Extraordinary! That's the word that best describes these new styles of loungewear, made in two different fabulous all-nylon fabrics: (1) silky slippery nylon tricot and (2) sexy sheer nylon. The tricot styles are semi-opaque, sensuous, and delightful to wear. The sheer styles are cool and comfortable for hot weather because the open knit breathes incredibly well. They're both more comfortable than all the silk in China, either by themselves (indoors) or under outer clothes! Both fabrics will give added glide under your pants. They're made exclusively for us by a US company who sews them from US-made knitted fabrics to our design specifications for men. The pants and kilt liner feature a very thin elastic waistband which is extremely stretchy. We omitted a fly so that when worn as lounge pants and pajamas, you can relax and hang out without anything else hanging out! And now our new kilt liners and shirts are a great addition to this growing line. If you want to wear the world's most comfortable loungewear, this is it! Try it today and prepare to be pleased!
