I've been using these for rides and also tried them out cross country skiing recently - worked super well! Below about 30-35 degrees F you may need something heavier, but the wind blocking on the outer part of the hand really helps and I was comfy throughout the rides and ski time.
I wrote a previous review that was critical of the durability of their thermal gloves. I greeted with a personal email asking for me to return the gloves (at no cost) for a replacement. This was above an beyond the expectation and a true example of customer service done the right way. I have been searching for a cycling/tri brand that I can not only love their product but feel a true connection to their mission and proud to wear their brand. Needless to say that no matter how the new gloves workout for me (I loved the fit and feel by the way) I will be trying out more of their gear in the near future.
