Brooks Running Dash Arm Warmer

The draw: Extra warmth that easily tucks away

Wear these during that in-between period where it’s not quite warm enough to wear a T-shirt, but not cold enough to justify a jacket. The fabric is buttery soft, and the warmers fold up small so you can easily pocket them when you heat up. Silicone grippers at the top of the arms and thumbholes help keep them in place but make size selection important for a perfect fit.
