After two initial releases, a third addition has been made to the longstanding collaboration between Sorel and Boston boutique Concepts. Coming in the form of a ruggedly designed Sentry Boot, this collaboration will undoubtedly catch the attention of those with a passion for the outdoors. The boot features a waterproof outer and two removable wool liners in red and brown, protecting the wearer from the cold. Two lace variations complimenting the colors of the wool liners come standard also. Available starting November 11 both in-store and online, for more information check out Concepts’ online store.
