Finally, sheer pantyhose and knee high socks that won't snag as soon as you get them! The Resistance collection of snag resistant pantyhose by Sanpellegrino has been specially developed using innovative, double-thread technology that uses two threads in place of the standard one. The result is snag-resistant, ladder-resistant hosiery, even in the low-denier styles. You can expect the sheer Resistance pantyhose and no-snag knee high socks to last around 16 wears without damage, and the opaque pieces for much longer! Plus, this long-lasting Sanpellegrino hosiery collection also holds it shape wash after wash. Never get a pantyhose ladder again - if you're looking for hosiery that will stand the test of time and the rigors of daily life, this is it.
