These bright blue HERA Climb4Life locking carabiners by Petzl play a key role in the gear fleet at Vail, Colorado’s Apex Mountain School. Great for use climbing both rock and ice, the simple, compact design makes it a useful tool, especially due to the keylock design, which creates a strong, snag-free design at the closure. Another nice feature is the red band indicator visible when the carabiner is not fully locked, making a quick visual safety check possible before heading on a rock climbing outing. The vibrant blue color is bold, an easily recognized tool among the palette of climbing gear on your rack, and it also symbolizes the Hera Climb4Life mission of eliminating ovarian cancer by promoting health, education, research, and awareness. Petzl donates $1 from the sale of each carabiner to HERA Women’s Cancer Foundation. HERA is dedicated to empowering women and expanding awareness of women’s cancers through its vision, as developed by founder Sean Patrick, an avid outdoorswoman and climber who died of ovarian cancer in 2009.
