DetailsBuilt with a double ripstop, the 2019 Clear Creek 20 WSD is as durable as it is versatile. Whether you’re battling cold winds above tree line or battling the traffic on your daily bike commute, the Clear Creek can endure it all. Its Anvil Airway ™, airmesh backpanel and dual density EVA/PU contoured shoulder straps make for an ultra-comfortable carry despite the weight of heavy gear or loaded layers. The Clear Creek 20 WSD is built with a 3L hydration sleeve, front panel expansion pocket, side panel mesh pockets, and dual tool/trekking pole carry. From your puffy jacket to your extra socks to excess amounts of trail mix (no raisins, please), the Clear Creek 20 has room for the essentials—and then some. What makes this pack women’s specific? On select Mountainsmith backpacks, they’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.
