This is for the long, tough runs on the trails: the Patagonia Storm Racer Jacket will help all of you runners out there to defy the harshest of conditions. This ultra-light, slim-fitting, 3-layer synthetic running jacket is not only waterproof and windproof but is also very breathable and thus perfect for strenuous trail runs. The jacket has a zipped chest pocket, which not only serves as storage, but can also transform into a stuff sack for the jacket! Thus, the jacket will not only fit in any rucksack, but it will also be extremely easy for you to take it on and off and pack away whilst running! The high collar and the hood provide additional weather protection. The Patagonia Storm Racer Jacket is perfect for wearing over base layers and light mid layers.
