Is there really that big of a difference between the parka and the jacket version? I'm asking because there are a lot more complaints in the reviews for the parka version concerning the material tearing, the hood and zippers. I was originally under the impression the only real difference between the two is the length before really reading the reviews.

There is a definite difference! The Sub Zero doesn't have the Conduit shell like the Parka SL!

Answer for joh3343548: Hi there! I own the Mt. Hardwear Subzero SL Parka, and have seen the Mt. Hardwear Subzero Jacket. Here are your answers: 1) The material(s) on both are the same! 2) The Parka is simply warmer - since it is longer and covers more or your body. (Obviously in very cold/frigid weather, if the areas below your waist is covered, as is the case with the parka, you will be warmer. Conclusion: The Mt. Hardwear Subzero SL Parka is a better choice if you want to be warm, and who doesn't!! So to joh3343548 and everyone else who is thinking of buying a Mountain Hardwear jacket or parka - the best choice is the Mountain Hardwear Subzero SL Parka!! You will all be happier if you make this your wiser choice!

The only difference between the Parka and the Jacket are a couple of pockets and the overall length itself. The material package is exactly the same between the Jacket and the Parka. Not sure why there are more issues with the Parka over the jacket. It must nothing more than a coincidence...
