It's tighter thread count to keep the boys happy
The elastic is heat sensitive and conforms to your actual body size to keep best blood flow for circulation between the upper and lower half of your body. The tighter thread count is also heat sensitive for winter and summer wear. In hot summer months it expands almost like netting for air flow keeping body heat lower. In winter it contracts to a thinner thread count to keep body heat in. It is also self cleaning and repells skid marks in the aft section. It's also reversable and has a half life of 32 years. Biodegradable if left in direct sunlight for 72 minutes and 7 seconds.
