Calvin Klein has also come out with the Pro Stretch Reflex line, which varies from Pro Stretch in its fabric composition. While Pro Stretch is made of a cotton blend, Pro Stretch Reflex has more nylon giving it the softness and athletic stretch of a microfiber blend.
Calvin New Brief/Trunk:

Another new line from CK that we are excited about is the Pro Stretch Fun. If you have an appreciation for quality underwear but desire a bit more playfulness in your underwear, the Calvin Klein Pro Stretch Glow Hip Brief and Trunk are sure to please. The waistband will glow-in-the-dark and is sure to brighten up a dull night.
Calvin Klein’s Body Boost line has expanded to include a Rear Boosting Trunk. This innovative pair of underwear offers the same comfort, durability, and flexibility you’ve come to expect from CK but with a hidden support for a sexier rear silhouette.
The ever popular Calvin Klein Steel Cotton line is now available in three new, but limited edition colors: Amazon, Harbor, and Wheat.
