The Thermoflex Armwarmer from Castelli is composed of a luxuriously soft and supple fleece-based fabric, Thermoflex. Its tightly woven fibers facilitate insulation by trapping a layer of warm air next to the skin while still providing moderate ventilation. Grippy microfiber along the upper cuff helps keep the Thermoflex Armwarmer firmly in place.

  • Ideal Temp. Range: 8°-18°C (46-64°F).
  • Fabric: Thermoflex.
  • Weight: ~70g (pair)
  • Cross-wrap cuff.
  • Elastic upper arm gripper.

Great versatility, quite warm, easily packed into rear pockets, not sliding on your arm, great even above a loose long sleeve jersey

These have been great for winter mornings in the high 40s, and I leave them on until the temps climb into the mid-50s. When they're on, I forget they're there. When I remove them, they easily stow away in my jersey pocket.

The Castelli Thermoflex Armwarmers are perfect for cool Iowa mornings and easy to roll down as it gets warmer in the day.

I like to ride on county roads when it is dark and cool out. The Castelli Thermoflex Armwarmers kept my arms warm and dry on the coldest of Iowa mornings. The Thermoflex fabric conformed to the shape of my arms, and the length (XL) was perfect for my 6' 3 frame. The Castelli Thermoflex Armwarmers were my first set to own, and I would highly recommend them to any bicycle enthusiast.

These are great arm warmers for chilly to very cold rides. Keep in mind that only one of the two arm warmers comes marked with the Castelli logo shown in the image above, the other arm warmer is just plain black.
