Winter cycling doesn't have to mean freezing your legs off. The Castelli Velocissimo 4 tights are designed specifically for those chilly rides where the temperature is hovering between a crisp 6 to 12 degrees Celsius (that's 43 to 53°F for my fellow Americans). They're super lightweight but surprisingly warm, thanks to this awesome Thermoflex fabric that's brushed on the inside with a soft fleece lining. It feels cozy against your skin without being bulky or restrictive, so you still get a great range of motion on the bike. A key thing to note: these tights don't have a built-in chamois (seat pad). That makes them incredibly versatile – you wear your favorite bike shorts with a chamois underneath, and these go right over top. This also means they're super comfortable for walking around off the bike. They've got reflective details on the legs and rear for visibility in low light, and the best feature for many: ankle zippers! These 'Camlock' zippers make getting the tight-fitting ankles on and off over your feet and shoes so much easier. No more struggling. If you're a road cyclist who braves the cooler months, these are a fantastic, high-quality layer to keep you pedaling in comfort.
