There's nothing worse than having all of the right layers on your legs and torso, heading out to ride, and an hour later realizing that you're barely able to bend your fingers at the shifters. Nothing to fear, though, as windproof, insulated gloves like Castelli's CW.3.1 Gloves will keep your fingers moving through the depths of winter.
The CW.3.1 gloves were constructed from several layers of advanced materials. The shell is a windproof and 10,000mm waterproof fabric that's also highly breathable. So, while you're blocking moisture out from outside, you won't be left drowning on the inside. The second layer was made from 100g Thinsulate for warmth, while the entire glove has been lined with Bemberg fleece for comfort. That's right, Castelli covered all of its bases with this design.
For extra security on wet or slippery roads, an all-over silicone print was placed on the palms for grip. Castelli also added reflective accents to the gloves, increasing your visibility to motorists in low-light conditions.
The Castelli CW.3.1 Gloves are available in five sizes from Small to XX-Large and in the colors Black/red, Red/white, and Black/yellow fluo.
It's been colder than a brass toilet seat in Portland and these are easily the warmest gloves I've used for biking. Actually they're so warm I could probably use them for snowshoeing too. The Polartec lining really insulates but is thin enough that I don't feel like I'm holding onto my handlebars with overstuffed oven mitts like with some other winter-weight gloves. In 25+ mph headwinds they remain windproof and dry in steady rain or light showers (haven't had to test them in heavy downpour). Shifting, adjusting zippers, and pulling things out of my jersey pockets are painless. I tend to run cold but even I can't wear these when it's warmer than 45F otherwise my hands get pretty sweaty and I start to overheat. Seams are well placed with no rubbing, very grippy silicone palms, and like most Castelli items they're very aesthetically appealing. Only 4 stars cuz no matter what surface I try they can't activate the touchscreen on my iPhone, the reflective hits on your pinkies don't really light up that much in low light, and they're made in China.
