We’re teaming up with Friends Of Berthoud Pass for an evening of backcountry education, good company + a few perks for getting mountain ready.
October 15 at the Halfdays Denver Flagship. Spots are limited. RSVP at the link in bio.
*This clinic is an introduction to avalanche awareness and backcountry preparedness, not a replacement for certified avalanche or backcountry training.
Fall, in our favorite shades.
Annice, our Design Director, and Ryan, our Director of Global Merchandise, take us inside the moodboards, mountain moments, and inspiration that brought Fall 2026 to life.
