These gloves are great!

  • Familiarity: I've put it through the wringer

These gloves are frequently used in temps in the mid 30s and my hands stay decently warm, actually. They fit well, have held up well over the winter, and look nice. I would buy these gloves over and over again if need be. A worthwhile winter riding glove.

Only good to around 40/45 deg F

  • Familiarity: I've used it several times

I got these thinking they would would be warm enough for late Fall / early Spring riding in Chicago. They are not that warm - even with the Thinsulate and Windstopper. Other brands make much thinner gloves that are a lot warmer, i.e. Pearl Izumi, Craft. These gloves were also severely disappointing in the wind. I took them out to Northern CA for Winter riding there and I thought they were Ok. Temps were never below 45. They look nice and are well constructed, but if you live somewhere that regularly gets below 40, I would look else where.

Not that warm and odd proportions

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small

These were not as warm as I had thought - for late-winter riding on the east coast (30s-low 40s) these would not cut it. Another con is that the only padding is on the side palm- multiple touch points for padding would be better. Lastly, the sizing proportion seems to be off. I have quite small hands and while the S fit generally ok, the index fingers were too small/seams were harsh.

FANTASTIC for cold weather riding

  • Familiarity: I've put it through the wringer

Boy have I loved these gloves. My hands were getting so cold on rides so I indulged in these gloves and have NOT be disappointed at all. I was a bit nervous they might be too cold in the fingers but they are really wonderful. Worth every penny. I love Castelli stuff...plan on buying all my gear now in Castelli or Gore. My 2 new favorites.

i need the warmest gloves for 30 degrees...

Best Answer

For the warmest gloves, you'll want a style called "lobster claw". They are like mittens for bike use, and work the same way as regular mittens, only the fingers are divided into 2 separate compartment keeping each 'set' of fingers warmer than if each were separate. So, that would be the first thing to look for. Something to help block wind/wetness, too, plus of course, excellent insulation.

Hope this Helps for Your Next Winter Riding Season!
