The Incendo Jacket uses the same fabric as the Incendo Vest but has some obvious significant differences. It has no mesh rear panel but mesh panels under the arms to provide temperature control. Obviously designed for cooler temperatures and/ or early morning/ late evening runs. It has reflective strips to increase visibility and at 119g is super light. At the top of the summit in testing it provided perfect protection from the wind and importantly it will reflect light rain. It has a trim fit and therefore when running it did not flap or move around in the wind. It is a product that is designed to ‘fit’ the body and in doing so I suggest that you make sure that you get the correct fit. I personally found the jacket and the vest sized a little large, so, if you are around a 38″ to 40″ chest I would recommend a ‘small’. Like the Incendo Vest it has a small pocket and the jacket will stow into it. Inside the zippered pocket is a media pocket with MP3 cord passage. In use it is a pleasure to wear. Once on you don’t even know you are wearing it. Perfect. When running or racing this jacket offers the perfect combination of weight, size and practicality. Obviously should you anticipate ‘harsh’ conditions then this jacket may very well be too ‘light’ and I would recommend the Visio FL Jacket. For 2013 the Incendo will also have the option of a ‘hood’. This product will be called Incendo Hoody.
