I'm very pleased with the quality of these gloves and love wearing them. I have a pair of very similar gloves from another manufacturer and the Assos gloves have a much nicer seamless feel internally which I really appreciate.
I've mostly used them riding in conditions ranging 38-55F and they have been great for that. Colder conditions than that range for me has my hands feeling a bit cold with these gloves. My rides normally start with a steep downhill and on the coldest days I put mitts over these gloves to be a bit warmer until I have completed my descent. I did ride with these gloves in heavy rain once and they got me by, but did eventually soak through and feel squishy though somewhat warm. Specific rain gloves would be a better choice for heavy rain days.
I really like these gloves. They feel quality and look nice. I have worn them several times and they do HELP, but they are not enough for Albuquerque winter temperatures. I think that they'll be great for fall and spring without additional measures.
