First of all, I had to wait about 6 months for this to be delivered after paying for it. So, was delivered in the summer, when I didn't need it. In the mean time - I bought a Dryrobe.
I can now write a review and compare the two. The Ekosy definitely keeps you warm, as does the Dryrobe.
The main difference is how they perform in the rain. Sadly, the Ekosy is not 100% waterproof, whilst the Dryrobe is. If you are out in the rain, even moderate rain, for any length of time, your shoulders get wet....
