Castelli Thermoflex Armwarmers - AW18


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.



  • Thermoflex fabric for soft, warm, stretchy comfort
  • Microfiber gripper elastic at top
  • Sublimated Castelli logo
  • Suitable for a temperature range of 10 - 20°C
Terry Very nice soft material with warm fleecy backing. Normally I take large in Castelli but I have skinny arms and the medium fit well. Usual excellent service from Merlin.
ADAM Snug fit and keeps your arms warm when they need to.
Daniel Love this product......what did I do before I had these??
Scot Love these armwarmers. Just the right amount of insulation so I don't have to wear a jacket.
Mrs Paleomitros Large size fitting well. I am 85 kgr with 1.85 height.
Happy OC Gal Stylish, not bulky, and warm. I ordered L for my husband and S for myself. We are both very happy.
GP 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.,
David 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. Recommended.
Gregory 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.
Mr Jerry High quality product. I recommend it.
Mr Mistry Keeps the chill off nicely in cool conditions.
Paul I`ve got a pair of Assos arm warmer thinking they would be the best. These beat them hands down, very flexible and warm
Cyclodad Nicely made and comfortable fit
