Based in Poland, Pajak makes a nice looking down pant they call Ghost Pants. Ghost pants feature a flexible waist adjustment, full-length zippers, and a reinforced bottom.

It’s challenging finding any down garment at this price point worth buying, Tapasimme has engineered an excellent budget option with this one that’s more or less unrivaled when it comes to versatility in function! For outdoor winter wear, look for a pair of pants with at least a 600 or 700 fill-power and at least 3 ounces of down. That’s a good base range; more than that will be very warm, and less than that will be better for activities where you’re likely to generate your own heat (winter running, snowshoeing, etc.). The quality or effectiveness of down is rated according to its fill power. Fill power is determined by measuring how many cubic inches can be filled with one compressed ounce of down, and it’s expressed as cubic inches per ounce (in³/oz). For example, if one ounce of compressed down lofts to a volume of 800 cubic inches, it is said to have a lofting power of 800. The higher quality the down, the higher its fill power. Since high-quality down requires fewer ounces to maintain the same level of warmth, it has a better warmth-to-weight ratio than that of a lower-quality down and can be used to create garments that are substantially lighter in weight. All of that being said, fill weight still matters.
