awesome arm warmers

(Casual/ Recreational) October 27, 2014

These add versitility to the changing temperatures of mountain ultra runs. They are light wieght and easy on and off when you are running. Easy to carry over lots of miles. My favorite thing with these above the several others I have tried is that they actually stay up and are small enough for my arms!

  • Comfortable
  • Dry Easily
  • Durable
  • Warm
  • Wicking
  • Sizing: Feels true to size
