I am loving this top. I am in the forces and bought this while I was on tour. I found it pretty much suitable for running in most environments and weather. The only annoyance I had were the toggles which hit your face while you run if you don't tie them or take them out. Colour has kept really bright despite lots of washes, and the thumb holes are great for those early morning frosty runs. Zipper goes quite low which is also great as you warm up you can let more air through. I also wore this quite a lot as a "chill out" top as it looks pretty cool just with a pair of joggers on its own. Really comfortable and would recommend.
