Getting perfect conditions is tough. Fortunately, there are fans to cool the body, dry the holds, and make it easier to breathe in a stagnant bouldering zone. This summer, I hiked my 5.5-lb Makita Jobsite fan to Bierstadt, a V10 compression problem in Mount Evans, Colorado. The battery lasted far longer than my three-hour session even when placed on high. (The fan works on Makita’s universal cordless battery pack.) The tilt allowed me to angle a slight breeze onto the crux holds, which made them infinitely stickier. But best of all was putting the fan on my back for the steep, two-mile uphill hike out. The tailwind helped me set a PR back to the car! MSRP: $92
