DriLayer 88% polyester/12% spandex
To keep your Brooks gear looking and performing its best, machine wash separately before wearing, try not to use fabric softeners, and tumble dry on low heat.
The DriLayer® fabric feels incredibly soft, wicks away sweat, and keeps you comfortable and dry.
Not too light and not too heavy, layer it on for just-right warmth.
Envelope pocket at left wrist stores your ID and credit card for that post-run beverage.
