capsules that are filled with a material that absorbs, stores, and releases heat by changing phase from liquid to solid and back again, depending on the temperature. The material stores heat when you need it and releases it when you don’t, for a broad operating window between around 35 and 75 degrees. Furthermore, with heated grips, rather than shielding hands from the warmth the way some insulating materials can, the Outlast material absorbs heat, even radiating it around the fingers.
