Features

45L women's pack with adjustable, lightweight features designed for all-day comfort and through extended overnight pursuits 

Comfort and support through contoured, anatomically curved back panel with body mapped foam for a precise fit with ventilation. Full-zip back panel provides duffel-style access to the pack interior 

Secure, comfort fit with articulated Open Range Hip Belt that threads behind the compression molded back panel for positive load transfer to the lumbar, providing stability with flexibility 

Cut-to-fit hip belt provides a tight wrap on hips and eliminates gaps between body and pack. Dual hip belt stabilizer straps allow the upper and lower section of the hip belt to be adjusted separately for a custom fit 

Women’s custom fit adjustments on contoured shoulder straps and hip belt keep pack flush against your torso. Load lifter straps allow fine tuning of weight distribution 

Balanced pack weight is achieved through our unique Hoist Compression system that pulls pack weight inward and upward for positive load transfer, while raising the bottom panel up to secure the load

What’s in a Name?

Rarer than a rainbow, a Sun Dog is a solar phenomenon that has been astounding humans since ancient times. Most commonly seen on clear, crisp winter mornings, the Lakota refer to the circular array of colors surrounding the sun as Wíačhéič'ithi, which can be loosely translated to “The Sun Makes A Campfire For Himself”.
