High Quality Filter Socks

The feel and construction of these socks is top notch.
Thanks for offering them and at such a fair price.


7/5/2019: I received my 4" socks today fast free shipping product is as described. one suggestion I would make is to display the socks with a black background on your site so they can standout. other then that look & feel heavy duty and will do a great job trapping crud

Thank you.
