When the urge to run has you out the door each morning at 5am pounding a swift 5-miler through a densely wooded trail, you’ll definitely want to be wearing The North Face Impulse Pant. These are built to withstand any terrain, in any weather. Made of stretch elastane and double knit fabric, the Impulse Pant offers superior warmth and mobility for your best performance. The VaporWick moisture management system wicks perspiration away from skin, moving it to the outer layer where it quickly evaporates. The leg has a slight boot cut for comfort and flexibility, while hem zips give you even more control. A security pocket is ideal for storing your house key, while reflective logos help give you visibility in dim light situations. The North Face Impulse is also a good pant for hiking, biking or climbing in cool weather.
