Purchased two of these jackets, one for each of our whippets. Have been used in both light and heavy rain with good results, completely dry underneath. The jackets are adjustable around the chest which makes them a great choice for whippets or other sighthounds which are more difficult to fit properly. The materials and construction seem quite robust and the attention to detail is evident with the rear leg elastics and reflective strips. Would give them 5 stars if only they had better coverage further up the neck, where our dogs still get wet in these jackets. Will be good enough for the shoulder seasons though.
