Special Limited Edition National Parks Collection in collaboration with artist Steve Wolf, featuring 6 Woolie Boolie 6" ribbed crew athletic cycling socks with different national park logos on the cuff, and the park's name on the foot. Featured parks include: Yellowstone, Big Bend, Hot Springs, Mesa Verde, Redwood, and Zion.

The DeFeet Woolie Boolie is a thick and padded Merino wool sock, suitable for winter cycling, hiking, or everyday wear, with a cult following for all the right reasons: woolie warmth, padded comfort, and durability.

Woolie Boolie socks with the RWS logo are 70% RWS-certified by CU 885920. The Responsible Wool Standard (RWS) is a set of audited protocols establishing high levels of sheep and land management practices, promoting healthy ecosystems, biodiversity, and animal and worker welfare.

100% of the wool in RWS-certified socks has complete traceability through each step of the supply chain from the ranches and sheep where it grows to the retailers where it is sold.

Our RWS-certified products use wool grown by the Shaniko Wool Company and RWS-certified family-owned ranches in the Western United States.
