Regardless of where you stand on the warmers vs. tights debate, the versatility of classic leg warmers like Sugoi's MidZero Leg Warmers is impossible to refute. The MidZero material is a lightly brushed fleece that provides the kind of flexibility and breathability that even the most well-meaning windproof membranes can only dream of. This means it's ideal for days in the mid- to low-50s when you need full coverage but anything heavier would be stifling overkill. Combining thermal warmers with regular shorts has the added benefit of protecting your knees and shins without adding unneeded insulation to your core. After all, that's where your engine is. It may be chilly when you set out in 50 degrees, but your core will warm up after the first 15 minutes of the ride. Too much insulation after that will leave you uncomfortably sweaty, a fate warmers can help you avoid by simply taking them off and stowing them. Unless you're wearing a pair of shorts underneath or live in a decidedly permissive community, we don't recommend trying that with thermal tights.
