For Earth Day this year (April 22), 1921 Jeans is partnering with American Forests’ Global ReLeaf program to plant a tree for every pair of 1921 jeans purchased between April 15th and May 15th. Global ReLeaf plants trees to restore ecosystems in both depleted urban and forested areas, and currently runs 500 projects spanning 21 countries.

Inspired by the program, 1921 is also launching Impressions by 1921 this fall, which will be a collection of shirts and denim made entirely with 100% organic cotton and natural dyes for both men and women. Pick up a pair of 1921s here, or donate $1 to plant a tree here.
