I would go with the Nano puff, it is synthetic so they run a little bit warmer. The Down sweater is described as being good for chilly environments, and suffers poor performance in wet environments, while the nano puff sweater is rated as good for "cold" environments and is good for all climates.
This sweater is warm down to 25- 30 degrees. It is not a Winter coat to be worn too much below freezing or in the freezing wind or snow. It has Goose Down Feathers. Sleeve length depends on the size. There is a sizing chart on our site that tells you sleeve length per size. You can return it without a hassle if the size does not fit.
