A few asked how do I cap my windsocks specially when I guide. I simply add a pushnut under the top rubber washer. Although alot like it uncapped because its easier to remove the sock to wash.

I like to cap it because they sometimes fall off if you pick up by pulling the bag.

Here is where I get my caps from. They are very cheap ($5 for 100) and fit perfectly.
