Product Description: Spend the whole weekend in nature with everything you need right there. The Gregory Baltoro pack offers plenty of space in a feature-rich silhouette that&';s optimized for comfortable carrying. The Gregory Baltoro is one of the classic backpacks for backcountry adventuring. I used an older, slightly larger version (the Baltoro 75) while on a 7-month trek through the Andes of South America. Recently, I got a chance to test out the revamped design in advance of its spring 2022 release. I loaded up a good 35lbs in the 65-L pack and took to the red cliffs of Sedona, Arizona, to hike several miles over mixed terrain.
