The new Bahner Extra Firm Hold Ups are a 140 denier fabric, meaning the fabric is a robust one, but are knitted in such way that they are as sheer as a 40 denier. But the really impressive number is its compression factor. Most compression and support tights only reach a 12 on the compression scale. Bahner's new product stands at a colossal 18. Designed to provide the maximum support possible, they are robust, powerful and give your legs an impressive boost of vitality. Please check with your doctor before picking a higher compression than you're used to. Bahner 140 Denier Extra Firm Support Hold Ups ()
