Additionally, the Hyperbolic XL boasts Outlast temperature control technology and a Comfort Tech Gel tongue.
The Hyperbolic XL's Clarino DS-30 Microfiber upper is super lightweight and ensures a snug, comfortable fit and is made entirely of environmentally friendly materials. Its Chevron Comfort Spike outsole design provides the Hyperbolic XL with superior traction in most conditions while reducing clogging between spikes. Meanwhile, the Hyperbolic XL's Outlast temperature control technology utilizes a patented temperature-balancing material which absorbs and releases body heat in warm weather and traps it in during colder weather. The Callaway Hyperbolic XL is available in black, white/silver and white/black.
