"Well, this has worked out nicely. I'm not really a silk guy but I decided to test these pajamas for the heck of it, and I'm glad I did. I'm 5'10", 180lbs and wear 36" pants, so I ordered the large as per the sizing chart, and the sizing is *perfect*. The pants fit like a dream, just tight enough to stay at my waist while loose enough to avoid any discomfort. It almost feels as if the waistband isn't there. I'll wear these pants until they fall apart." Indulge in ultimate luxury with our handcrafted Men's Silk Pajama Pants. Made of 100% natural mulberry silk, these pajama pants are silky-smooth, durable and hypoallergenic making them ideal for those with sensitive skin or allergies.
