Castelli's Chiro Due gloves are good-quality mid-weight gloves for cool autumn/winter days - although not for the very coldest rides.
The Chiros owe much of their performance to the fact that they're made from a Gore Windstopper fabric throughout - and that includes the cuffs. No cold air gets through it. Plus, although these gloves aren't designed to be waterproof, no rain gets through the Windstopper fabric either. It can soak through the seams but not through the fabric itself.
More warmth comes courtesy of Thinsulate insulation that sits between the glove upper and your hand - but not on the less exposed underside . The 40g variety of this fine-fibred synthetic insulation doesn't provide as much warmth as the more weighty versions but it has the advantage of being extremely low bulk.
Castelli give the temperature range of these gloves as 5-10C. I agree with this although, as ever, it'll come down to the individual. (By the way, last time we checked the Castelli website it gave a temperature range of 10-18C for these gloves. That's a mistake.) If you buy a pair with enough room you can always wear liner gloves underneath for extra warmth. With no cold air getting though the Chiros, a pair of thin merino gloves inside will make these useable when the temperature is a few degrees cooler.
The palms and the underside of the fingers are textured Pittard's leather that grips very well and there's a small amount of padding in there. And it really is a small amount. I found that fine on shorter rides but I wanted mitts underneath for extra comfort on rides over about 90mins or so. Again, it'll all come down to your personal preferences on that score.
You get good reinforcement in that section between your thumb and forefinger (does that part of your hand have a proper name? It should) and a useful microsuede panel on the back of each thumb to take care of all your wiping-away needs. That stripe across the back of the hand is reflective and the subtle Scorpion logo is a neat addition.
The only negative comment I have to make is that I often found it difficult to get my hands back inside these gloves if I took them off mid-ride. Say you get a puncture or have to delve into your pockets for some change; you have to take your gloves off. Although the Windstopper fabric is breathable, the soft fleece lining and your hands will inevitably be a little bit damp, and that makes things difficult. It's something you find with loads of close-fitting gloves. Wearing a stretchy liner glove cures it... but you might not want that extra warmth or bulk.
Ah, I do have one other little moan. There are two tiny holes in each of the cuffs where the little bits of plastic that held the merchandise tags went. They're hardly noticeable but still... Grrr!
Mid-weight Windstopper autumn/winter gloves with good warmth for their bulk -the price is steep, though
road.cc test report
Make and model: Castelli Chiro Due Glove
Size tested: Large
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Here's what Castelli say, "Our Chiro glove has been a favorite for years and now gets an update for even better fit and better insulation on the palm making it suitable for a wider range of conditions.
WindStopper fabric throughout
Made for comfort in cold weather riding
Lightly padded textured leather palm
Microsuede thumb panel
There's really not much insulation on the palm although the wind won't get through there. All the Thinsulate is on the back of the hands and the fingers. Those are the exposed bits so it makes sense.
Tell us some more about the technical aspects of the product?
The main fabric is from the Gore Windstopper family which provides lightweight windproofing. Thinsulate 40g provides exceptional warmth for its bulk because of the fine fibres used and their density.
Very impressive, my only problem being getting the gloves on again after taking them off mid-ride.
Well made using excellent materials. Durability won't be a problem
This isn't a mark for their weight as such; more for the amount of warmth they provide given their light weight and lack of bulk.
Windstopper fabrics are generally pricey and Thinsulate is usually a little more expensive than an unbranded equivalent. It's all good stuff... but you're paying a lot for mid-weight gloves
