I bought the original winter jacket, I originally bought the wrong size, Arrak was quick to send me the correct size within a timely manner. The winter jacket is warm, current temperature is 30 F during the day and and low as 12 F a night and the cold does not penetrate the jacket. The winter jacket runs a size small in my opinion, hence, the reason why I had to exchange it. Lots of pockets with zippers, and best of all the fabric does not make any crackling sound when you get your treats or ball out. Thanks Arrak.
