Mountainsmith Apex 55 WSD

Manufacturer's Description

Designed specifically for the female backpacker, the 2019 Apex 55 WSD is built for more efficient, more comfortable carry from thru-hikes to multi-night backpack excursions. 

Efficient pack carry starts with the hips. The Apex 60 is built with our Tuning Fork Waistbelt, designed to cup the iliac crest hip bone for a more dynamic fit and improved load transfer. Increased padding on the lumbar pad and our signature Delta Load Compression System stabilize and transfer weight for more efficient and comfortable carry. With a sock-style shoulder strap construction (no seams or hard edges means no digging into the body), increased padding on the waistbelt, adjustable torso range, and a hex-ridged backpanel, the 2019 Apex 55 WSD offers unmatched comfort on every adventure. On trail, the advanced, tubular aluminum frame keeps the weight lower without sacrificing performance. Whether you’re on the trail or at your campsite, reach for the U-shaped zipper for easy access into the main compartment. Store the essential in the zippered top lid (secondary map pocket inside) and stash your phone in the stretch mesh zippered waistbelt pockets.

What makes this pack women’s specific? On select Mountainsmith backpacks, we’ve designated specific regions of the pack fitment and sizing to better accommodate female torso structure. Precurved shoulder straps and waist belts as well as canted angles and contact points have been fine tuned for a better contour, a truer fit, and more efficient pack carry over unisex styles.
