We found this hardcore green alternative on Etsy from NaturallyNatalies. For under 7 dollars you could save money and materials with a 100% cotton fabric panty liner. Ok, this is somewhat on the fringe but valid none the less. Comprised of "a core of 2 layers hemp fleece and 2 layers cotton sherpa. Hemp is 3-4 times more absorbent than cotton, so it makes for a thinner pad." This liner is reusable, natural, and effective and clips securely into place with a polyresin snap fixture. This product is thin and is capable for heavy days, as backup for tampon or cup products, or for everyday security. Sorry for all the details but we liked the find and the idea!
