Snag Marl tights are 80 denier - so they're super snuggly when its cold but keep you cool when its hot thanks to their breathable, aerated yarn. With a lovely melange effect with a mix of different coloured yarns in one thread, these add an extra dimension to any outfit. Premium Ingredients – Most tights are made with Nylon 6 manufactured in China, they have super high emissions, and are designed to wear out. We use Nylon 66 and Nylon 11 in our Polyamide tights – New, never worn, I lost a lot of weight and need to get new sizes in everything. My dogs are not allowed in my closet, but I do have a pet friendly home so I can't rule out the stray dog fluff.
