A cool-weather cycling kit is not complete without a set of Arm Warmers like Gore Bike Wear's Universal Thermo. They are made with an optimized mix of nylon and elastane, with a brushed interior that feels great against the skin, and an articulated shape to enhance mobility.

This natural shape assists the elastic band and silicone grippers to keep the warmers firmly in place. It also permits a next-to-skin fit that enhances thermal and wicking properties. Gore Bike Wear also uses flatlock seams throughout the Universal Thermo warmers as another tactic to avoid irritating the skin.

Finally, reflective logos on the sides add low-light safety visibility, and a screen print makes finding left and right easy. The Gore Bike Wear Universal Thermo Arm Warmers come in sizes X-Small through X-Large and in either White or Black.

They fit and won't slip

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

These arm warmers are great. I've got pretty thin arms and always struggle with arm warmers sliding down, even when I order a smaller size. These have a great silicon grip on the upper arm and stay in place. I went with a medium and they are snug without cutting off circulation. If you've got any definition to your arms you'd probably be better off with a large. These work well in the 40's and up, definitely not a winter accessory unless you want them as an extra layer under a jacket.

If I've got any complaint it's that I wish they were a little longer. When pulled all the way up there's a small gap between the end of the warmers and the cuff of my fall/winter gloves.
