>>906013Gortex isn't water-proof. The last thing you want is to have your jacket saturated with down underneath.
>>906024It looks like most of their "ultra light" down jackets are $60+. I couldn't find the fill number on Uniqlo's website, but as said above, the weight and volume savings aren't significant enough to justify another $20 when you can get something like a Hawke & Co off Amazon.
>>906038Down jackets are hardly windproof, especially if they are packable. Nylon breathes... If it's raining, of course it may be cold enough to wear a puffy...
>>906042There might be examples of such a jacket, but fill power of a down jacket to me is irrelevant. The cubic cm and weight is negligible when backpacking. A quality sleeping bag is another story. Perhaps if it's constantly below freezing and you need more fill as opposed to fill power, I would look into a pricer jacket. For three seasons, save your money and get any $50 down jacket you find on Amazon.
