Definitely warm, down to at least mid-40's F and probably below that, yet with the dexterity needed to work the brakes and shifters. I have some XC skiing gloves which are very warm but too clumsy for cycling. And mittens, which would be even warmer, offer even less dexterity. Be aware that insulated gloves like these can't work on touch screens.
I bought these gloves for winter commuting in Chicago. I have worn then down to the lower teens, very comfortable and warm. They are bit pricey but they are the right balance between warmth and bulk, they are very light and have good grip. The extended cuff works great keeping wind out of my sleeves. Definitely wind proof, plenty of Chicago wind to test that.
The only thing I would like to see improved is to make the fingertips compatible with touchscreens.
Ive used these on three, 3-hour rides in temps from 25-45F and they have worked perfectly. Not too bulky for di2 shifting, and plenty warm. Very grippy palms and fingers. Great balance between insulation and breathability. Not touchscreen compatible. Sizing runs true.
If I had a nickle for every pair of gloves I've purchased I'd be rich! I struggle finding full-fingered gloves that fit - sometimes the fingers in the womens gloves aren't long enough. And I struggle finding gloves that keep my hands warm in the 30-40 deg temps (I have heated gloves for colder than 30 deg). I was wearing a pair of Castelli Womens cw 4.0 Donna gloves however they're no longer being made. The gloves fit, well, like a glove. Castelli tends to run small so in a womens glove I order a large. And sometimes in womens gloves they're wimpy, as if women won't ride when it's cold so sometimes I'll order mens gloves. Based on the sizing charts and comments that the Estremo gloves run small, along with Castelli's trend to run small, I decided to go with a mens medium and the fit was perfect. However, there were a couple of features I didn't care for, hence, only a 3-star rating. The finger length is spot on however there's probably a 12 of insulation at the fingertip ends so getting that finger feel is missing. It's also awkward getting them closed at the wrist and underneath the jacket cuff. The cuff is a very tight fit so not much if anything fits underneath it. Plus the loftiness at the end of the fingertips makes for a time-consuming closure. The gloves are warm, no doubt, and I do plan to wear them but they won't be my go-to when the temps are in the mid-30s.
Great wrist coverage and pretty good fit for me. They are tight on the end of my thumbs, but so are all my gloves and mittens. My thumb tips get cold pretty much no matter what. I've used these with temps as low as 30F and am satisfied with them. Little grippy features on the palm side is nice and reflective accents, too.
These were a Christmas gift from my kids this year. They were a very welcome upgrade from my previous winter gloves, the Castelli Chiros. The Chiros still serve me well from 40 - 50ish degrees, but the Estremos have been a necessary addition when the temp drops below 40. They are super comfortable. Great feel. Cozy warm. Perfect fit. I can't yet vouch for how water proof they are on extended rides in a steady rain. Still, my hands have been dry and warm in light, intermittent rain with temps around 40. In dry weather, I've used them down to 30 degrees. I wouldn't say my hands were toasty, but I was comfortable enough.
While I don't believe anyone will ever create the perfect winter glove, these have proved to be better than many in my arsenal. I have worn these comfortably down to the freezing mark, below that I would add a wool liner or switch to a lobster claw. Above 45F (7C) I would go with something lighter. These feel solid and well-made and the long cuffs prevent gaps and help keep the cold out.
Good gloves. The velcro tab is a little hard to manipulate with the gloves on.
In extreme cold you might need to put on some thin liners in addition to these gloves.
In respect to appearance, these gloves look nice and of excellent quality.
They keep my hands warm still some tingle at end of fingers. Have used them in the 20's they did okay. Today temp was in the low 30's and they kept my hands warm. They are better then PI lobster gloves. I also own Planet Bike Borealis lobster gloves and they keep my hands warm.
Have on order from Dicks store a pair of Seirus Heatwave Liner gloves. Still looking for the perfect glove.
These are marketed as very warm gloves on the coldest rides. I think Castelli needs to clarify what they interpret by the coldest rides. If you are talking about 40 degree temps these work okay. If you are talking about anything colder, recommend you look elsewhere. They are well made, but not overly warm.
I'm super-impressed by these gloves. They have not only kept my hands warm on rides around the freezing level, but literally sweating. Even when my toes have been numb, my fingers are toasty. I don't think you'd want to ride in them much above 45 or 50, but for those cold rides, they are perfect. As others have said, order a size or two above what you think I have average to small hands, and large fits pretty snugly. I was worried at first about the tight fit and heat loss, but that has NOT been a problem. The fingers are a little bulky, but if want to be warm, it's a small price to pay. Hugely recommend!
The early morning temps on my commutes the past two weeks have been in the twenties and even in the teens. Nothing keeps my numbs . . . I mean my thumbs warm. However, these are really nice gloves. Wrist coverage can be a problem for my long arms in riding position, but these provide enough coverage. I like everything about them except that the right thumb is annoyingly short and I feel like the web between thumb and forefinger is restricted therefore when reaching for the brake. It's an annoyance I'll probably tolerate until they wear out.
Costello gloves fit my hands really well. I wear a medium and other brands tend to be just a little big and small are to tight. Costello are perfect. I have bought a few gloves for winter and always find my fingertips still get frosty. These gloves are warm and as far as being bulky, no worse than any other winter glove. I ride a Di2 bike and have a great feel for the shifting and am able to use my Garmin remote mounted on the inside of my hood as well with no problems. These were pricey but in terms of effectiveness and fit, I have already spent twice that on competitors gloves with less than favorable results. Costello is really becoming a brand I can trust for fit and quality. These are worth a look if your hands get cold with other gloves.
