The Details

The Castelli Thermoflex 2 Arm Warmers are soft and insulating and made from luxurious fabric to keep you protected in cooler days.

Perfect if you don’t need wet weather protection, the Thermoflex 2 fabric has a super soft finish that has been achieved through Castelli’s meticulous research and development.

The fabric used in this cycle clothing feels super comfortable against the skin, with the loft trapping just the right amount of air above the skin to keep your heat regulated through autumn, winter and spring conditions.

Finished with a discreet black embossed Castelli wordmark logo and silicone grippers on the upper edge to keep the warmers securely in place. Single-seam construction and flatlock stitching create a low-profile look and feel.

  • Thermoflex 2 fabric for exceptional warmth and softness
  • Minimal seam construction for aesthetic versatility and freedom of movement
  • Easily packable into a pocket
  • Highly breathable but also insulating
  • Optimal temperature range is 8c - 20c

Our Verdict
