Were ready for unpredictable weather with the Oiselle Whirlwind Jacketa technical shell built for runners who embrace every mile, rain or shine. Crafted from wind- and water-resistant ripstop polyester, this lightweight jacket keeps us protected when the skies shift, without weighing us down. The thoughtful design makes it a trail and road essential: a full-zip front and elastic-bound hood offer quick coverage, while the longer rear hem keeps the elements off our back. Zippered hand pockets and an internal drop-in pocket secure small essentials, and when the sun reappears, the whole jacket packs neatly into its right pocket with an arm band for hands-free carry. Built with bluesign®-approved materials, the Whirlwind combines performance, packability, and eco-conscious construction for runners who go the distance. material: 100% polyester insulation: none fit: regular length: hip hood: yes
