Down Socks

These Down Socks are made from your choice of lightweight nylon fabrics and 850+ fill power premium goose down. They have elastic ankle cuffs and come with a stuff sack.


20d - This ripstop nylon is the most durable fabric that I offer. It has a DWR treatment applied to the outside surface, so it will resist a small amount of water before allowing it to get the down inside wet.

Pertex Quantum - This is a different 20d nylon that is softer and slightly lighter than my standard 20d fabrics. It also has a DWR treatment. A very good all-around fabric.

10d - There are two varieties of this fabric, both of which are very light and soft: the black has a good DWR treatment, and is thus better for the shell of a garment, and the gray and tan are more breathable, and thus better for the lining of a garment. There will be very light down leakage from the gray and tan 10d fabrics.

M50 - limited quantities - very light, very water-resistant, very wind-resistant, but has limited breathability.

Down Fill

Each pair of socks is stuffed with a varying amount of 850 fill power down. Check the chart below for the standard amount of fill for your size. You can add extra down for increased loft and warmth if you wish. Extra down fill is recommended but not required.

The following is an estimated temperature rating for the overfill levels:



The XS size is great for kids!

The weights below are for the 20d nylon, so the use of any other fabrics will result in lighter socks.
