When Castelli designed the Thermoflex armwarmers they concentrated on getting everything just right. The Thermoflex fabric is extra warm and stretchy, the close fit eliminates any excess fabric and the silicone grippers at the top prevents the warmers from gradually slipping down. With a cross-wrap cuff at the bottom Castelli have included an extra touch of comfort while subtle branding lets your cycling friends know you’re wearing kit made by one of the premier clothing brands in cycling.

Stylish, not bulky, and warm. I ordered L for my husband and S for myself. We are both very happy.
These are really nice, they feel warm due to the lining without being too warm on the bike and really stop the early morning cold getting to your arms. They also seem to keep the sweat away unlike my previous pair from another brand. Recommended.,
Superb, great quality arm warmers. I ordered the xxl as I'm 6'02" tall and reasonably muscular. They arrived and I was very pleased as they are snug but not tight. The fleece liner is comfortable and the are long so stretch from the wrist above the level of Jersey sleeves.
Castelli products are awesome, form-fitting and sized just right, especially for someone who is vertically-challenged/short/small like me! The quality of fabric is superb as well and Italian styling goes a long way in my book. I'm very happy with my purchase.
High quality product. I recommend it.
Keeps the chill off nicely in cool conditions.
I`ve got a pair of Assos arm warmer thinking they would be the best. These beat them hands down, very flexible and warm
