I guess to protect from cold temperatures, you need thickness. These gloves will keep your hands warm, but they are a little bulky for shifting and braking. Maybe they will get more flexible with use over time. Seem to be well-made and up to the usually excellent Castelli quality.
For cold weather, none better
Cycling in the cold and rain of PDX makes a good set of gloves a must. The castelli estremo glove has kept my hands warm enough to enjoy rides in the less than ideal winter weather in Portland. The fleece liner is soft and warm, the closure around the wrist holds secure, there is ample grip on the palm and fingers so you can keep hold of the handlebars in wet and rainy conditions.
Recently after freezing my hands on a road bike ride I determined I really needed a good set of cold weather gloves. The Castelli Men's Estremo Glove is exactly what I needed! Now my hands stay warm on cold weather rides! Highly recommended!!
9 1/4 palm size large fit perfect. great feeling glove but my fingers still got cold after 45 minutes in the low 40's. However my fingers get cold in lobster gloves.
These gloves are very warm for winter riding down into the 20's with padded palms and nice silicone grip texture. Not too bulky for operating shifters and droper.
Love these, but it needs to be COLD out. So if you have cold hands, these are for you. Finger dexterity is good for such a warm glove.
Not warm enough
Superb gloves. Perform flawlessly
Even with modest bulk, the Castelli Estremo glove is easy to grip handlebars, brake hoods or push shifters. These gloves are a superb and uber effective choice to keep cold-prone hands/fingers toasty warm even on the chilliest rides, road, gravel or mountain. So very happy to have them in my cold weather cycling clothing arsenal!
Super cold days I use Pogies, but as the temps get above freezing I move to my lobsters and now these Extremo gloves.
Nice and warm, found my hands overheating at times above 40F.
My one negative is that when hands are moist the inner liner can displace from the fingers when you remove them. It can take some tugging and wiggling to get the hand back in, not something you want to be doing while pedaling.
Just purchased my second pair. Fingers usually stay warm and dry. I order a size or two larger than expected, which is typical for Castelli sizing in most of their gear. These are excellent all-winter riding gloves. They sop of winter nose drips well, too. Material around outside fingers starting to wear after third season of heavy use but this hasn't affected their use.
These are great gloves, and very well made like most Castelli products. Good for me down to 40, then I use silk glove liners inside. Good for working levers for a large insulated glove. Great at keeping wind out.
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.
Spokane weather a good test and the gloves worked great
I wear the gloves in extremely frigid temperatures to work out in outside and also when riding my bicycle in freezing conditions.
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.
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.
