Hard, gymnastic mixed climbs with their divots, creases, and corners lend themselves to monopoint crampons. Dual-point crampons, conversely, are more stable on ice and hold better in rotten chandelier ice, crud, and snow, making them the choice for long routes, which can change character from one pitch to the next. In warmish conditions on sport mixed crags, consider forgoing the heavy garb and dressing down in standard sport-climbing ware like tights and a stretch pullover. For gloves, wear the minimum thickness that will keep your hands warm. Some climbers use leather gloves or thin, rubberized jobs that give a firm grip on ice tools, rock, and ice.
Mittens are generally out, except for donning at cold belays.
How you dress is almost as important as what you wear. The theme here is low bulk. Tuck your jacket and jacket shell under your harness so you can easily access racking loops. Likewise, wear close-fitting gaiters over your fleece or shell pants to keep your pant cuffs out of the way of hungry front points. Some climbers carry light and versatile hexes in place of heavier cams.
