The Basic Performance T is made of the same 5.9 weight Intera yarn as the standard Basic T. These shirts are excellent at keeping you cooler in warm weather and warmer on chilly days. The shirt feels much like cotton, yet packs up at half the size and weight of a cotton t-shirt, granting you more cargo space. Looking for something even smaller? Check out the Vapor Micro Performance T which packs at 25% of a regular cotton t-shirt.

Sound RIDER! Cleaning Tips:  When cleaning synthetics use a minimum of laundry products.  Their additives can clog fabric, inhibiting the wicking power of the fiber.  Never use scented detergents or bleach and never-never use dryer sheets or fabric softeners.  For the best results use a product designed specifically for cleaning synthetic base layers like Nikwax' BaseWash. Always wash your synthetics separate from cotton garments.  This will keep cotton fibers out of the fabric and drastically reduce drying time by 50% or more.
