Experience elite comfort with ZQ™ certified merino wool sourced from premium New Zealand farms. Representing only 0.3% of global wool production, these ultra-fine fibers provide unmatched softy, superior moisture management, and trace-from-farm-to-garment transparency under strict animal welfare standards.

How do you make delicate merino wool rugged enough for alpine trails? The answer lies in LincSpun® technology.

By meticulously wrapping and supporting the merino core with two strands of high-tenacity filaments, we give the soft wool an ultra-strong "inner skeleton."

The result is a machine-washable, shape-retaining technical garment that preserves all of wool's natural benefits while conquering its physical limits.

Engineered specifically to meet the strict mandatory gear requirements of UTMB CCC and above, the Wonderland is optimized for the unpredictable.

It thrives as a dynamic, thermoregulating base layer in volatile mountain weather, and excels as an antibacterial, odor-resistant training tee during high-intensity, multi-day pushes. Lightweight and uncompromisingly protective, it is the ultimate armor for your ultra-distance pursuit.
