MERGE4 is excited to announce a new partnership with San Diego Zoo Global. The Santa Cruz-based sock brand is joining the fight to end extinction by donating a portion of proceeds from three animal-themed sock designs to the San Diego Zoo Global Wildlife Conservancy.

The MERGE4 X END EXTINCTION collection includes MERGE4’s Zebra Lite and Cheetah Lite socks with artwork from Taylor Reinhold, and their Lion Lite socks with artwork from Shaun Logan.
