You'll be glad you stashed the Pearl Izumi Women's P.R.O. Aero Jacket in your shirt pocket if you roll out on a warm, clear afternoon without a forecast check. Zip it up, and you'll instantly notice the breathability and flexibility of the supple Softshell Lite fabric as it effectively fends off wind and light rain. Unlike your bunching rain shell or overly breathable fleece, the P.R.O. Aero Jacket is a best-of-both-worlds alternative.

• Softshell Lite is a highly breathable, packable, four-way stretch material that blocks wind and light rain
  
• Tapered collar blocks wind at the back of your neck and won't rub your throat the wrong way
  
• Internal draft flap fends off a cool breeze through the zipper
  
• Direct-Vent panels in high-heat areas add breathability to virtually eliminate a clammy feel
