Forget frozen fingers.

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.

Really could not be better.

  • Familiarity: I've put it through the wringer

I have been using these gloves for about 2 months now, for daily bike commuting in Seattle. That has involved a lot of rain (rarely a downpour, but often in steady rain for 30-45 minutes at a stretch), a fair bit of high winds/high speed downhills, and temps only getting down into the high 30s, more often in the 40s. I have been blown away by the quality of wind-proofing - nothing gets through, whether it's dry or wet. Similarly, I have yet to experience the rain penetrating. The level of insulation is spot on for my climate/usage; on sustained climbs, my hands definitely start to overheat, but I tend to run hot, so this is very much to be expected. They are very comfortable, and there's very reasonable articulation/feel for the handlebars/brakes/shifters. Finally, the build quality feels excellent so far. As I mentioned, have only used them for 2 months of twice daily usage so far, so not exactly a long-term test, but they feel extremely sturdy/well-made. All in all, for what these are - extremely windproof, extremely waterproof, with insulation appropriate for chilly but above-zero temps - I really could not ask for these to be any different or better.

Also, I think a review from 2013 mentioned a lack of snot pad - that has totally been remedied, there are large and well-textured snot pads on the back of the thumbs (they get a lot of use from me).

Too good??

  • Fit: True to size

A remarkable product - first gloves I've owned where my hands never felt less than warm in temps in the 30's (sorry, that's about as low as it gets in Florida).

Hot Hand

Best buy ever for cold weather riding. The fleece like liner keeps hands warm and the contact feel to bars not too distant. You get a pretty good feel. Do not wear these in intermediate weather ranges or you'll sweat like a sinner in church. Otherwise, these things rock!

Great cold weather gloves

  • Familiarity: I've put it through the wringer

I've used these gloves through last winter and liked them so well I ordered a pair for my wife. They are extremely good at keeping your hands warm without all the bulk. They keep me warm but still allow me to feel the bars and work the shifters with some sense of touch.

Winter-grade protection.

  • Familiarity: I've put it through the wringer

I've now used the CW.3.1 gloves in late fall, through winter, and into the spring racing season. They've done the trick in conditions ranging from the low-30s and dry to 42 with moderate rain. My hands got cold in the low-30s, but not to the point of discomfort, and I find that any temps over 45 are way too hot. Break out the classic knit gloves for that. As for rain, it doesn't stand a chance--my hands have never gotten wet in these, and I've given the rain several opportunities to make its case.

I've trained in them and raced in them, and the only real complaint I have is that fumbling at Honey Stinger packages mid-race in them can be a bit awkward. Of course, they're still far better than your typical ski glove, and bar and shifter feel stays about as solid as you can reasonably expect it to while still protecting your hands.

Finally, a note on fit. My admittedly limited experience with Castelli indicates that its kit typically runs small across the board. In most gloves, I'm an XL, but for these I sent the XL back in favor of an XXL. When in doubt, I recommend sizing up, because I hate riding in gloves whose index finger and thumb are too short.

Winter-grade protection.

Great for colder temps.

  • Familiarity: I've used it several times

These gloves have been the best winter gloves that I have owned so far. They are not bulky and are very effective, I usually have a hard time keeping my hands warm but I have not had to use liners with these even when the temps went below 36*

how to measure the hand

Measure from the inside tip of your longest finger, to the crease at the base of your palm, where your hand meets your wrist.


  • Familiarity: I've used it several times

So far so good. Road riding in dry 38-48 degree temps and these Castelli gloves are fantastic. Very warm and ergonomic. I agree with other reviewers that these gloves will get hot as you approach 50 degrees. A few negative topics worth noting ... the palm padding is next to none and there is no soft area on back of thumb for nose wiping. C'mon, don't we all need that? Additionally, the palm side of the glove is generally lacking in reinforcement. I would have liked to see a larger leather patch in the area of the thumb webbing. Besides that, I do like the gloves and they do what I wanted. Warm hands on winter rides. I think the amount of insulation is near perfect for the range I described and I run a bit cold at the extremities.

Cold weather, hot hands

  • Familiarity: I've used it several times

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.
