Making a running jacket that can protect you from wet weather while not causing you to overheat is tricky. It requires the right weight of cloth, intelligent design details, and consideration of features that actually benefit runners. We've looked at all types of jackets to find solutions to such specific problems, and our latest running shell borrows structural elements from cycling gear and rowing jackets.
Though it relies on water-resistant nylon to keep you dry, the jacket is fully mesh-lined to keep the fabric off your skin, and has strategically-placed zip vents for adjustable temperature control. Shoulder vents allow air to flow in, and pit vents (along with a lateral back vent) allow excess warmth to flow out. The stand collar can be engaged to help trap body heat when it's chilly.
Reflective hits make you visible both from the front and the back. The optional drop tail prevents the splash from your shoes from muddying your shorts. Zip front pockets keep gloves or valuables secure, and a zip back stash pocket allows for a bit of extra cargo without adding bulk. Finally, oversized zipper pulls (on both pockets and vents) make them easy to manipulate while running, even when you're wearing gloves.
